    Thermos FUNtainer 10 oz vs 16 oz Food Jar: Which Size?

    As an Amazon Associate, TidyJapan earns from qualifying purchases. Links marked ‘Check price’ are affiliate links.

    Short answer: Get the 10 oz for younger kids and smaller lunches. It is shorter, cheaper ($20.99 at Thermos) and rated 5 hours hot. Get the 16 oz for bigger appetites or later lunch periods. It holds 6 oz more and is rated 7 hours hot and 9 cold. Both include a folding spoon.

    How we compare: every spec in this article comes from official manufacturer specifications and product pages (starting with Thermos’s official 10 oz product page and 16 oz product page), all listed under Sources below.

    I live in Japan, where soup jars are a normal part of packed lunches. In the US, the FUNtainer is the kids’ food jar most parents start with, and it comes in two sizes.

    I haven’t tested these side by side. Everything below comes from the manufacturers’ official product pages, linked at the end. If a spec isn’t published, I say so instead of guessing.

    All figures are from Thermos’s US product pages, checked October 2026. List prices are Thermos.com prices, not Amazon prices.

    Key differences at a glance

    • Capacity: The 16 oz holds 6 ounces more than the 10 oz, which is roughly a full extra serving of soup or pasta.
    • Rated time: Thermos rates the 16 oz for up to 7 hours hot and 9 hours cold, compared with 5 hours hot and 7 hours cold for the 10 oz.
    • Height: The 16 oz is about 1.35 inches taller at 6.65 inches, while the footprint is almost the same.
    • Price: Thermos lists the 10 oz at $20.99 and the 16 oz at $22.99.
    • What stays the same: Both have a wide-mouth twist lid, a folding spoon, a 0.6 lb listed weight and top-rack dishwasher cleaning.

    The 3 Differences That Matter

    1. How much food

    10 oz suits a side of soup or a small pasta portion for a younger child. 16 oz is closer to a full meal for an older kid.

    2. Rated hours

    The larger jar has the longer rating: 7 hours hot versus 5. If lunch is late, or you fill the jar early, the 16 oz rating gives more margin.

    3. Lunch-box fit

    The two jars have nearly the same footprint, but the 16 oz is 6.65 inches tall versus 5.3. Check the depth of your lunch bag.

    What’s the same

    Same wide-mouth twist lid, same folding spoon, same BPA-free double-wall stainless construction, and the same 0.6 lb listed weight.

    Who Should Buy Which?

    Choose the FUNtainer 10 oz if you:

    • Pack for a preschooler or early grade-schooler
    • Send soup as a side, not the whole meal
    • Have an early lunch period

    Choose the FUNtainer 16 oz if you:

    • Pack a full meal
    • Have a later lunch or a long day
    • Want the longer hot rating

    Soup Jars in Japan

    In Japan, Thermos sells soup jars rather than the FUNtainer line. Its JBR-401 holds 0.4 L, close to the 16 oz FUNtainer, and Thermos Japan rates it at 60 °C or above after 6 hours and 11 °C or below cold, at a suggested price of ¥6,050.

    A Kakaku.com reviewer who used the JBR-401 for about a year liked that the gasket comes apart and that the wide mouth is easy to clean. They called the heat retention average, and noted that a jar packed with chunky ingredients leaves little room for broth. (Third-party reviews, not our own testing.)

  • Thermos FUNtainer 12 oz vs 16 oz Water Bottle: Which Size?

    Thermos FUNtainer 12 oz vs 16 oz Water Bottle: Which Size?

    As an Amazon Associate, TidyJapan earns from qualifying purchases. Links marked ‘Check price’ are affiliate links.

    Short answer: For a preschooler or young grade-schooler, get the 12 oz. It has a push-button lid that covers a silicone straw. For tweens and teens, get the 16 oz. Thermos sizes it for older kids and gives it a push-button spout lid. Both are rated cold for 12 hours and are top-rack dishwasher safe.

    How we compare: every spec in this article comes from official manufacturer specifications and product pages (starting with Thermos’s official 12 oz product page and 16 oz product page), all listed under Sources below. We don’t run hands-on tests, and if a spec isn’t published, we say so. Last updated: October 2026.

    I live in Japan, where kids carry an insulated bottle to school almost every day. These two FUNtainer sizes are the ones US parents usually choose between.

    I haven’t tested these side by side. Everything below comes from the manufacturers’ official product pages, linked at the end. If a spec isn’t published, I say so instead of guessing.

    Origin China China

    All figures are from Thermos’s US product pages, checked October 2026. List prices are Thermos.com prices, not Amazon prices.

    Key differences at a glance

    • Drinking style: The 12 oz bottle drinks through a silicone straw, while the 16 oz bottle drinks from a spout.
    • Who it’s for: Thermos pitches the 16 oz for older kids, tweens and teens, and the 12 oz has the straw lid that suits younger children.
    • Size: The 16 oz is 1.5 inches taller at 8.4 inches but a little slimmer at 2.8 inches wide.
    • Price: Thermos lists the 12 oz at $16.99 and the 16 oz at $18.99.
    • What stays the same: Both are cold-only, vacuum-insulated stainless bottles rated for 12 hours, weigh 0.6 lb, and go on the top rack of the dishwasher.

    The 3 Differences That Matter

    1. Straw vs spout

    The 12 oz lid flips open to a silicone straw, and the cover protects it when closed. The 16 oz lid opens to a spout, and Thermos says the push button prevents accidental opening in backpacks.

    2. Capacity and age

    Four extra ounces matter more for a full school day plus practice. Thermos describes the 16 oz as sized for older kids who need more to drink through the day.

    3. Shape

    The 12 oz is short and slightly wider (6.9 in tall, 3.1 in wide). The 16 oz is taller and slimmer (8.4 in tall, 2.8 in wide), so check the side pocket of the backpack you already have.

    What’s the same

    Both are double-wall vacuum-insulated, BPA-free stainless bottles with a carry handle, rated to keep drinks cold for up to 12 hours. Neither is meant for hot liquids.

    Who Should Buy Which?

    Choose the Thermos FUNtainer 12 oz if you:

    • Have a preschooler or early grade-schooler
    • Want a straw your child already knows how to use
    • Want the lower price

    Choose the Thermos FUNtainer 16 oz if you:

    • Have a tween or teen
    • Need more water for sports or long days
    • Prefer a spout over a straw

    Kids’ Water Bottles in Japan

    Japanese kids usually bring a water bottle (suitō) to school, and Thermos Japan sells its own kids’ lineup rather than the FUNtainer. Its cold-only straw bottle FKA-350 holds 0.36 L and is rated at 11 °C or below after 6 hours. Thermos Japan also sells a 0.4 L straw bottle, the FHL-403F.

    A Kakaku.com reviewer who bought the FHL-403F for a two-year-old starting preschool praised the capacity, the wide mouth and the easy push button, and noted that replacement parts are easy to buy. They added that it costs more than cheap bottles but is worth it for durability. (Third-party reviews, not our own testing.)

    Thermos FUNtainer 12 oz vs 16 oz Water Bottle: Frequently Asked Questions

    Can I put hot drinks in a FUNtainer bottle?

    No. Thermos says both bottles are not for hot liquids.

    Are FUNtainer bottles dishwasher safe?

    Yes, top rack only, according to Thermos.

    How long do they keep drinks cold?

    Thermos rates both sizes for up to 12 hours cold.

    Which size is better for a kindergartner?

    The 12 oz, with its covered straw lid. Thermos aims the 16 oz at older kids, tweens and teens.

    Zojirushi SW-KA30 vs Thermos FUNtainer 10 oz: Kids’ Jars

    As an Amazon Associate, TidyJapan earns from qualifying purchases. Links marked ‘Check price’ are affiliate links.

    Short answer: Both hold 10 oz. The Thermos FUNtainer has a push-button lid that kids can open easily, a folding spoon stored in the lid, and top-rack dishwasher cleaning, and it’s rated “up to 5 hours hot.” The Zojirushi SW-KA30 has a leak-proof one-piece stopper and a pressure-relieving lid, and Zojirushi lists it at 136°F after 6 hours.

    How we compare: every spec in this article comes from official manufacturer specifications and manuals (starting with Zojirushi’s official product page and Thermos’s official product page), all listed under Sources below.

    I live in Japan. School lunch in Japan is usually served at school, but home-packed lunches for outings are a ritual. These are the two 10 oz jars US parents usually look at.

    I haven’t tested these side by side. Everything below comes from the manufacturers’ official product pages, linked at the end. If a spec isn’t published, I say so instead of guessing.

    Quick Comparison Table

    Spec Zojirushi SW-KA30 Thermos FUNtainer 10 oz
    Capacity 10 oz / 0.30 L 10 oz (290 mL)

    *Zojirushi rates heat retention with 203°F (95°C) water in a 68°F (20°C) room, and cold retention with 40°F (4°C) water in the same room.

    Key differences at a glance

    • Lid: The FUNtainer has a push-button pop-up lid for young kids, while the SW-KA30 has a screw-style one-piece stopper.
    • Heat rating: Zojirushi lists 136°F after 6 hours, while Thermos lists “up to 5 hours hot” without a temperature.
    • Shape: The SW-KA30 is short and wide at 4-3/8 inches tall, while the FUNtainer is taller and narrower at 5.3 inches.
    • Weight: The FUNtainer weighs 0.6 lb (about 9.6 oz), while the SW-KA30 weighs 11 oz.
    • What stays the same: Both are double-wall vacuum-insulated stainless jars with a 10 oz capacity.

    The 4 Differences That Matter

    1. Kid usability

    A push-button lid that pops open is the FUNtainer’s main selling point for young kids. The SW-KA30 has a screw-style lid with a one-piece stopper, which suits older kids and adults.

    2. Heat rating

    Zojirushi: 136°F after 6 hours. Thermos: up to 5 hours hot, with no temperature given. They aren’t the same kind of rating.

    3. Shape

    The SW-KA30 is short and wide (4-3/8 in tall). The FUNtainer is taller and narrower (5.3 in).

    4. Weight

    0.6 lb (about 9.6 oz) for the Thermos vs 11 oz for the Zojirushi.

    What’s the same

    Both are double-wall vacuum-insulated stainless jars with a 10 oz capacity.

    Who Should Buy Which?

    Choose the Zojirushi SW-KA30 if you:

    • Want the leak-proof claim
    • Want a published 6-hour temperature
    • Have an older kid or are packing for yourself

    Choose the Thermos FUNtainer 10 oz if you:

    • Have a young child who opens it alone
    • Want the spoon included
    • Want dishwasher cleaning

    Kids’ Food Jars in Japan

    Japanese school lunches are usually provided, but soup jars are common for packed lunches and outings. Zojirushi Japan sells the SW-KA30 under that same number: 300 mL, suggested for miso soup, with a 7 cm mouth, rated at 58 °C or higher after 6 hours and 10 °C or lower cold, in ice gray, matte green and beige. Thermos Japan has sold its own soup jars, such as the 500 mL JEB-500, now discontinued. The FUNtainer line is a US-market Thermos product.

    Japanese reviewers on Rakuten and Kakaku.com often say the SW-KA keeps soup warm until lunch, especially if the jar is preheated with hot water, and like its wide mouth and few parts; one recurring gripe is that the large lid is hard to open one-handed. (Third-party reviews, not our own testing.)

    For older kids or adults, the next sizes up are compared in SW-KA40 vs SW-KA52.

    SW-KA30 vs Thermos FUNtainer 10 oz: Frequently Asked Questions

    Is the FUNtainer dishwasher safe?

    Thermos says top rack only.

    Is the SW-KA30 leak-proof?

    Zojirushi says yes, when used according to the instruction manual.

    Which keeps soup hotter until lunch?

    The ratings can’t be compared directly. Zojirushi lists 136°F after 6 hours; Thermos lists up to 5 hours hot.

    Do both hold 10 oz?

    Yes.

  • Zojirushi Ms. Bento SL-NCE09 Capacity: How Much It Holds

    Zojirushi Ms. Bento SL-NCE09 Capacity: How Much It Holds

    As an Amazon Associate, TidyJapan earns from qualifying purchases. Links marked ‘Check price’ are affiliate links.

    Short answer: Zojirushi lists three bowls for the Ms. Bento SL-NCE09: a 10 oz main bowl, an 11 oz side bowl, and a 7 oz soup bowl, 28 oz in total. The jar is 5 x 4-3/8 x 8-1/8 inches, weighs 2 lb, and is rated to keep water at 149°F after 6 hours.

    How we compare: every spec in this article comes from official manufacturer specifications and manuals (starting with Zojirushi’s official product page), all listed under Sources below. We don’t run hands-on tests, and if a spec isn’t published, we say so. Last updated: October 2026.

    Check price: Zojirushi SL-NCE09

    I live in Japan. A stacked thermal lunch jar is a Japanese office classic. The question I hear most about the Ms. Bento is simple: is it enough food?

    I haven’t tested this jar. Everything below comes from Zojirushi’s official product page, linked at the end.

    Quick Spec Table

    Spec Zojirushi SL-NCE09
    Main bowl 10 oz
    Side bowl 11 oz
    Soup bowl 7 oz
    Total (sum of bowls) 28 oz
    Dimensions (W x D x H, excludes bag) 5 x 4-3/8 x 8-1/8 in
    Weight 2 lb 0 oz (listed as 2.00 lbs.oz.)
    Heat after 6 hours* 149°F
    Cold after 6 hours* 50°F
    Inner bowls 3, microwaveable
    Included Forked spoon with cover, tote bag
    Made in Thailand

    *Zojirushi rates heat retention with 203°F (95°C) water in a 68°F (20°C) room, and cold retention with 40°F (4°C) water in the same room.

    What the Numbers Mean

    1. What 28 oz looks like

    28 fl oz is about 3.5 US cups of volume. The 10 oz main bowl is about 296 mL, about 1.6 Japanese rice cups (180 mL each) of volume. That’s volume, not raw rice. Cooked rice takes up space differently; see my rice-cup explainer (how much rice a 5.5-cup cooker makes).

    2. Which bowl for what

    Zojirushi names a soup bowl (7 oz), so plan soup or miso there. The main and side bowls suit rice and a main dish.

    3. Weight and size

    At 2 lb and just over 8 inches tall it’s a real lunch box, not a pocket jar. The included tote bag also has room for a drink and snacks, according to Zojirushi.

    Who It’s For

    The Ms. Bento SL-NCE09 makes sense if you:

    • Want a hot multi-dish lunch without an office microwave
    • Can carry a 2 lb jar
    • Want microwaveable inner bowls

    Lunch Jars in Japan

    Insulated lunch jars like Ms. Bento come from a Japanese tradition of keeping rice warm until lunch. Zojirushi Japan sells a closely numbered model, the SL-NC09, with a 0.31 L rice bowl, a 0.33 L side bowl and a 0.2 L soup bowl. Zojirushi Japan puts the rice bowl at about 0.6 go of uncooked rice, about 1.5 rice bowls, and rates heat retention at 65 °C or higher after 6 hours. The SL-NC09 comes in stainless silver, and Zojirushi says it was released in 2007. Specs can differ from the US SL-NCE09, so check the US listing.

    Japanese reviewers on Rakuten often say the SL-NC09 keeps soup and rice warm until lunch when preheated, though some find the rice only lukewarm; many call it right for light eaters or kids but small for big appetites. (Third-party reviews, not our own testing.)

    Zojirushi Ms. Bento SL-NCE09 Capacity: Frequently Asked Questions

    How many ounces does the Ms. Bento hold?

    10 + 11 + 7 = 28 oz across its three bowls.

    Are the bowls microwaveable?

    Yes, Zojirushi lists three microwaveable inner bowls.

    Is the outer container washable?

    Yes, it’s a washable nonstick coated outer container.

    Is it enough for an adult?

    28 oz is more than either a 17 oz SW-EAE50 or an 18 oz SW-KA52 food jar.

  • Zojirushi SM-KHE48 vs SM-VA60: Which Travel Mug to Buy?

    Zojirushi SM-KHE48 vs SM-VA60: Which Travel Mug to Buy?

    As an Amazon Associate, TidyJapan earns from qualifying purchases. Links marked ‘Check price’ are affiliate links.

    Short answer: They’re almost the same height (9-1/8 vs 9-1/4 inches), but the SM-VA60 holds 4 oz more, is rated hotter after 6 hours (163°F vs 154°F), has a nonstick interior that’s OK for sports drinks, and an official leak-proof claim. The SM-KHE48 is slimmer and lighter (9 vs 10 oz) and has an uncoated SlickSteel interior.

    How we compare: every spec in this article comes from official manufacturer specifications and manuals (starting with Zojirushi’s official product page), all listed under Sources below. We don’t run hands-on tests, and if a spec isn’t published, we say so. Last updated: October 2026.

    *Zojirushi rates heat retention with 203°F (95°C) water in a 68°F (20°C) room, and cold retention with 40°F (4°C) water in the same room.

    Key differences at a glance

    • Interior finish: The SM-KHE48 has a polished SlickSteel interior, while the SM-VA60 has a nonstick coating that Zojirushi says is OK for sports drinks.
    • Capacity: The SM-VA60 holds 20 oz, 4 oz more than the SM-KHE48, for only 1/8 inch more height.
    • Heat retention: The SM-VA60 is rated at 163°F after 6 hours, while the SM-KHE48 is rated at 154°F.
    • Leak claim: Zojirushi calls the SM-VA60’s lid leak-proof, while the SM-KHE48 page does not use that word.
    • What stays the same: Both have a flip lid with a safety lock, are made in Thailand, and carry a 5-year US/Canada thermal warranty.

    The 4 Differences That Matter

    1. Interior finish

    SlickSteel is polished stainless, which Zojirushi says resists corrosion and repels stains. The SM-VA’s nonstick coating resists odors and stains, and Zojirushi explicitly says it’s OK for sports drinks.

    2. Capacity per inch

    For only 1/8 inch more height, the SM-VA60 holds 4 oz more. It’s 1/4 inch wider.

    3. Heat

    163°F vs 154°F after 6 hours.

    4. Leak claim

    Only the SM-VA page uses the word leak-proof.

    What’s the same

    Both have a flip lid with a safety lock, are made in Thailand, and carry Zojirushi’s 5-year US/Canada thermal insulation warranty.

    Who Should Buy Which?

    Choose the SM-KHE48 if you:

    • Want the slimmest, lightest mug
    • Prefer a bare stainless interior

    Choose the SM-VA60 if you:

    • Want more volume at nearly the same height
    • Carry sports drinks
    • Want the leak-proof claim

    Seamless Lids: The Japan Trend

    Zojirushi Japan has pushed hard on its “seamless” stopper, where the lid and gasket are one piece. Zojirushi says it launched the design in 2020 and expanded it to bigger sizes after customer requests, which led to the SM-VA60 and SM-VA72 in 2023. The SM-KHE48 uses a different flip-open lid with a disassembling stopper. Japan-market SM-VA colors are navy, mint blue and pale taupe, and the SM-VA60 is rated at 73 °C after 6 hours on Zojirushi Japan’s spec sheet.

    The handful of Japanese reviews on Kakaku.com mention easy washing thanks to the one-piece lid, that sports drinks are OK, and that ice fits the mouth; one reviewer wished a carrying case were offered. (Third-party reviews, not our own testing.)

    Sizes compared: SM-KHE36 vs SM-KHE48 and SM-VA60 vs SM-VA72.

    SM-KHE48 vs SM-VA60: Frequently Asked Questions

    Which holds more?

    The SM-VA60, 20 oz vs 16 oz.

    Which has a coated interior?

    The SM-VA60 is nonstick coated; the SM-KHE48 is SlickSteel stainless.

    Which keeps drinks hotter?

    The SM-VA60: 163°F vs 154°F after 6 hours.

    Can both hold ice?

    Zojirushi says the SM-KHE’s wide mouth fits full-size ice cubes, and the SM-VA’s 1-7/8-inch opening is easy to fill with ice cubes.

    Zojirushi SM-VA60 vs SM-VA72: 20 oz or 24 oz Bottle?

    As an Amazon Associate, TidyJapan earns from qualifying purchases. Links marked ‘Check price’ are affiliate links.

    Short answer: The SM-VA72 holds 24 oz versus 20 oz, is 1-3/8 inches taller, weighs 1 oz more, and is rated 167°F versus 163°F after 6 hours. Both have the same 46°F cold rating, the same five colors, and a leak-proof flip lid. Zojirushi says both are designed to fit most car cup holders.

    I live in Japan. The SM-VA is Zojirushi’s all-purpose flip-lid bottle, for iced water as much as coffee. The two sizes differ mainly in height.

    I haven’t tested these side by side. Everything below comes from the manufacturers’ official product pages, linked at the end. If a spec isn’t published, I say so instead of guessing.

    *Zojirushi rates heat retention with 203°F (95°C) water in a 68°F (20°C) room, and cold retention with 40°F (4°C) water in the same room.

    Key differences at a glance

    • Capacity: The SM-VA72 holds 24 oz, 4 oz more than the SM-VA60’s 20 oz.
    • Height: The SM-VA72 is 10-5/8 inches tall, while the SM-VA60 is 9-1/4 inches, on the same base.
    • Heat retention: The SM-VA72 is rated at 167°F after 6 hours, while the SM-VA60 is rated at 163°F.
    • What stays the same: Both share the leak-proof lid with safety lock, two-part lid, sports-drink-safe nonstick interior, and colors.

    The 3 Differences That Matter

    1. Capacity

    4 oz more in the 72. For all-day water, 24 oz is 3 US cups versus 2.5.

    2. Height

    10-5/8 vs 9-1/4 inches. Both share the same base, so cup-holder fit is the same, but the taller one sticks up higher.

    3. Heat

    167°F vs 163°F after 6 hours, a small gap.

    What’s the same

    Same leak-proof lid with safety lock, two-part lid that’s easy to clean, nonstick interior that Zojirushi says is OK for sports drinks, and the same colors.

    Who Should Buy Which?

    Choose the SM-VA60 if you:

    • Want a shorter bottle for bags
    • Drink coffee more than water

    Choose the SM-VA72 if you:

    • Want the most water per refill
    • Have room for 10-5/8 inches

    The SM-VA in Japan

    The SM-VA is a Japan-market model too, launched there in February 2023 under the name “TUFF” as part of Zojirushi’s seamless lid range. Zojirushi Japan rates the 600 mL SM-VA60 at 73 °C and the 720 mL SM-VA72 at 75 °C after 6 hours, with 8 °C cold retention for both. Japan colors are navy, mint blue and pale taupe. Japan also gets a bigger 950 mL sibling, the SM-VS95. Zojirushi Japan’s product page now marks the SM-VA60 and SM-VA72 as limited stock (在庫限定品), so availability may change.

    The handful of Japanese reviews on Kakaku.com mention easy washing thanks to the one-piece lid, that sports drinks are OK, and that ice fits the mouth; one reviewer wished a carrying case were offered. (Third-party reviews, not our own testing.)

    If 20 oz is more than you need, compare the 16 oz flip-lid mug in SM-KHE48 vs SM-VA60.

    Zojirushi SM-KHE48 vs Tiger MMJ-A048: Which 16 oz Travel Mug?

    As an Amazon Associate, TidyJapan earns from qualifying purchases. Links marked ‘Check price’ are affiliate links.

    Short answer: These are close twins: both are 16 oz one-hand flip-lid mugs rated at 154°F after 6 hours. Choose the Tiger MMJ-A048 for the lightest carry (about 6.7 oz vs 9 oz). Choose the Zojirushi SM-KHE48 for more colors and Zojirushi’s published 5-year US/Canada insulation warranty.

    How we compare: every spec in this article comes from official manufacturer specifications (starting with Zojirushi’s official product page and Tiger USA’s official MMJ-A page), all listed under Sources below.

    I live in Japan. Zojirushi and Tiger are the two big Osaka names in vacuum bottles, and these are their 16 oz one-hand mugs.

    I haven’t tested these side by side. Everything below comes from the manufacturers’ official pages, linked at the end. If a spec isn’t published, I say so instead of guessing.

    Dimensions (W x D x H) 2-5/8 x 2-7/8 x 9-1/8 in 2.60 x 2.83 x 8.58 in (6.6 x 7.2 x 21.8 cm)

    Colors (US) 7 colors 4 colors (Blue Black, Passion Pink, Snow White, Clear Stainless)

    US warranty listed 5-year thermal insulation warranty (US/Canada) Not listed on the product page

    Zojirushi rates heat retention with 203°F (95°C) water in a 68°F (20°C) room. Tiger’s MMJ-A048 page doesn’t state test conditions; Tiger’s manual for its export MMJ-A1 series uses the same 95°C water and 20°C room.

    Key differences at a glance

    • Weight: The Tiger MMJ-A048 weighs about 0.19 kg (6.7 oz), roughly 2 oz less than the SM-KHE48’s 9 oz.
    • Height: The Tiger is about 8.6 inches tall, while the Zojirushi is 9-1/8 inches.
    • Heat retention: Both are rated at 154°F after 6 hours; the Zojirushi lists 187°F after 1 hour and the Tiger 186°F or more.
    • Colors and origin: The Zojirushi comes in 7 colors and is made in Thailand, while the Tiger comes in 4 colors and is made in China.
    • Warranty: Zojirushi lists a 5-year US/Canada thermal insulation warranty, while Tiger’s product page lists no warranty term.
    • What stays the same: Both hold 16 oz, have a one-hand flip lid with a lock, and use 18/8 stainless steel with a polished, stain-resistant interior.

    The Differences That Matter

    1. Weight

    Tiger lists the MMJ-A048 at about 0.19 kg, roughly 6.7 oz. Zojirushi lists the SM-KHE48 at 9 oz. Tiger credits its spinning process, which thins the stainless inner shell, for the low weight.

    2. Size

    The footprints are almost identical (2.60 x 2.83 in for the Tiger, 2-5/8 x 2-7/8 in for the Zojirushi). The Tiger is about half an inch shorter, at 8.58 inches versus 9-1/8 inches.

    3. Heat and cold ratings

    This is a draw on paper. Both list 154°F after 6 hours. After 1 hour, Zojirushi lists 187°F and Tiger 186°F or more, and cold ratings are 48°F (Zojirushi) and 47°F or less (Tiger).

    4. Colors, origin, and warranty

    Zojirushi offers the SM-KHE48 in 7 colors, makes it in Thailand, and lists a 5-year thermal insulation warranty for products used in the US and Canada. Tiger USA lists 4 colors and China as the producing country, and its product page doesn’t state a warranty term.

    What’s the same

    Both hold 16 oz, open with one hand, lock shut for carrying, and use 18/8 stainless with a polished interior that each maker describes as stain-resistant.

    Who Should Buy Which?

    Choose the Zojirushi SM-KHE48 if you:

    • Want a wider choice of colors
    • Value a published 5-year US/Canada insulation warranty
    • Want a mug Zojirushi says fits full-size ice cubes

    Choose the Tiger MMJ-A048 if you:

    • Want the lightest 16 oz mug of the two
    • Want a slightly shorter bottle for a small bag
    • Plan to carry sports drinks (Tiger Japan says that’s OK)

    Tiger USA lists the MMJ-A048 on its product site, but it isn’t sold in Tiger’s own US online store, so check that a listing is new stock from a reputable seller.

    The View from Japan

    In Japan, Tiger sells this mug under the same model number, MMJ-A048, as part of its SAHARA MUG line of lightweight “Yume Jūryoku” (dream gravity) bottles. Tiger Japan lists the same 0.48 L capacity, 68°C or higher after 6 hours, 0.19 kg weight, and 4.3 cm mouth, plus a removable drinking spout and a fully washable body thanks to a laser-welded base. Tiger Japan’s manual site also lists a newer MMJ-A2 series (MMJ-A362/A482/A602).

    Japanese reviewers on Kakaku.com rate the MMJ-A048 highly, often praising its light weight, heat and cold retention, one-hand operation, and easy cleaning. Complaints include paint that chipped sooner than expected and a lid hinge that broke after a drop (one reviewer was able to order a replacement part). (Third-party reviews, not our own testing.)

    SM-KHE48 vs Tiger MMJ-A048: Frequently Asked Questions

    Which keeps coffee hotter, the SM-KHE48 or the MMJ-A048?

    On paper they tie. Both are rated at 154°F after 6 hours. After 1 hour, Zojirushi lists 187°F and Tiger lists 186°F or more.

    Which is lighter?

    The Tiger MMJ-A048, at about 0.19 kg (6.7 oz) versus 9 oz for the Zojirushi SM-KHE48.

    Do both have a one-handed lid?

    Yes. The SM-KHE48 has a flip-open lid with a safety lock, and the MMJ-A048 has a one-push lid with a one-hand lock.

    Can I put sports drinks in them?

    Tiger Japan says sports drinks are OK in the MMJ-A if you clean it right after use. Zojirushi’s SM-KHE page doesn’t mention sports drinks.

    What happened to the Tiger MMZ-A501?

    An earlier version of this page compared the MMZ-A501, which Tiger Hong Kong lists as discontinued. The MMJ-A048 is the 16 oz Tiger mug on Tiger USA’s site.

    Key differences at a glance

    • Capacity: The SM-KHE48 holds 16 oz, 4 oz more than the SM-KHE36’s 12 oz.
    • Height: The SM-KHE36 is 7-3/8 inches tall, while the SM-KHE48 is 9-1/8 inches.
    • Heat retention: The SM-KHE48 is rated at 154°F after 6 hours, while the SM-KHE36 is rated at 147°F.
    • What stays the same: Both share the same footprint, flip-open lid with safety lock, removable stopper, and wide mouth.

    The 3 Differences That Matter

    1. Capacity

    4 oz more in the 48. A US “tall” coffee is 12 oz and a “grande” is 16 oz, so match the mug to your usual order.

    2. Height

    7-3/8 vs 9-1/8 inches. The shorter 36 fits more easily in small bags and under some coffee-machine spouts.

    3. Heat

    154°F vs 147°F after 6 hours, and about the same after 1 hour (187°F vs 185°F).

    What’s the same

    Same footprint, same flip-open lid with safety lock, stopper that comes apart for cleaning, and a wide mouth that Zojirushi says fits full-size ice cubes.

    Who Should Buy Which?

    Choose the SM-KHE36 if you:

    • Drink a 12 oz cup
    • Want the most compact mug

    Choose the SM-KHE48 if you:

    • Drink 16 oz or refill once
    • Want Deep Cherry or Emerald

    What Japan Buys Instead

    The SM-KHE36 and SM-KHE48 appear on Zojirushi’s US site, while Zojirushi Japan’s current lineup features “seamless” models whose stopper and gasket are one piece to cut down on parts to wash. One example is the SM-VA series, sold in Japan in 600 and 720 mL with navy, mint blue and pale taupe colors. Japanese buyers call these “mugs” (マグ), meaning bottles you drink from directly. If easy cleaning matters most, it’s worth checking whether a seamless model is available in the US.

    The handful of Japanese reviews on Kakaku.com mention easy washing thanks to the one-piece lid, that sports drinks are OK, and that ice fits the mouth; one reviewer wished a carrying case were offered. (Third-party reviews, not our own testing.)

    If you want a bottle with a leak-proof lid instead, compare SM-KHE48 vs SM-VA60.

    SM-KHE36 vs SM-KHE48: Frequently Asked Questions

    How heavy is the SM-KHE48?

    Zojirushi lists 0.09 lbs.oz., which means 9 ounces.

    Does it fit ice cubes?

    Zojirushi says the wide mouth fits full-size ice cubes.

    Is the SM-KHE leak-proof?

    Zojirushi’s page mentions a safety lock and tight-fitted lid but doesn’t use the word leak-proof.

    • What stays the same: Both share the 3-7/8-inch footprint, 2-7/8-inch opening, Therma Chamber lid, and leak-proof one-piece stopper.

    The 3 Differences That Matter

    1. Capacity and portion

    18 oz is a generous adult serving of soup or stew. 14 oz suits a normal lunch portion, and 10 oz is a snack or a child’s meal.

    2. Heat retention climbs with size

    136°F, 147°F, then 153°F after 6 hours. If you pack early and eat late, size up.

    3. Color

    Ice Gray isn’t offered on the SW-KA52.

    What’s the same

    Every size shares the 3-7/8-inch footprint, 2-7/8-inch opening, Therma Chamber lid, and leak-proof one-piece stopper.

    Who Should Buy Which?

    Choose the SW-KA40 if you:

    • Want a standard lunch portion
    • Want Ice Gray

    Choose the SW-KA52 if you:

    • Want the most food and the best 6-hour rating
    • Have room for a 5-3/4-inch jar

    400 or 520 mL: How Zojirushi Japan Frames It

    Zojirushi Japan sells both sizes, and frames the choice by what goes inside: the 400 mL SW-KA40 for soups with large chunks, and the 520 mL SW-KA52 for filling curry or stew. Japan specs rate the SW-KA40 at 64 °C and the SW-KA52 at 67 °C or higher after 6 hours, both with a 7 cm mouth. In Japan the SW-KA52 comes in matte green and beige, while the SW-KA40 also comes in ice gray. Japanese suggested prices are 6,600 yen and 7,150 yen. US colors may differ.

    Japanese reviewers on Rakuten and Kakaku.com often say the SW-KA keeps soup warm until lunch, especially if the jar is preheated with hot water, and like its wide mouth and few parts; one recurring gripe is that the large lid is hard to open one-handed. (Third-party reviews, not our own testing.)

    SW-KA40 vs SW-KA52: Frequently Asked Questions

    Which SW-KA keeps food hottest?

    The SW-KA52: 153°F after 6 hours.

    Are they all the same width?

    Yes, 3-7/8 inches.

    Is the SW-KA52 available in gray?

    Zojirushi SW-KA40 vs SW-EAE50: Which Food Jar to Buy?

    As an Amazon Associate, TidyJapan earns from qualifying purchases. Links marked ‘Check price’ are affiliate links.

    Short answer: Zojirushi lists both at 147°F after 6 hours, even though the SW-KA40 holds 3 oz less (14 vs 17 oz). The KA40 gets there with its newer Therma Chamber lid, and it also adds a leak-proof one-piece stopper, a pressure-relieving lid, and a wider 2-7/8-inch opening. The SW-EAE50 is the pick if you just want the bigger portion.

    How we compare: every spec in this article comes from official manufacturer specifications and manuals (starting with Zojirushi’s official product page), all listed under Sources below. We don’t run hands-on tests, and if a spec isn’t published, we say so. Last updated: October 2026.

    I live in Japan. Zojirushi calls the SW-KA series the food jar line “with the highest heat retention in Zojirushi history.” Comparing it with the older SW-EAE50 shows what that means in practice.

    I haven’t tested these side by side. Everything below comes from the manufacturers’ official product pages, linked at the end. If a spec isn’t published, I say so instead of guessing.

    *Zojirushi rates heat retention with 203°F (95°C) water in a 68°F (20°C) room, and cold retention with 40°F (4°C) water in the same room.

    Key differences at a glance

    • Heat retention: The SW-KA40 matches the larger SW-EAE50 at 147°F after 6 hours despite holding less (14 oz vs 17 oz).
    • Lid: The SW-KA40 has a leak-proof one-piece stopper with pressure relief, while the SW-EAE50’s gasket lid is described as minimizing leaks.
    • Shape: The SW-KA40 is shorter and wider (3-7/8 x 5 in), while the SW-EAE50 is narrower and 1 inch taller.
    • What stays the same: Both use 18/8 stainless with a SlickSteel finish, are made in Thailand, and carry a five-year thermal warranty in the US and Canada.

    The 3 Differences That Matter

    1. Same heat rating, less volume

    Smaller jars normally lose heat faster, yet the KA40 matches the larger EAE50 at 147°F. That’s the Therma Chamber lid, which Zojirushi says uses small internal chambers to cut heat loss.

    2. Leak-proof and pressure relief

    Zojirushi calls the KA40’s one-piece stopper leak-proof when used per the manual, and says the lid relieves pressure from hot food as it opens. The EAE50’s lid is described as minimizing leaks.

    3. Shape

    The KA40 is shorter and wider (3-7/8 in wide, 5 in tall). The EAE50 is narrower and 1 inch taller. The KA40’s 2-7/8-inch mouth makes it easier to eat from and clean.

    What’s the same

    Both use 18/8 stainless with a SlickSteel finish, are made in Thailand, and have Zojirushi’s five-year thermal insulation warranty in the US and Canada.

    Who Should Buy Which?

    Choose the SW-KA40 if you:

    • Want the leak-proof stopper for a bag
    • Want the widest opening
    • Are fine with 14 oz

    Choose the SW-EAE50 if you:

    • Need the extra 3 oz
    • Want a slimmer jar
    • Want more color choices

    The SW-KA at Home in Japan

    The SW-KA is also sold in Japan, where Zojirushi launched the series in 2022 as a soup jar (スープジャー). On Zojirushi Japan’s site, the 400 mL SW-KA40 comes in ice gray, matte green and beige, has a roughly 7 cm mouth, and is rated at 64 °C or higher after 6 hours. Japanese marketing focuses on the “seamless” lid, where the stopper and gasket are one piece, and on a mouth wide enough to fill with a ladle. Colors and packaging can differ from US listings, so check the US listing.

    Japanese reviewers on Rakuten and Kakaku.com often say the SW-KA keeps soup warm until lunch, especially if the jar is preheated with hot water, and like its wide mouth and few parts; one recurring gripe is that the large lid is hard to open one-handed. (Third-party reviews, not our own testing.)
