Short answer: Get the Hario Clear Tea Pot FNC-45-T (450 ml, $27.50 at Hario USA) if you brew for one or two people, about two 8 oz cups per pot. Get the FNC-70-T (700 ml, $33.50) if you brew for two or three, about three 8 oz cups. Both are the same lidless design: loose leaves go straight into the glass pot, and a PCT resin cap with a built-in filter and spout sits on top. Because the leaves stay in the water, choose the size you will pour out in one go.

How we compare: every spec in this article comes from Hario’s official pages and manual (starting with Hario USA’s Clear Tea Pot page and Hario Japan’s 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.

Hario is a Tokyo-based heatproof glass maker best known for the V60 coffee dripper. Its “Clear” Tea Pot, sold in Japan as the フタなしティーポット (“lidless teapot”), drops two parts most teapots have: the lid and the strainer basket. What’s left is a glass pot, a clear PCT resin filter cap with a spout, and a silicone gasket. That makes it quick to rinse, but it also changes how you brew, since you can’t lift the leaves out. It comes in two sizes, the FNC-45-T (450 ml) and FNC-70-T (700 ml). They share the same cap design and the same 74 mm mouth, so the choice is mostly about how much tea you pour at once.

Specs from Hario USA, Hario’s global and Japanese product pages, and the FNC instruction manual (hario.com / global.hario.com). U.S. prices from Hario USA’s online store (hario-usa.com), checked October 31, 2026, when both sizes were listed as available. Hario’s Japanese product page lists both sizes at “about 300 g” including the box, while Hario’s Japanese online store lists 250 g and 330 g; Hario doesn’t publish the weight of the pot alone. Inch and ounce figures are our conversions.

Key differences at a glance

  • Capacity: 450 ml vs 700 ml (about 15.2 vs 23.7 fl oz), so the FNC-70-T holds about 55% more.
  • Size: 123 mm vs 144 mm tall (4.8 vs 5.7 in) and 130 mm vs 144 mm wide.
  • Fill marks: one dot at 300 ml on the 450 ml pot; dots at 400 ml and 600 ml on the 700 ml pot (from Hario’s manual drawings).
  • Price: $27.50 vs $33.50 at Hario USA, $6 more for the larger pot.
  • Same on both: lidless filter-spout cap in PCT resin, removable silicone gasket, 74 mm mouth, heatproof glass made in Japan, dishwasher safe, microwave safe (pot only), no stovetop use.

1. Capacity: How Many Cups per Pot?

Hario lists “practical capacity,” the amount the pot holds in normal use: 450 ml for the FNC-45-T and 700 ml for the FNC-70-T. Hario doesn’t give a cup count, so here is our math for two common cup sizes:

Pot Capacity 8 oz cups (our math) Japanese 150 ml cups (our math)
FNC-45-T 450 ml / 15.2 oz About 2 About 3
FNC-70-T 700 ml / 23.7 oz About 3 About 4 to 5

Our calculation from Hario’s practical capacity. Actual servings depend on your cups and how much room the leaves take up.

Size matters more with this teapot than with most. In a teapot with a removable basket, you can lift the leaves out when the tea is ready. In the Clear Tea Pot, the leaves stay in the water until you pour, and Hario’s manual says simply to pour the tea once it has steeped. A Japanese buyer on Hario’s store noted that if you don’t finish the pot, the tea gets too strong, so they brew only as much as they need each time. So the best size is the one you can pour out completely, into cups or a separate server, in one round:

  • FNC-45-T (450 ml): one large mug or two smaller cups, or tea for one person at a desk.
  • FNC-70-T (700 ml): tea for two or three people, or one person who wants a full serving of iced tea poured over a glass of ice.

You don’t have to fill the pot to the top. The fill dots help with smaller batches: 300 ml on the 450 ml pot, and 400 ml or 600 ml on the 700 ml pot.

2. How the Lidless Filter Spout Works

Both sizes use the same three-part design, according to Hario’s instruction manual:

  1. Filter with spout: a clear PCT resin cap with fine filter holes and a pouring spout. Hario says PCT is BPA-free, heatproof and impact resistant.
  2. Gasket: a silicone ring that fits onto the cap. Hario’s manual says to put it on with the small circle mark facing up.
  3. Glass pot: the body, with a handle.

To brew, Hario says to put tea leaves in the pot, add hot water, then press the cap firmly onto the top so it isn’t loose, with the spout set 180° from the handle (straight across). When the tea is ready, pour it. Hario USA also mentions sachets (tea bags) as an option. Because the cap stays on when you tilt the pot, Hario says you can pour easily with one hand.

Hario gives one pouring tip in the manual: pour slowly, because pouring too fast can make leaves float up and clog the spout. Hario’s global feature page also says the large pot lets leaves unfold easily, since no strainer gets in the way.

3. Size and Storage

The FNC-45-T measures 130 x 100 x 123 mm (5.1 x 3.9 x 4.8 in), and the FNC-70-T measures 144 x 120 x 144 mm (5.7 x 4.7 x 5.7 in). Both have a 74 mm (2.9 in) mouth, so the larger pot gets its extra room from a taller, wider body rather than a bigger opening.

Hario publishes weight only with the box. Its Japanese online store lists 250 g for the 450 ml and 330 g for the 700 ml. A Japanese tea blogger weighed the 450 ml pot with its cap at about 193 g. Either way, both are light for teapots because they have no metal strainer.

4. Cleaning, Microwave and Heat Limits

  • Dishwasher: Hario’s manual says the product is dishwasher safe.
  • Fewer parts: Hario says all parts can be washed and the rubber seal comes off. To clear leaves from the filter, Hario says to just pour water over it.
  • Microwave: Hario’s global page says only the glass pot is microwave safe, so take the cap off first.
  • Heat: the glass handles a temperature difference of up to 120°C (216°F), the PCT cap is heat resistant to 100°C (212°F), and the silicone gasket to 180°C (356°F). Not for stovetop or open flame.
  • Care tips from the manual: don’t leave the resin parts soaking in household bleach for a long time, and wash soon after use, because silicone can pick up the color and smell of strongly colored or scented food and drinks.

Hario’s Japanese online store told a customer that the gasket isn’t sold as a separate part. We didn’t find it listed as a spare part on Hario USA’s store either (October 31, 2026), so treat the gasket as part of the pot.

5. Price and Alternatives

At Hario USA, the FNC-45-T is $27.50 and the FNC-70-T is $33.50, and both were listed as available on October 31, 2026. That works out to about $1.81 per fl oz for the 450 ml and $1.41 per fl oz for the 700 ml. If you often brew for two, the 700 ml gives you more tea for $6.

If you’d rather be able to lift the leaves out, look at a teapot with a removable strainer. Hario’s ChaCha Kyusu Maru ($21.50 to $25.50 at Hario USA) has a stainless steel basket, and KINTO’s UNITEA One Touch Teapot pushes the leaves out of the water with a button. See our ChaCha Kyusu Maru 300 vs 450 vs 700 and KINTO UNITEA One Touch 460ml vs 720ml guides.

Who Should Buy Which?

Choose the Hario FNC-45-T (450 ml) if you:

  • Usually drink tea alone or with one other person
  • Want to pour the whole pot right away, so the leaves don’t over-steep
  • Have little shelf space (123 mm / 4.8 in tall)
  • Want the lower price ($27.50)

Choose the Hario FNC-70-T (700 ml) if you:

  • Brew for two or three people at once
  • Make iced tea and want room for a full serving to pour over ice
  • Want the 400 ml and 600 ml marks for different batch sizes
  • Want the better price per ounce for $6 more

A View from Japan

In Japan, Hario sells this pot as the フタなしティーポット・クリア, which translates to “lidless teapot, clear.” The Japanese page describes it as “a direct filter that’s easy to pour from” and says putting the filter into the PCT resin spout means fewer parts and easier handling. Hario’s Japanese specs match the U.S. listing, with suggested retail prices of ¥2,530 for the 450 ml and ¥3,080 for the 700 ml, tax included.

Hario says the glass is “HARIO Glass®,” its heatproof glass made from natural materials at its own factory in Japan, and the manual lists the glass and spout as made in Japan and the gasket as made in Vietnam.

Japanese reviewers often praise how easy it is to clean: with no strainer basket, they say a quick rinse clears the filter, and buyers on Hario’s store like that there are few parts to wash. They say the leaves open up well in the roomy glass pot, that the fine filter keeps leaves out of the cup, and that it is light and pours with one hand. One buyer of the 700 ml liked that the cap has an opening for adding more hot water without taking it off. On the downside, a tea blogger found that pouring fast or using fine deep-steamed sencha clogs the filter so the last of the tea trickles out slowly, and that spent leaves cling to the inside of the pot and need to be rinsed out rather than tipped out. One buyer noted that tea left in the pot gets too strong, and another said the gasket wore out after about three years, which matters because Hario Japan doesn’t sell it separately.

Hario Clear Tea Pot 450ml vs 700ml: Frequently Asked Questions

Should I get the Hario Clear Tea Pot 450ml or 700ml?

Get the FNC-45-T (450 ml, $27.50 at Hario USA) if you brew for one or two people, about two 8 oz cups per pot. Get the FNC-70-T (700 ml, $33.50) if you brew for two to three people or want about three 8 oz cups at once. Because the leaves stay in the pot, pick the size you will pour out in one go; tea left sitting on the leaves keeps getting stronger.

Does the Hario Clear Tea Pot have a lid?

No. Hario’s Japanese name for it is “lidless teapot.” Instead of a lid, a PCT resin filter cap with a built-in spout fits into the top of the glass pot with a silicone gasket. You put loose tea in the pot, add hot water, press the cap on, and pour through the filter.

Is there a strainer basket?

No. The leaves float freely in the glass pot, and the filter is built into the spout cap. Hario says the large pot lets leaves unfold easily because no strainer gets in the way. The trade-off is that you can’t lift the leaves out to stop steeping.

Is the Hario Clear Tea Pot dishwasher safe?

Yes. Hario’s manual says the product is dishwasher safe, and the gasket comes off for washing. Hario warns that soaking the resin parts in household bleach for a long time can shorten their life.

Can I put the Hario Clear Tea Pot in the microwave or on the stove?

Only the glass pot can go in the microwave, without the filter cap. It is not for stovetop or open-flame use. The glass handles a temperature difference of up to 120°C (216°F), and the PCT resin cap is heat resistant to 100°C (212°F), so boiling water is fine.

Can I make cold brew or iced tea in it?

Yes. Hario lists iced tea in summer as a use. A Japanese tea blogger also found the tall pot handy for cold-brewed green tea with plenty of ice.

Does it work with fine Japanese green tea?

It works, but pour slowly. Hario’s manual says pouring too fast can let leaves float up and clog the spout. Japanese and U.S. reviewers say very fine fukamushi (deep-steamed) sencha pours slowly through the filter. Larger-leaf teas like hojicha pour more easily.

Is the Hario Clear Tea Pot left-handed friendly?

Yes. Hario sets the spout 180° from the handle, straight across, so it pours the same way in either hand. A Japanese buyer on Hario’s store mentioned this as a plus for left-handed users.
