The Best Kyusu Teapot for Loose Leaf Tea
Researched by Johnny Alto · Published July 29, 2026
Short answer: The best kyusu teapot for loose leaf tea is the Hario ChaCha Kyusu Maru Tea Pot (450ml, Glass). For a first real kyusu, glass is the forgiving choice: you can see the tea's color to judge steep strength, it does not hold odors or flavors the way porous clay does so it is neutral across green, oolong, and herbal, and Hario's large stainless mesh basket gives the leaves room to expand for full extraction, in heatproof borosilicate that is dishwasher-safe, with the 450ml size suiting 2 to 3 cups. The main things to weigh are size, glass vs clay, strainer, and handle.

Hario ChaCha Kyusu Maru Tea Pot (450ml, Glass)
For a first real kyusu, glass is the forgiving choice: you can see the tea's color to judge steep strength, it does not hold odors or flavors the way porous clay does so it is neutral across green, oolong, and herbal, and Hario's large stainless mesh basket gives the leaves room to expand for full extraction, in heatproof borosilicate that is dishwasher-safe, with the 450ml size suiting 2 to 3 cups. The honest limits: glass retains far less heat than clay, which purists argue matters for coaxing sweetness out of sencha, the mesh is coarser than the ultra-fine ceramic strainer of a traditional Tokoname pot so very fine deep-steamed leaves can slip through, and glass is more breakable than ceramic.
View on Amazon Editorial illustration.A kyusu is the Japanese side-handle teapot built for the way green teas like sencha and gyokuro are actually brewed: short, repeated infusions with a wide, fine strainer that lets small leaves open fully and pours clean without a separate infuser basket. The side handle gives you control for the quick pours these teas need. This is for someone moving past bagged tea or a generic infuser mug, deciding between easy-clean glass and traditional heat-retaining clay. Here is the pick, a clay upgrade, and what to check.
How do the best options for kyusu teapot for loose leaf tea compare?
| Pick | Product | Why it makes the list |
|---|---|---|
| Top pick | Hario ChaCha Kyusu Maru Tea Pot (450ml, Glass) | For a first real kyusu, glass is the forgiving choice: you can see the tea's color to judge steep strength, it does not hold odors or flavors the way porous clay does so it is neutral across green, oolong, and herbal, and Hario's large stainless mesh basket gives the leaves room to expand for full extraction, in heatproof borosilicate that is dishwasher-safe, with the 450ml size suiting 2 to 3 cups. |
| Traditional clay upgrade | Azmaya Tokoname Black Unglazed Kyusu (300ml) | Authentic unglazed Tokoname clay retains heat and is prized for smoothing sencha over time, a genuine artisan pot. It is expensive, porous (best dedicated to one tea type), and hand-wash only. |
| Authentic mid-range | Yamakiikai Tokoname Side-Handle Kyusu (280ml) | Real Tokoname-ware with a built-in ceramic strainer at a friendlier price than Azmaya. It is a smaller 280ml capacity, and the glazed finish is less purist than raw clay. |
| Best budget entry | TEANAGOO Japan Kyusu Side-Handle Teapot | The cheapest way to try the side-handle format, with a removable infuser and easy cleanup. It is mass-produced ceramic (not artisan Tokoname clay) and the removable steeper is less elegant than a true integrated strainer. |
What should you look for in kyusu teapot for loose leaf tea?
A few things separate a good kyusu teapot for loose leaf tea from a frustrating one: size, glass vs clay, strainer, and handle. Weigh these before you buy.
- Size: 300 to 450ml (2 to 3 cups) is the sweet spot for green tea's multiple short infusions; 700ml exists but is large for the style.
- Glass vs clay: glass (Hario) is neutral-tasting, easy-clean, dishwasher-safe, and lets you see the brew; unglazed Tokoname clay retains heat and can mellow sencha but is porous, best dedicated to one tea, and hand-wash only.
- Strainer: look for a wide built-in mesh or ceramic strainer integral to the pot, not a small drop-in basket, so fine leaves do not clog or slip through.
- Handle: a true kyusu has a side handle (about 90 degrees from the spout) for controlled one-handed pours, the defining feature versus a Western rear-handle pot.
Glass or clay?
The kyusu decision comes down to glass versus clay, and both are valid. Glass is the neutral, practical choice: it is nonporous so it never carries flavor from one tea to the next, it is dishwasher-safe, and you can watch the liquor color to judge when to pour, which makes it forgiving for a beginner brewing across greens, oolongs, and herbals. Unglazed Tokoname clay is the traditional choice: it retains heat far better, which purists say coaxes more sweetness out of sencha, and over time it seasons to the tea, but it is porous so you dedicate it to one type, and it is hand-wash only. Either way, the mark of a real kyusu is a wide built-in strainer that lets fine Japanese leaves fully open, and a side handle for quick, controlled pours.
