Made in Japan from Tatsuchi, the natural clay Japanese potters have worked for centuries, thrown and finished by hand and fired to a deep, even black. Small variations in colour and surface come out of the kiln rather than the mould, so no two pots are quite the same.

Warm the pot, add 5 g of leaf and 150 ml of water at around 70 °C, and steep for one to two minutes. Pour it out to the last drop so the leaves are never left standing in water. Because the pot is small the leaf-to-water ratio stays high, and the cup comes out noticeably more intense than the same tea brewed in a larger kyusu.

A light glaze rather than a full one: enough to keep the inside neutral and easy to clean, while leaving something of the clay's own texture on the surface. The dark body hides tea staining, so it ages well even with daily use.

210 ml puts this on the smaller side, which is exactly the point — less water around the same weight of leaf means a denser, more concentrated infusion. It is the right size for brewing on your own or for two small cups, and for teas you want to taste closely rather than drink by the potful.

A built-in stainless-steel filter sits inside the body across the spout, holding back even fine leaf without getting in the way of the water. The side handle keeps your hand clear of the heat and lets you pour with a simple turn of the wrist.

For us, tea is more than a beverage—it’s a way of life. We’ve spent years visiting tea farms across Japan, tasting teas with the people who grow them and building lasting, direct relationships. We believe this is the most sustainable way to source tea: fewer intermediaries, greater traceability and a closer connection between farmer and drinker.

Every tea is 100% pesticide-free and carefully selected for its taste, origin and craftsmanship. Whether you’re discovering Japanese tea or comparing cultivars and terroirs, you’ll find honest tasting notes, precise brewing guidance and real support to help you get the best from every cup.

•
Built-in Filter

Part of the pot, not a basket. Water moves freely around the leaves.

•
Side Handle

Set at a right angle to the spout, so you pour with a turn of the wrist.

•

A broad, shallow body gives the leaves room to open fully.

How to Use
a Kyusu Like a Pro

A kyusu is built for short, repeated infusions rather than one long steep. Warm it, fill it only part way, and pour it out completely every time — the leaves stay in the pot and the same measure will give you two or three cups.

Nio teas has been my favourite place to purchase good quality teas for a while now, and still they never disappoint me. Their teas are excellent quality, however, I’d like to give more attention to customer service - Nio team has been very kind and helpful each time I had any sort of problem. Their customer service never disappoints, they are very attentive and quick in responding to any queries, hence why I’ve been a loyal customer for a while now.

My favorite vendor for Japanese organic loose leaf green teas. They are sourcing some of the best organic teas out of Japan and supporting family farmers and the growing organic tea industry as a whole.I have ordered from every vendor for years and Nio consistently has the best prices and selection overall. They provide top notch customer service and fast shipping as well. Highly recommended 🍃

FAQ

Before you order

Shipping is free once your order passes the threshold for your country — USD 54.99 · EUR 54.99 · GBP 44.99 · CHF 49.99 · CAD 74.99 · DKK 399 · SEK 599 · PLN 229 · CZK 1,290. Everywhere else it's the equivalent of USD 54.99, converted automatically. Below the threshold a flat rate applies, always shown at checkout before you pay.

We ship from warehouses in the US, the EU and Japan — whichever is closest to you. US and EU orders arrive in 4–12 business days; the handful of countries served from Japan take around 10. Business days count from dispatch rather than from when you order, and exclude weekends and public holidays. You'll get a tracking number by email the moment your parcel leaves the warehouse.

We only buy from fields grown without pesticides or chemicals. We ask each farmer directly how they manage their land, visit the plantation and processing facility ourselves, taste every harvest before committing, and check that the biodiversity around the fields is alive. Small family farms don't always carry paperwork — so we verify it in person instead.

Japanese green tea covers an enormous range, and choosing online isn't easy. If you've tried yours and it isn't for you, email info@nioteas.com within 30 days with your order number and a line on what you didn't enjoy. We'll send a different tea of equal or lower value, free. Nothing to post back — keep it, share it, or try brewing it cooler. Once per order.

Email info@nioteas.com within 30 days with your order number and a photo. We'll approve it, cover the return postage with a prepaid label or a reimbursement, and refund you — no restocking fee. Refunds go to your original payment method within 2 business days of the return reaching us; your bank may take another 5–20 to show it.

Unopened items in their original packaging can be returned within 30 days. Tea is sealed for hygiene, so opened packs can't come back — but the swap above covers exactly that situation. Return postage is yours unless the item arrived damaged, defective or incorrect.

Orders to the US and EU ship domestically from our local warehouse, so there's no customs charge and no duty. A small number of destinations are served from our Japan warehouse, where your own customs authority may apply import duty, VAT or a carrier handling fee on delivery. Those are set by your country, not by us. Ask before you order and we'll help you check.

info@nioteas.com or +41 79 751 83 88. We reply within 2 business days, usually much sooner, in English.
