If you've started exploring Japanese tea, you've probably come across the word kyusu. These traditional side-handled teapots are highly regarded by tea enthusiasts and are especially popular for brewing sencha, gyokuro, and other Japanese green teas.
But with so many options available online, how do you know if you're buying an authentic kyusu?
Look for Tokoname Clay
Tokoname is one of Japan's six ancient pottery regions and has been producing teaware for centuries. Authentic Tokoname kyusu are made using clay sourced from the Tokoname area in Aichi Prefecture.
Many are made from red clay, known as shudei, although black and natural clay varieties are also common.
Check the Filter
One of the defining features of a quality Tokoname kyusu is the built-in ceramic filter, often called a sasame filter. These clay filters allow tea leaves to open fully while preventing leaves from entering the cup.
While metal mesh filters are common, many tea enthusiasts prefer ceramic filters for a more traditional brewing experience.
Look for a Potter's Mark
Handmade Tokoname teapots are often stamped with the mark or signature of the artist or kiln. Names such as Gyokko, Tosen, Shoryu, and other established craftsmen are well respected among collectors and tea drinkers.
A potter's mark is usually a good indication that the teapot was produced by a recognised workshop rather than mass-produced.
Choose the Right Size
For most Japanese green teas, a kyusu between 180ml and 320ml works well. Smaller pots are ideal for gyokuro, while larger capacities are often preferred for everyday sencha.
Don't Focus Only on Appearance
Beautiful decoration is always a bonus, but the most important factors are clay quality, balance, pouring speed, and comfort in the hand.
A well-made Tokoname kyusu should pour smoothly and feel natural to use.
Final Thoughts
An authentic Tokoname kyusu can last for decades and often becomes more enjoyable with use. Whether you're new to Japanese tea or looking to upgrade your teaware collection, investing in a quality handmade kyusu can greatly enhance your tea experience.
