【Why Tokoname Kyusu?
The Secret to the Perfect Green Tea】
900 Years of Heritage
Tokoname-yaki is one of Japan’s most renowned pottery traditions. Each piece represents centuries of craftsmanship.
Scientific Flavor Enhancement
Made from iron-rich clay, these teapots react with tea tannins to :
・Reduce bitterness
・Enhance natural sweetness (Umami)
・Create a smoother mouthfeel
Masterful Precision
Each lid is handcrafted for a "seamless fit," ensuring a perfect pour without a single leak. The more you use it, the more the clay develops a beautiful natural sheen (patina).
【Care Instructions】
・For daily cleaning, please wash with water only, without using detergent.
・Make sure the tea strainer is thoroughly dried to prevent water from collecting inside.
・If tea stains are difficult to remove, soak the teapot overnight in a solution of kitchen bleach diluted to about 1%. After soaking, rinse thoroughly with boiling water.
※Please note that items may sell out as we share inventory with our store. We appreciate your understanding.
