A Kyusu is a traditional Japanese teapot, specifically designed for brewing green tea. Typically made from clay or ceramic, it features a side handle and a spout that allows for precise pouring. The design helps to enhance the flavor of the tea by allowing the leaves to expand fully during steeping. Kyusus often come with a built-in strainer, which prevents tea leaves from entering the cup. They are available in various styles and sizes, reflecting regional craftsmanship. Using a Kyusu is an integral part of the Japanese tea ceremony, emphasizing the importance of tea in Japanese culture.
