From the Edo period to the present, Japanese teapots have evolved through a fusion of functionality and design. During the Edo era, teapots were ingeniously designed with handles that allowed for easy pouring while retaining the tea leaves inside, making tea an integral part of popular culture and leading to the widespread use of teapots. With the modernization of the 20th century, traditional craftsmanship faced new challenges, yet the production of teapots continued. Throughout history, teapots in various shapes and materials have been created, each respecting past traditions while developing their own unique expressions. Our approach has been to think about how to evolve teapots in a time when the habit of drinking tea is in decline. '360 KYUSU' is a teapot conceived from the perspective of a product designer, combining the wisdom learned from history and tradition with modern high-function materials and features.
