急須 (kyūsu) is a traditional Japanese teapot used for brewing green tea, particularly 煎茶 (sencha). It typically has a small spout, a handle, and a lid, designed to allow for precise pouring and steeping. The material is often clay or ceramic, which helps maintain the tea's temperature and flavor. The design of a 急須 can vary, with some featuring intricate patterns or glazes. It is an essential item in Japanese tea culture, reflecting the importance of tea ceremonies and the appreciation of 茶道 (sadō), the way of tea. Using a 急須 enhances the experience of enjoying tea, making it both a practical and aesthetic object.
