The cylindrical container in a ryokan guest room that holds the tea set (teapot and teacups) is called a "chabitsu." It's a tool for storing the teapot, teacups, tea caddy, saucers, and tea waste container together to keep them dust-free. This one was purchased in the Showa era and kept by my grandmother.
