A tatami room has no special use. It serves as a bedroom at night, a work room during the day, and a dining or relaxation room in the morning and evening. The tatami room is especially important as a place to practice traditional Japanese arts such as ikebana and tea ceremony, and even in a completely Westernized house or apartment building, treasured works of art and pottery are sometimes displayed up on small boards that look like miniature tatami mats, with the same woven surfaces and colored borders. The alcove was originally considered a sacred place for the enshrinement of Buddha images, but later on, they began to place seasonal picture scrolls and special occasion items. Later, they began to contain seasonal picture scrolls and special occasion scrolls, as well as flowers and incense burners. On average, the tokonoma is about the size of a tatami mat.
