This is a 59×63cm zabuton which is once-dominant size. As the style of dwellings shifted to the Western style from the Japanese style, a little smaller meisenban became the dominant zabuton size. Nowadays, a hattanban is still used in a traditional Japanese house which has lots of Japanese-style rooms and also used for guests attending a Buddhist memorial service or celebration.
This zabuton is characterized by its capability of reducing stress to legs and feet even when sitting on it for a long time. ‘Hattan’ is the name of the woven silk fabric which was used for a zabuton in an earlier time.
