Tokaikan is a former ryokan and onsen (hot springs), facing the river Matsukawa in Ito town, Shizuoka Prefecture. Ito is a popular onsen resort area and in ancient times it was known as hot spings good for eyes.
Tokaikan was operated from 1928 to 1997. The three-story building was constructed by master Japanese craftsmen with high quality wood and it is one of the few remaining onsen built of wood during the early Showa Period. It is designated as a cultural property of Ito and nowdays it is a sightseeing spot. The baths are open for bathing on weekends and public holidays and can be used by men and women at different times (women 13:00-14:45, 17:00-19:00 and men 11:00-12:45, 15:00-16:45),
In 2010 half of Tokaikan building was turned into a K’s House hostel.
Tokaikan is about 10-minute walk from Ito Station. You can reach Ito Station from Tokyo Station, in about 1 hour and 40 minutes with JR limited express train Odoriko.
