Japan’s onsen (thermal hot spring) tradition dates back thousands of years. Since the Edo Period, Nozawaonsen has been renowned for its thermal baths. Both a luxury and daily necessity, local hot springs serve the villagers as baths as well as sources of hot water for cooking.
Our private thermal onsen baths are fed with the highly valued Shinyu waters. The prized milky hues of the water evolve depending on the season and are known locally as ‘five colours water”. Our onsen waters are rich in various minerals, abundent with the highly sought-after floating yunohana (mineral water flowers), and especially beneficial to our overall well-being and health. Shinyu waters are recommended for skin and other conditions.
Our onsens are available “kashikiri” for private use. Please ask for availability if you would like to reserve some private time.
During peak occupancy periods, the onsens will be reserved for common use by all guests (usually from 4-6pm). During these periods, you will see signs outside designating each onsen for Male/Female use.
Residence Yasushi has gained “gensen kakenagashi” status for its onsen. This is a protected nomenclature, and is the gold standard for onsens in Japan; there is no higher.
Our nearest is the charming ShinYu-no-yu. It’s just two doors down from us. Rebuilt and reopened in December 2006, ShinYu resembles a mini O-yu (Nozawaonsen’s largest soto-yu). ⠀
Halfway down the little road between Residence Yasushi and Kumanoteara-yu, you’ll find Kamitera-no-yu.⠀This soto-yu was rebuilt about thirty years ago and features a relatively good changing room. Its waters are considered particularly good for healing skin lesions. Locals believe coming and soaking when you have cuts or burns or other skin lesions is specially beneficial. Any cooks who have had minor accidents preparing meals this week come on over!! These waters are fed off streams issuing from Asagama, and tend to look bluish green and quite hot - high 50 degrees C.
