About
Ryusen is a bathhouse in Senami Onsen, a hot spring town on Niigata's Sea of Japan coast, built mainly for day trips rather than long stays. The big open-air bath is split into several separate tubs, including Awa-yu (泡湯), a bubbling bath, and Taki-yu (滝湯), fed by a small falling stream, plus a bright indoor bath lit from above. The water comes from the facility's own sodium chloride spring, faintly cloudy with a seawater smell, and it leaves skin feeling smooth and a little slippery, likely from being so close to the coast. There's also a reservable family bath for soaking without other guests around, and a small guest wing for those who want to stay the night. No sauna here, just a straightforward soak.
