An onsen on a beach where the waves can be heard
Senami Onsen is a spa on the Sea of Japan shore at Murakami, its inns lined up facing the water. Taikanso stands close to the water's edge, so you bathe with the sound of the waves. From the observation open-air bath at the top of 66 steps the horizon lies plain, and at sunset the light that reddens it fills the view.
A round of the Senami baths, open into the night
Senami Onsen has other baths in the spa besides this inn. The open-air bath Ryusen receives from 9:00 to 22:00 and this inn from 10:00 to 22:00, so a day can be used at length. Murakami is also known for salmon dishes, making it a spa where bathing and eating can be combined.

Yuzawa Onsen Egami Public Bath
A locals' public bath three minutes from the east exit of Echigo-Yuzawa Station, tucked into the shopping street. Indoor pool only, but the slightly hot, soft water that clings to the skin gets praise. Shampoo is provided and a towel set costs ¥400, so you can drop in empty-handed while waiting for the shinkansen. ¥600 since December 2025.
Tsukioka Onsen Bijin-no-izumi
Forty minutes by car from Niigata city, the communal bath of Tsukioka Onsen, which bills itself as the spring that 'makes you beautiful'.

Tsukioka Onsen Furinya
An hour by car from Niigata city, a ryokan in Tsukioka Onsen, famed for water that 'makes you beautiful'. Its emerald-green spring, among the most sulfur-rich in Japan, fills indoor and open-air baths, and day use runs late — 15:00–23:00 — so you can soak while the garden is lit up. ¥800 on weekdays (¥1,000 with towel), +¥200 on weekends and holidays. Combine with the free footbath and spring-source park in the village.
