Shimobe Onsen Koyokan
下部温泉 甲陽館
A small inn of Shimobe Onsen, where the tradition of long healing stays continues, and a bath alone can be taken in the daytime without staying overnight.

Why go
- Day bathing at 800 yen in a healing-spring town
- Received from 9:00 in the morning
- A course with a rest room is also offered
A daytime bath in a healing-spring town
Koyokan is a small inn of ten rooms that keeps the unhurried healing-spring culture of Shimobe intact. Day bathing is received from 9:00 in the morning, so arriving early in the spa street wastes no time. An hour is enough for the bath alone, which makes it easy to fit between a walk and lunch.
Other ways to use an inn's bath
Most inns of Shimobe Onsen take day bathers, though prices and hours differ from one to another. The bath alone commonly costs 500 to 1,000 yen, rising to around 2,000 yen when a rest room is added. Each inn refuses on some days depending on its business, so if a particular one is wanted, a call the day before is best. The town-run Shimobe Onsen Kaikan almost never closes and serves as a good alternative.

Fujiyama Onsen
Next to Fuji-Q Highland, with one of Japan's largest all-timber bath halls. Price includes loungewear and towels, so come empty-handed. Free shuttle from Fujisan Station. Prices revised April 2026.
Hottarakashi Onsen — Acchi-no-yu
On a mountainside above the Kofu basin, a spectacular open-air bath with Mt. Fuji and the city lights in view. It opens 'one hour before sunrise', so people arrive in the dark to watch dawn break over Fuji from the water. Of the two bathhouses, 'Acchi-no-yu' is the larger with the better view. ¥900. The deep-fried hot-spring egg from the food stall is a must. Ten minutes by taxi from Yamanashi-shi Station; a feasible day trip from Tokyo.
Yamanakako Onsen Benifuji no Yu
Three minutes by car from Yamanakako IC, a day spa with Mt. Fuji rising straight ahead of the open-air bath. Highly alkaline (pH 10.3) yet gentle on the skin. Two open-air baths—stone and cypress—plus a lie-down bath, jets and sauna for ¥900. On winter weekends (Dec–Feb) it opens at dawn so you can watch the peak blush red at sunrise, the 'benifuji' of its name. 30 minutes from Fujisan Station on the Fujikko-gō loop bus.
