Yupuru Nirasaki (Nirasaki Health & Community Center)
ゆ〜ぷるにらさき（韮崎市健康ふれあいセンター）
A city-run day-trip onsen facility next to Michi-no-Eki Nirasaki along Route 141 in Nakada-machi, Nirasaki. The spring - 44.5°C at the source, pH 8.3, a sodium bicarbonate-chloride spring (hypotonic, weakly alkaline, high-temperature) - is clear with a faint sulfur scent and a silky, thick feel. The bright stone-built large bath has pressure jets, bubble baths and a lying bath, joined by an open-air bath, two saunas (dry and mist, switching sides weekly) and a cold bath. Best of all, the admission fee also covers the heated pool with a 45-metre lazy river, jacuzzi and children's pool. Its glass dome is a landmark; there is a free grand lounge plus paid private rooms. About 8 minutes by car from the Nirasaki IC on the Chuo Expressway, with free parking for 70 cars.

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.
