Yamanashi · Hottarakashi Onsen (Yamanashi)

Hottarakashi Onsen — Acchi-no-yu

ほったらかし温泉 あっちの湯

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.

Yamanashi · Yamanakako OnsenTattoos: Ask ahead

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.

Yamanashi · Shimobe OnsenTattoos: Ask ahead

Shimobe Onsen Shimobe Hotel

The leading large ryokan of Shimobe Onsen in Yamanashi, the 'hidden bath' of warlord Takeda Shingen. Its hallmark is three springs of differing character (including the tepid original Shimobe water) served in eleven tubs, seven of them open-air — a mini bath-hopping circuit with streamside rotenburo and Shingen lore. Day use 11:00–15:00, ¥1,200; resting in the tatami hall is free, and lunch-and-rest plans start at ¥5,000. Irregular closures, so confirm ahead. Just 3 minutes on foot from Shimobe-Onsen Station on the JR Minobu Line — easy by rail, and a natural pairing with Kuonji temple on Mt Minobu, the Fuji River or a Lake Motosu / Fuji Five Lakes drive.
