Yamanashi · Hottarakashi Onsen (Yamanashi)
Hayabusa Onsen
はやぶさ温泉
A day-use bathhouse among the vineyards and peach orchards of Makioka in Yamanashi city, cherished by onsen fans as one of the prefecture's finest 'fresh from the source' springs. About 500 litres a minute of 42°C alkaline simple water wells up naturally and goes straight into the tubs — no heating, no dilution, no recirculation — so fresh water overflows constantly at the spout. The feel is silky; from the cypress indoor bath and the rock open-air bath you can sometimes see Mt Fuji across the Kōfu basin. Adults ¥700 for up to two hours, children ¥500 (four hours with tatami-hall rest ¥1,300; all day ¥1,800); open 10:00–21:00 (last entry 20:15), closed Tuesdays and the New Year period. A restaurant serves hōtō noodles and tempura, and Erin-ji temple and the local wineries are close. About 25 minutes by car from Katsunuma IC or 15 minutes by taxi from JR Yamanashi-shi Station.

Five hundred litres a minute of 'fresh-flowing source' — the finest water in Yamanashi, say the connoisseurs
Hayabusa Onsen is a day-use hot spring opened in 1994 at the foot of the mountains on the north side of the Kofu basin in Makioka, Yamanashi city, amid spreading peach and grape orchards. Fifteen minutes by car from the famous Hottarakashi Onsen, it is its polar opposite in character — a place that competes on water alone rather than views or facilities. Its pride is 'fresh-flowing source': a highly alkaline simple spring of around pH 9.95 gushing at a generous 500 litres a minute, run straight into the tubs with no dilution, heating or recirculation whatsoever, so that water overflows ceaselessly in both the cypress indoor bath and the rock rotenburo. The 'toro-toro' slip on the skin and the fine bubbles that cling to the body are proof of freshness, and at a comfortable 40–41°C you can soak for an hour, which is why Yamanashi's onsen fans have long rated it 'the finest water in the prefecture'. Prices start at ¥700 for a two-hour bath, with a cure-style tier of ¥1,300 for four hours including the 40-mat tatami hall and ¥1,800 for a full day; the restaurant's hoto (Yamanashi's miso-simmered flat noodles) and the entrance shop's seasonal fruit — peaches, grapes, persimmons — and bottled source water are popular. On clear days the summit of Mt Fuji shows from the rotenburo, and peach-blossom time (early April, when the basin turns pink) and the autumn grape and wine season are the best. Closed Tuesdays; 1 h 40 min from Shinjuku by limited express plus 10 minutes by car, or 25 minutes from Katsunuma IC — the classic course pairs it with the Koshu wineries or with Hottarakashi for a 'water versus view' comparison.
Overflowing water in the cypress bath and rock rotenburo, and a cure-style day in the hall
At the entrance of the modest building on the road between orchards is a stall selling seasonal fruit and vegetables; at reception choose two hours (¥700), four hours (¥1,300) or a full day (¥1,800), with towel sets for rent at ¥210. The layout is simple — one cypress-lined indoor bath and one rock rotenburo through the door — but in both the source gushes from the spout and spills over the entire rim, bringing '500 litres a minute' to life. Wash (shampoo provided) and step into the indoor bath: the mild 40–41°C water wraps the skin like silk, and after a minute or two fine bubbles gather on arms and legs, the mark of a fresh, reducing spring. The spot right beside the spout is freshest and slightly hotter, so connoisseurs favour it. The rotenburo is a plain pool ringed by rocks and trees, but on clear days the summit of Fuji shows straight ahead in the distance, and in spring the basin below is carpeted pink with peach blossom. The temperature allows long bathing — two or three sessions of 20–30 minutes — and if you skip the rinse the slickness lingers. A sip from the drinking spout is soft and faintly slippery. On the four-hour or full-day plan, claim a spot in the 40-mat hall upstairs (or a reserved private room) and spend a cure-style day of bath, hoto lunch, nap and bath again — the proper way to use this place, as local seniors do on weekday afternoons. The restaurant (last order 20:00, break 14:00–15:00 on weekends and holidays) serves hoto, soba, tonkatsu sets and Yamanashi's 'torimotsu-ni' chicken giblets. Weekend afternoons fill with people returning from Hottarakashi, so weekdays or the weekend opening hour are most comfortable; there is no sauna or bedrock bath — know that this is a place to focus on 'water and rest'.
Practical details and a Koshu fruit-and-wine route
Hours are 10:00–21:00 (last entry 20:15, restaurant last order 20:00), closed Tuesdays (check holiday operation) and 29 December to 3 January; two hours ¥700, four hours ¥1,300, full day ¥1,800 (children ¥500/¥800/¥1,100), towel set ¥210, parking free. Access is 10 minutes by car from Yamanashishi Station (few buses), 1 h 40 min from Shinjuku by Kaiji limited express, or 25 minutes from Katsunuma IC / 2 hours from Tokyo by car. Suggested routes: (1) a Koshu wine day — Katsunuma-Budokyo Station, tastings at two or three wineries (Chateau Mercian, Grace and others; drivers abstain), Erin-ji (Takeda Shingen's family temple and garden), Hayabusa Onsen, then the limited express home from Yamanashishi; (2) 'water versus view' — Hayabusa in the morning (water), lunch at Fuefukigawa Fruit Park, Hottarakashi Onsen before sunset (view, 'Atchi-no-yu'), then the night lights; (3) peach blossom (early April) — a drive through the orchards of Misaka and Ichinomiya, then the pink basin from Hayabusa's rotenburo; (4) autumn harvest — grape and persimmon picking (August–November), a bath, fruit from the shop; (5) a Nishizawa Gorge trek (foliage late October, 30 minutes by car) followed by a post-hike soak. Notes: no sauna or bedrock bath; the two-hour plan incurs a surcharge if overrun; the restaurant breaks 14:00–15:00 on weekends and holidays; public transport is poor; check the tattoo policy. For those who choose onsen by 'freshness of water', Hayabusa is the first name in Yamanashi, and comparing it with Hottarakashi's view in a single day lets you experience both poles of Yamanashi bathing at once.

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.
