Hakone-Yumoto Kappa Tengoku
箱根湯本温泉 かっぱ天国

On the hill right behind the station — Hakone’s most casual soak
Kappa Tengoku, founded in 1955, sits on the hill directly behind Hakone-Yumoto Station, a three-minute climb up the steps. Its two private springs flow 100% free of dilution or reheating, and the pH 9.2 alkaline water leaves skin silky. There is just one open-air bath per gender — simple, but at ¥900 it is among Hakone’s cheapest, and three minutes from the platform makes it perfect for a quick dip before the train. A paid foot bath sits beside the entrance.
Tips & cautions
- With no indoor bath, the rotenburo can feel lukewarm in winter — stay in a while and you warm up.
- The Tozan railway passes above the bath; train sounds are part of the charm (or not).
- Lockers ¥100 (refunded). Leave big suitcases at the station — there are stairs.
- The private bath is a bargain at ¥1,000 for 45 min and popular with families and couples; sign up on arrival.
- Busy on holiday evenings; around noon is quieter.
Getting there
About 3 min on foot from Hakone-Yumoto Station (Tozan line / Odakyu Romancecar) up the stairs behind the station (Yumoto 777). Parking for ~30.
Before you go
- No official tattoo policy is published — ask at reception.
- Last entry is 30–60 minutes before closing.
