Hakone-Yumoto Kappa Tengoku

箱根湯本温泉 かっぱ天国

Directly behind Hakone-Yumoto Station, a 3-minute climb up steps: a rustic wooden bathhouse with its own free-flowing spring and an open-air bath. Shōwa-era charm and surprising quiet for a station-front spot. Private indoor bath (¥1,000/45 min + entry) and a ¥200 footbath.

Why go

  • Free-flowing open-air bath 3 min from the station
  • Shōwa-retro wooden bathhouse
  • Walk-in private bath available

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.
