Hot spring

Hakone is home to twenty hot springs that are known for their therapeutic effects. Yumoto, which supplies our semi-open baths, is particularly famous. Each bath hall offers a view of Mt. Yusaka and echoes with the babbling of the nearby Sukumo River.

  • Bath halls are semi-open to provide guests with a more naturalistic bathing experience.
  • Although one area of the halls has been set aside for washing, guests are encouraged to wash themselves in their rooms beforehand during colder seasons.

Yuagari Lounge

Located between the men's and women's bath halls, the Yuagari Lounge allows guests to cool off after a bath while sipping on a refreshing beverage inspired by the local culture.


Same day reservations available at the front desk.

KAI Cultural Discovery

Every KAI establishment offers a selection of free activities designed to introduce guests to Japan's regional cultures. At KAI Hakone, activities revolve around a style of parquetry that has traditionally been practiced in Hakone. The craft is known for its colorful patterns that make use of the area's diverse tree population. Activities include tea sessions, storytelling, and even crafting workshops.

Parquetry chaya

Travelers in the past would stop at teahouses known as chaya to rest and exchange information. This activity recreates that scene with refreshments served on or in Hakone parquetry.

Secrets of parquetry

A pictorial storytelling session is held everyday to offer guests an enjoyable introduction to Hakone parquetry.
