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.

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.
