Kurokawa Onsen, Kumamoto

Kono-yu Ryokan

Every room has a private open-air or semi-open-air bath; compare the specific room before booking.

Why it may fit

  • Worth comparing if you want a private bath, a quiet setting and time to stay in. If you expect to walk around the onsen town often, check the slope and shuttle arrangements first
  • Published bathing information lists general indications including sensitivity to cold, poor peripheral circulation and dry skin. This is not a treatment claim

Trade-offs to check

  • Handrails, seating and temperature controls vary by room; ask about the specific room plan. The sloping approach can be harder than the map distance suggests
