About
What this guide is—and isn’t
OnsenCheck Japan is a small independent, source-based guide to a specific Hakone booking question.
Why it exists
“Private bath,” “open-air bath” and “in-room onsen” can describe different purchases. We organize the hotel’s own room statements so a traveler can check the exact category before paying.
What we can claim
We link to the property or provider page and name details we could not verify. We do not claim to have personally stayed at or photographed every ryokan. Location photographs on this site show Hakone scenery, not any listed room.
Who takes the booking?
The hotel or tour provider sets current inventory, price, payment, changes and cancellations. OnsenCheck Japan has no checkout or traveler account.
