In a Japanese style lodging place, you will enjoy@wearing YUKATA (simple cotton kimono) and an OBI (sash ).
You can wear YUKATA at dinner, or going to bath, even outside of the ryokan.
Looking at your YUKATA, people will know at which ryokan you are staying, and they will welcome you to the town.

You can have HANTEN (half-coat) over YUKATA if you feel cold,
orTANZEN (full-length over-coat),
or both.
I'd be happy to help you change.
We have large size YUKATAs.
