Welcome to Kohsinzuka

Old houses have many gaps, so they are cool in the summer but cannot protect against the cold in the winter.
Due to rising heating costs, we are unable to provide a comfortable stay for our guests, so we will be closed for the winter from mid-December to early March.
Reservations for early March to mid-December next year will be accepted starting in October of this year.

Koshinzuka Ryokan is a traditional Japanese house that is over 100 years old and located in Otsumago, a short distance from Tsumago-juku.
The hotel is surrounded by Nakasendo roads and mountain streams.
The traditional charcoal hearth is loved by many guests.
You can enjoy your evenings by eating and chatting with guests around the warm hearth.
Please enjoy your time in this rural hideaway.
