  • I stayed here during a three-day weekend to visit the Kumano Kodo. The free Shuttle Service to the trail was very convenient. The Room was a spacious and clean Japanese-Western style room. I made the Reservation without realizing it was No Meals Included, so I had dinner at the dining area by the large public bath, which was beautifully lit up. For breakfast the next morning, I was able to reserve rice balls.The shop had a wide variety of souvenirs, but when I tried to buy some at the station on my way home, there was nothing available. I should have bought them at the Accommodation.

Notice from the Accommodation

[Notice of Outdoor Onsen Facility Hot Water Supply Construction]
Thank you for always choosing Watarase Onsen.

Starting from July 1, 2024, we will be conducting excavation work within the outdoor Onsen Facility to secure a stable hot water supply. During this period, the men's outdoor Onsen and three areas at the back will be unavailable. Depending on the progress of the construction, there may also be restrictions on access to other areas. The construction is expected to take approximately one and a half years to complete.

We sincerely apologize for the inconvenience caused over this extended period and kindly ask for your understanding and cooperation.
