While the booking said they spoke English no one, but one lady saying hello spoke English. To be fair I was with a Japanese friend,but no attempt to interact with me. And, to be labeled 'we speak your language' none of the print material including resort menus were in English. The staff were not very forthcoming with local eateries either. None of these howeve would keep me from going back.
The hotel sits on an exclusive beach, there are no other hotels on the beach. The town it sits in is small and quiet. On our way to the hotel the shuttle bus driver told us the busy times of the hot springs to avoid. However, we never experienced more than row or three others at the most each time we went, busy or not. It's a perfect get away to experience a beautiful beach and a little of local small town Japan.
