Beautiful property. If you’re looking for a traditional Japanese experience, this is the place. FYI, if you have tattoos, you will not be able to use the public Onsen, but book a room with a private Onsen and you’re all set.

The onsen Ryoken is a famous one in Japan as the Japanese Emperors had stayed at the estate for a few times. We stayed at a room with private onsen which is excellent. The food was also great and we had a great time.
