別邸四季(べっていしき)

A private bath means soaking whenever, and for as long as, you like. From the moment you take the key, this house is yours.

Swim in your private pool, take a slow sauna, or fire up a terrace BBQ — how the hours pass is entirely up to you. Your dog is welcome, too.

You will be planning next season's visit before you leave. Check the official site for current rates and availability.
