Old traditional family run inn with simple rooms but really delightful atmosphere. The building is a bit of a patchwork of different eras, but that only adds to the vibe. The food was also delicious even though we only had a breakfast. There’s also a room with an old Iori fireplace which can be booked for meals for truly old style experience. The bath was also nice.

Very old, traditional, family-operated Onsen hotel. We have had an excellent experience. Their food is amazing. Given we arrived on our bikes after a long, rainy day - they even washed and dried our clothes.

fantastic service and onsens, food amazing

Great place to stay servings traditional dinner and breakfast. Away from the bustling city

Koyabu Onsen's slippery water quality was excellent for moisturizing the skin. I loved the rock bathtub and the old building, both of which had a very calm and elegant atmosphere. I want to go again.
