Taisenkaku

Taisenkaku is a 68-room Harazuru Onsen property whose personality is concentrated in its bathing spaces. The building is large and practical, serving families and groups more readily than travelers seeking a secluded old inn.

Seasonal kaiseki is a genuine strength, using regional ingredients in generous courses and giving dinner more polish than the resort scale might imply.

Two distinct waters—alkaline simple and sulfur springs—supply six bathing areas. The tropical-planted jungle bath, complete with a slide, is the memorable centerpiece; open-air, private, and sauna options broaden the circuit, and the private outdoor baths use free-flowing water. Taisenkaku suits guests who enjoy variety and character in an onsen, with a substantial meal alongside it.
