The oldest hot spring resort in Yamaguchi Prefecture, with a history of about 600 years. In recent years, it has undergone a dramatic transformation through "onsen town renovation," and has been reborn as an "outdoor paradise that makes leisurely strolls a pleasure," featuring riverside terrace seating along the Otozure River, enchanting night illuminations, and the day-use bathhouse "Otozure." World-class luxury resort brands have also moved in, and its beautiful landscape, where the atmosphere of a traditional Japanese hot spring town blends with a refined modern resort space, has become an exceptionally compelling destination for travelers from overseas seeking a high-quality stay.
