Hanamaki Onsenkyo Hot Springs: Water & Baths
Yumoto is a convenient first stop for Hanamaki Onsenkyo’s hot springs, with several resort hotels close together. The other hot-spring villages lie farther apart, often a road journey from one another.
Spring character
Traditional inns, toji lodgings for longer bathing stays and modern resorts stand in the western Dai and Toyosawa river valleys. Hanamaki Onsenkyo has a long bathing history and several kinds of spring water. Simple springs are common here; other sources contain sulfur, sulfate or chloride.
At Namari, you stand in a natural-rock pool. Osawa’s outdoor pool sits beside the Toyosawa River. In Yumoto, modern hotels surround the resort gardens. In Dai, traditional inns line the village streets. The district is varied: the water, buildings and baths differ from one village to the next.
Villages, hotels and springs
The village names below identify hot-spring areas. Each area has individual hotels or bathhouses, and each property uses one or more springs. The hotels in one village can have different water. At Yumoto, Hotel Hanamaki, Koyokan and Senshukaku share a supply; Kashoen uses its own spring. Dai’s inns stand close together, and you can visit several of their free-flowing baths. Their springs differ from inn to inn. The water shared by Yumoto’s three large hotels is clear, tasteless and odorless.
