About this onsen
Yunohama Onsen is one of the historic seaside hot spring resorts of the Shōnai region in Yamagata, facing the Sea of Japan. Its spring is a sodium-calcium chloride (salt) spring, rich in salt and said to keep the body warm. The area is lined with beachside resort hotels and inns, the Kamo Aquarium is nearby, and sunsets over the Sea of Japan are beautiful.
Good to know
Day bathing is 12:00-16:00: 1,000 yen for adults (tax excluded, towel and bath towel included) and 500 yen for children (up to elementary school, tax excluded). Only the 2nd-floor large bath is available. Some days are unavailable due to closure days, so it is wise to confirm by phone before visiting.
