Mimasaka Three Hot Springs
Yubara Onsen in Maniwa City, Okutsu Onsen in Kagamino Town (Tomata District), and Yunogo Onsen in Mimasaka City-all located in the northern part of Okayama Prefecture-are collectively known and cherished as the “Mimasaka Three Hot Springs,” representing some of the most famous hot spring resorts in Okayama.
The biggest draw at Yubara is definitely the open-air mixed-gender onsen 'Sunayu.' It's free, has mountain views, and is just super cool.
