If you’re keen to try the mixed bathing experience in Japan this is the place to try it!! Sukayu Onsen is one of Japan’s most authentic hot spring resorts, offering both separate and mixed bathing and both short and long-term stays. For those too shy to take the plunge, the resort offers women-only bathing hours for staying guests, or special towels for modesty!
Nearby Mt. Hakkoda and Oirase Mountain Stream offer some great options of hiking and nature walks before relaxing your tired muscles in the milky hot springs!
