About this onsen
Nishiura Onsen spreads over the tip of the Nishiura Peninsula jutting into Mikawa Bay in Gamagori, Aichi. Inns line the coast, and the area is famed for its sunsets over the bay. Suehiro stands on a hill of the peninsula, and its rooftop open-air bath offers some of the best views in Nishiura, taking in the peninsula and its islands. The 'Bihaku' spring piped to the 1st-floor grand bath is an alkaline simple spring low in salt and calcium — rare for a coastal area — and is loved as a gentle bath for the skin.
Good to know
Day bathing runs Friday to Monday, 11:30-15:30 (last entry 14:30), for 1,500 yen per adult (elementary 900 yen, toddlers 600 yen, bath towel rental 300 yen, tax included). The inn is closed Tuesday to Thursday. The rooftop open-air bath has no washing stations — rinse with ladle water before entering — and has no roof, so it may close in bad weather. Private open-air baths (2 people, 45 minutes, 2,500 yen) require reservation. A free shuttle runs from Meitetsu Nishiura Station.
