Miya Onsen Hotel Meizansō
三谷温泉 ホテル明山荘（日帰り入浴）
A large hotel on a rise above Mikawa Bay in Gamagōri, part of Miya Onsen, whose waters are said to have been discovered 1,200 years ago by the monk Kūkai. Unusually for a coastal spa, the low-salt alkaline simple spring is known as 'beautiful-skin water'. Highlights are the open-air hot spring bath Bihakusen and 13 kinds of spa facilities across the men's and women's sides – lie-down baths, waterfall showers, saunas – with views over the bay toward Takeshima island. Day bathing runs 11:30–19:00 for ¥1,600 per adult (face towel ¥200 and bath towel ¥300 extra). Prices have risen, but the spacious halls and views are often yours alone in quiet hours; day plans with meals and private rest rooms are offered. Open every day, with free parking for 200 cars. About 5 minutes by car (20 on foot) from Mikawa-Miya Station on the JR Tōkaidō Line, or 20 minutes from the Otowa-Gamagōri IC on the Tōmei Expressway. Combine with Laguna Ten Bosch, Takeshima or mandarin picking on a Mikawa Bay drive.
