Ichinomata Onsen Grand Hotel
An inn at Ichinomata Onsen in the hills of Toyota, Shimonoseki, famed for 'toro-toro' water — a strongly alkaline simple sulphur spring at pH 10.0, among the highest in Japan. The skin turns slippery the moment you get in and silky afterwards, and it is widely known in Yamaguchi as a beauty bath. The Honoka and Yunoka halls have indoor and open-air baths and saunas, plus reservable private baths — a round cypress tub and a square stone one — at ¥2,000 per hour. Day bathing: adults ¥1,150, children ¥600, 08:00–21:00 (last entry 20:00); note the shortened 08:00–17:00 (last entry 16:00) on Saturdays, holidays, Golden Week, Obon and New Year. A rest lounge and restaurant (11:30–15:00) allow a bath-and-lunch visit. About 30 minutes by car from Ozuki or Mine IC on the Chūgoku Expressway, or 40 minutes by bus from JR Ozuki Station. Combine with Tsunoshima Bridge, Akiyoshidai or Nagato-Yumoto. The nearby Ichinomata Onsen Kankō Hotel is a sister property.
