Arima Onsen, one of Japan's oldest hot spring resorts and counted among the three most famous onsen in Japan. During the Meiji era, when Kobe opened its port to foreign trade, many foreigners visited Arima Onsen. They also visited the renowned autumn foliage spot "Kiyomizu-dera," which later became a foreigner-exclusive hotel called "Kiyomizu Hotel." The lush green grounds of "Arima Sanso Goshobessho" still retain the sacred atmosphere of that time. Goshobessho was established by Shirobei Kanai XV, the current head of "Tosen Goshobo," Arima Onsen's oldest accommodation. All 10 suite rooms at Goshobessho are detached and feature private onsen baths and low-temperature saunas known as "Thermal Rooms." One of these suites even includes the world's first treehouse-style open-air bath.
