About
Sanyoso stands at the foot of Mount Genji in Izu-Nagaoka Onsen and is run by Seibu Prince Hotels. The main building was built in 1929 as the villa of Hisaya Iwasaki, eldest son of the Mitsubishi founder, and was registered as a tangible cultural property in June 2017. The new wing, completed in 1988 to a design by Togo Murano, is sukiya-style architecture inspired by the Katsura Imperial Villa. The garden, laid out by the Kyoto gardener Ogawa Jihei, covers about 3,000 tsubo, roughly 10,000 square metres. There are 36 rooms. Main-building rooms take their names from Noh plays and new-wing rooms from The Tale of Genji. Every room has natural hot spring water, and there are large public baths and open-air baths looking onto the garden. Dinner is multi-course kaiseki. Izu-Nagaoka Onsen is on the Izu-Hakone Railway from Mishima, one Shinkansen stop west of Atami.
