Furuya Ryokan in Hakone Miyanoshita draws strongly sulfurous mineral water in Japan's most accessible mountain onsen resort — Hakone, 90 minutes from Tokyo by the Odakyu Romance Car through the Kanagawa highlands, where Mount Fuji reflects in Lake Ashi and 17 different volcanic spring sources produce waters of varying compositions across the caldera basin. Miyanoshita's historical distinction as Hakone's oldest and most refined onsen district — where the Fujiya Hotel hosted American presidents, John Lennon, Charlie Chaplin, and Winston Churchill since 1878 — gives Furuya Ryokan a cultural address of exceptional historical weight in the development of Japanese modern resort culture. The Hakone Open Air Museum, Hakone Checkpoint remnants of the Tokaido highway, the Old Tokaido road through cedar groves above Hakone, and the dramatic Owakudani volcanic valley with its sulphur deposits and black egg (kuro-tamago) cooking tradition surround this traditional ryokan with Hakone's layered combination of volcanic drama and historical significance.
