Nishiizu Onsen Matsuzaki is located in Matsuzaki, on the western coast of the Izu Peninsula in Shizuoka Prefecture, facing the Suruga Bay — one of Japan's most scenically dramatic Pacific coastlines, where volcanic sea cliffs, hidden coves, and the exceptional clarity of the warm Suruga current create a landscape that local people call 'the best sunset in Japan' as the sun drops into the sea behind the Mount Fuji silhouette. The chloride-rich coastal hot spring waters of western Izu's geothermal zone provide warm saline mineral bathing in a setting where the Pacific sunset, the fishing boat culture, and the historic namako (sea-cucumber texture plaster) warehouses of Matsuzaki's beautifully preserved old district create a uniquely atmospheric coastal Japan experience. Matsuzaki is the setting of a famous tale by Nobel Prize laureate Kawabata Yasunari — 'The Dancing Girl of Izu' was written in the town and inspired by his travels through the western Izu peninsula — giving the coastal onsen town a literary resonance that deepens its appeal for culturally sensitive visitors.

Insider tip — Nishiizu Onsen at Matsuzaki faces the open East China Sea on the wild western flank of the Izu Peninsula, where sodium-chloride waters flow into clifftop outdoor baths with unobstructed ocean sunsets. The 40°C seawater-like mineral baths pair perfectly with the town's famous namako-kabe black-and-white plaster walls, a unique architectural heritage dating to the Edo period. The combination of thermal bathing and coastal scenery makes Nishiizu one of the most visually dramatic onsen destinations in Honshu.
