Higashiizu Onsen Katase is a coastal hot spring facility in Higashiizu, a town on the eastern coast of the Izu Peninsula, Shizuoka Prefecture, Japan, an area known for its dramatically scenic Pacific coastline, abundant marine fishing, and the warm Kuroshio Current that moderates the climate year-round. The naturally chloride-sodium spring waters are prized for their deeply warming properties characteristic of Izu's coastal geothermal zone, offering bathers a soothing experience with the possibility of combining mineral soaking with views over the Pacific Ocean and the rugged Izu coastline. As part of the eastern Izu thermal circuit beloved by travelers from Tokyo, Higashiizu's onsen provide an intimate and genuinely restorative seaside hot spring experience in one of Japan's most scenic coastal destinations.
