Katasekan Hiina

Katasekan Hiina occupies a hillside position above Sagami Bay in the Katase Onsen district of Higashiizu-cho, its nine baths fed by a 96°C chloride spring that deposits 湯の華 precipitate — a mineral honesty that distinguishes it from inns that merely heat their water. Chef Koji Koyanagi carries a lineage traceable to Kitaoji Rosanjin; his WAON programme channels Izu's coastline and interior mountains into a kaiseki sequence built around kinmedai, spiny lobster, and abalone — ingredients that could not arrive from anywhere else on the map.

The Ishii Architectural Office has given the rooms a contemporary Sukiya openness — extended verandas facing the Pacific, private Shigaraki ceramic rotenburo on raised terraces — that serves this particular site better than enclosed tradition might, though guests seeking the earned patina of wabi-sabi will register the absence of garden moss, aged timber, and seasonal alcove. The one thing a guest will remember: a private ceramic rotenburo at midnight, the Izu Islands barely visible on the dark horizon, Sagami Bay receiving the full weight of the stars.
