Katahara Onsen

Katahara Onsen wells up on the western slope of Mount Sangane in Gamagori City, Aichi. Inns are scattered along the hillside roads, letting you enjoy mountain greenery and views of Mikawa Bay at once. Its smooth alkaline simple water has long been loved as a spring good for the skin.

Highlights

- A hydrangea garden where some fifty thousand plants are said to bloom in early summer - Smooth, gentle alkaline simple spring water - Hillside scenery taking in both mountains and sea - The lively hydrangea festival held each June

Enjoying the Seasons

The standout time is early summer, when June hydrangeas wash the slope in blue and purple and draw many visitors. Summer offers cool shade and autumn brings clear views, while winter is ideal for soaking slowly in the smooth water amid mountain quiet.
