About this site
Hisui Beach (ヒスイビーチ) is a shore-entry site at Asahi on Toyama Bay, Toyama, with a maximum depth of 12 m and an average around 8 m. The coast here runs for some 4 km and is known for the jade (hisui) pebbles found along it, and jade also lies underwater, so divers search the bottom for it. Gentle current; suitable from beginner level. The shallows inside the offshore breakwater are used for certification courses and refresher dives, with lumpfish and nudibranchs among the life.
