Bathymetric map of the Sea of Japan / East Sea, between Japan, the Korean Peninsula, Russia, and China. Shaded water depths show major features including the Japan Basin, Yamato Basin, Tsushima Basin, Yamato Ridge, and Toyama Trough, with surrounding straits and coastal cities.

Tall, rugged basaltic cliffs of Tojinbo rise above the shoreline along the Sea of Japan in Fukui prefecture, with waves crashing at their base and a calm sea beyond.
