How to read this map
The Sea of Japan covers about 978,000 km² (378,000 sq mi) and reaches a maximum depth of about 3,742 m (12,277 ft). Countries with a coast on the Sea of Japan: Russia, Japan, North Korea and South Korea.
The blue outline marks the Sea of Japan as mapped by Natural Earth. Towns and cities on the map include Tokyo, Osaka, Seoul, Shenyang, Yokohama, Harbin, Busan and Pyongyang. Labeled countries: Japan, North Korea and South Korea.
Greens show lower elevations; tan and brown show higher land, with pale tones toward the highest terrain. Shadows emphasize the slopes, and vertical relief is exaggerated so landforms are easier to read. Dashed lines show country borders.
The relief uses Terrain Tiles (SRTM, GMTED2010 and ETOPO1 elevation data). Rivers, lakes, borders and the outline of the Sea of Japan come from Natural Earth, and the figures on this page from Wikidata. Natural Earth draws features at a small scale, so the outline is a guide to where the Sea of Japan is, not a surveyed boundary.
