Tsushima Strait

The Tsushima Strait is a maritime passage separating Japan and South Korea, stretching roughly 100 kilometers with a width of about 65 kilometers at its narrowest point. The waters reach depths up to 140 meters, creating a natural channel between the two countries.

The strait saw a major naval battle in 1905 when Russian and Japanese fleets clashed, with Japan emerging victorious. This confrontation shifted the balance of power in East Asia.

The waters here have long served as a bridge between two nations, with people crossing to share goods, ideas, and beliefs. Today, ferries still carry travelers back and forth, keeping this connection alive.

Regular ferry services connect ports on both sides, making crossing accessible for travelers. Plan your journey during calmer weather periods, as conditions can vary depending on the season.

The strait has an unusual territorial arrangement where waters extend only three nautical miles instead of the standard twelve. This setup allows freer passage for ships traveling between the two nations.
