A high-speed boat service linking South Korea's port city of Busan and Tsushima, the Japanese island that lies closest to the Korean Peninsula, resumed Saturday after a three-year halt due to the coronavirus.

The restart of the route between Busan and Hitakatsu port in Tsushima, Nagasaki Prefecture, comes amid growing hopes in both countries for increased travel to Japan's "border island."

Two South Korean operators serve the route, mostly on weekends for the time being, with the number of passengers limited to 100 per sailing. Seats on passenger ships departing Busan are fully booked until the end of next month.
