Korean Observatory

Located at the northernmost tip of Tsushima City, Nagasaki Prefecture, this observatory stands in the border town of Kamitsushima, just 49.5 km from South Korea. On clear days, visitors can see the cityscape and even the nighttime lights of South Korea with the naked eye. Looking out at a city across the sea offers a special experience that brings the proximity of the international border into sharp focus.

The observatory's architecture was inspired by a multipurpose facility in Seoul's Pagoda Park, while its gate was modeled after the entrance to the Busan International Passenger Terminal. The Korean-inspired design symbolizes the area's identity as a border town. From the observation deck, visitors can take in the changing scenery of the strait at different times of day and in different weather. Blue sea and sky stretch into the distance during the day, the setting sun colors the horizon in the evening, and at night, the lights of Busan and fishing boats create an atmospheric scene.

Parking and restrooms are available at and around the observatory. It is one of Tsushima's signature sightseeing spots, offering both scenery distinctive to a border island and a taste of another culture.
