Kankoku Tenbosho (Korea Observatory) is a scenic observation facility located in Kamitsushima, the northern part of Tsushima Island, Nagasaki Prefecture. Situated approximately 49.5 km from Busan, South Korea, it offers a unique perspective of the neighboring country. When weather conditions are favorable, visitors can clearly see the cityscape and even the shimmering lights of Busan. The architecture itself is a highlight, deeply influenced by the geographical and historical ties between Japan and Korea. The observatory and gates incorporate traditional Korean architectural elements, allowing you to feel the presence of the neighboring nation while standing on Japanese soil.
This observatory was developed as a symbol of the historical connection between Tsushima and Korea. The design of the facility is intentionally infused with Korean cultural elements. Specifically, the observatory structure is modeled after multi-purpose facilities found in Seoul's Pagoda Park, while the entrance gate is inspired by the entrance to the Korea International Terminal in Busan. This choice of architectural style serves as a visual representation of the historical and cultural bonds between the two nations, making the site much more than just a simple viewpoint.

The primary attraction is the expansive view that allows you to gaze toward the city of Busan, South Korea. On certain nights, the view of Busan's beautiful night skyline is truly spectacular. Additionally, the structures themselves—the observatory and the gates designed in the Korean architectural style—are essential parts of the experience. The facility is well-equipped for travelers, offering free parking and accessible restrooms, ensuring a comfortable stay. It is a perfect place to experience the vastness of the sea and the sense of proximity to a neighboring country.
For the best experience, visiting in April, May, September, or October is highly recommended. During these months, the weather tends to be more stable, providing clearer visibility. Regarding the time of day, visiting at night is a great option if you wish to see the city lights of Busan. During the daytime, you can enjoy the striking contrast between the blue sea and the distant Korean cityscape, while nighttime visits offer a mesmerizing view of urban lights.
The main activity here is simply enjoying the view from the observatory. It is a popular stop for those on a scenic drive, where a stay of a few dozen minutes is enough to soak in the scenery. Taking photographs with the Korean-style architecture in the background is a unique way to spend your time. Observing the landscape helps travelers gain a deeper understanding of the unique geographical characteristics of Tsushima.
Nearby attractions include Minohama Beach and the Isekonomieru Oka Observatory. You can also explore sites that touch upon the history and culture of Tsushima, such as the Tenjin Takuheadama Shrine and the Asahidake Kofun (ancient burial mound). Combining these nearby spots with your visit to the observatory will provide a multi-faceted way to experience the nature, history, and international connections of Tsushima.
