Tsushima Island: A Border Island Where Continental and Japanese Cultures Intersect

Tsushima in Tsushima City, Nagasaki, is an island floating northwest of Kyushu, a border island about 50 km to Busan, South Korea, and about 132 km from the Kyushu mainland. Functioning since ancient times as a relay point linking the Korean Peninsula and Japan, it is a historic island recorded even in the Nihon Shoki. Rich nature and a distinctive culture are alive here, and in recent years it has grown popular with travelers seeking history and grand nature.

Highlights

The Joseon Envoys and the So Clan

The Joseon Tsushinshi, the diplomatic envoys dispatched from Korea to Japan during the Edo period (1607 to 1811), always passed through Tsushima. The So clan, who ruled Tsushima, handled the diplomacy and hospitality for the envoys, playing an important role as the window of Japan-Korea diplomacy. Many materials and historic sites conveying the history of that time remain in Tsushima. The ruins of Kaneishi Castle, the residence of the So clan, and Banshoin, their family temple, are also highlights.

The Tsushima Leopard Cat

The Tsushima leopard cat, which inhabits only Tsushima, is a rare wild cat designated a national natural monument. An endemic subspecies retaining traces of the era when it was connected to the continent, its population is said to be very small, and it is a precious species whose extinction is feared. At the Tsushima Wildlife Conservation Center, you can learn about conservation activities and its ecology (admission free).

Coastal Spectacles and Historic Spots

The seas around Tsushima are beautiful, and you can enjoy snorkeling and swimming in the highly transparent water. Miuda Beach, selected among Japan Top 100 Beaches, is a famous beach with a spread of white sand. The Eboshidake Observatory, which overlooks the intricate ria coastline, is also spectacular. In addition, historic sites connected to the naval Battle of Tsushima in the Russo-Japanese War, and the Manzeki Bridge spanning the ria coast, are highlights unique to Tsushima.

Seasonal Enjoyment

The best season for Tsushima is from spring through autumn, when the sea is calm and the climate fine. In summer, you can enjoy snorkeling and swimming in the highly transparent sea, and beaches such as Miuda bustle. In autumn, the air is crisp and the view of the ria coast from Eboshidake Observatory becomes even more vivid. In winter, migratory birds arrive from the continent, and birdwatchers visit too. Throughout the seasons, you can feel the distinctive nature close to the continent, unique to a border island.

Access and Essential Information

To reach Tsushima, flying from Nagasaki Airport or Fukuoka Airport is convenient, about 35 minutes from Fukuoka Airport, with direct flights from Nagasaki Airport as well. By sea, high-speed boats and ferries run from Hakata Port, with the ferry taking about 4 and a half hours and the high-speed boat linking in a shorter time. Since the island is long and broad from north to south, a rental car is basic for getting around. Public transport is limited in frequency, so reserving a rental car in advance is reassuring. Tsushima leopard cats and wild boars sometimes cross the roads, so take ample care for safety when driving.

Practical Travel Notes

• Best time: The Eboshidake Observatory is especially beautiful at sunset, and sea activities such as Miuda Beach are best in the morning when the sunlight is mild.
• Touring tip: Since the island is broad and highlights are scattered from north to south, a rental car is essentially a must. Planning two days with one night or more lets you tour with room to spare.
• Time needed: About 2 days to tour the main spots. To be greedy with history, nature, and the sea, two nights or more is ideal.
• Real nearby spots: Miuda Beach, Eboshidake Observatory, the Tsushima Wildlife Conservation Center, Banshoin, and the Manzeki Bridge are scattered across the island.
• Budget feel: Transport (air tickets and ferry) and rental car costs are the main expenses. The observatory and beaches are free, and admission to the conservation center is also free.

A Word of Advice

Tsushima is a special destination where you can savor at once the history where Japan and the continent met, unique to a border island, and untouched grand nature. Since travel distances are long, planning a relaxed two days with one night or more rather than a day trip is recommended. While driving, watch for Tsushima leopard cats darting out, and enjoy your trip with a mind to protect the rare creatures and nature. It is a deep island that satisfies both history lovers and nature lovers.
