Tsushima Island

Yes — Tsushima Island is real. It's a remote Nagasaki archipelago in the strait between Kyushu and the Korean Peninsula, closer to Busan than to Fukuoka, and reachable on a two-hour Jetfoil from Hakata Port. Two main islands, roughly 700 square kilometres of mountain and coastline, around 30,000 residents, and almost no foreign tourists outside the gaming-curious. This guide covers the ferry and flight routes, what's actually on the island once you arrive, and why the historical layer is the part most write-ups skip.

What to Expect

The Strait Where Two Countries Meet

From the northern town of Kamiagata, on a clear day, you can see the lights of Busan. The Tsushima Strait is 50 kilometres wide at its narrowest point — closer than London to Calais — and the island has spent 1,500 years as the place where Japan and the Korean Peninsula brushed against each other. Diplomatic missions, trade convoys, two failed Mongol invasions, and a slow modern reorientation toward South Korean ferry tourism. The borderland framing isn't a marketing line; it's the actual identity.

Watatsumi Shrine and the Sea-Torii

On the western coast, Watatsumi Shrine has five vermilion torii gates marching from the shrine grounds out into the sea. At high tide three are partially submerged; at low tide you can walk to the furthest gate on stone steps. The shrine is dedicated to Toyotama-hime, a sea-deity from the founding myths of imperial Japan. It's a 50-minute drive from Izuhara on the southern island. Without a rental car, you're looking at infrequent local buses — plan ahead.

Mongol-Invasion Beaches and Stone Forts

In 1274 a Mongol fleet of 900 ships landed at Komodahama Beach on Tsushima's southwestern coast. The local garrison of 80 samurai was wiped out in a day. The actual beach is unmarked except for a small memorial stone, and that absence of curation is precisely the point — you walk a wide, quiet bay and the history is in the geography itself, not in plaques. Kaneda Castle, the 7th-century stone-walled fortress on Mount Joyama, was rebuilt by the Yamato court specifically because of Tsushima's exposure to mainland forces. Both sites take about half a day combined.

How to Get There

The JR Pass does not cover the Jetfoil or the ANA flight. Book at least two weeks ahead during summer and Japanese holiday weeks. For more on island-hopping Kyushu, see our Kyushu region guide.

Tips

• Rent a car. The bus network is thin and the main sights are spread across two islands connected by a single bridge. A small rental from Toyota Rent-a-Car at Izuhara Port runs around ¥6,000–¥8,000 per day — verify current pricing. International driving permit required.
• Book the ferry both ways before you fly to Fukuoka. Summer Jetfoils sell out and the slower car ferry (5 hours) is a long backup. Jetfoil tickets via Kkday avoid the Japanese-language booking flow.
• Typhoon season is real. July through September the Jetfoil cancels regularly — sometimes for two or three days in a row. If you must travel then, build in a buffer day on either side.
• Mobile reception thins out north of Mitsushima. Download offline maps before you leave Izuhara. Convenience stores are sparse outside the main town — bring snacks and cash for the all-day driving loop.
• Stay two nights minimum. One night gives you Watatsumi and Izuhara; two nights gets you the northern Kamiagata view and the Komodahama beach. Tsushima Grand Hotel in Izuhara is the easiest mid-range base.
