Is Tsushima a Real Place? The Actual Island Behind Ghost of Tsushima

Is Tsushima a Real Place? Yes — And You Can Visit

Tsushima (対馬) is a real island in Nagasaki Prefecture, Japan. It sits in the Korea Strait between Japan and South Korea — closer to Busan (49.5 km) than to mainland Japan. The island became internationally famous after the 2020 PlayStation game Ghost of Tsushima, which depicted the Mongol invasion of 1274, but Tsushima has been inhabited for thousands of years and remains home to about 28,000 people.

Unlike the game's dramatic open grasslands, the real Tsushima is 89% mountain forest with small fishing villages clinging to a deeply indented coastline. It is remote, quiet, and distinctly unlike any other destination in Japan. If you are planning a trip to the Nagasaki region, Tsushima offers something entirely different from other Nagasaki islands — a place where Japanese, Korean, and Mongol history collide on a rugged, forested frontier.

The Real Mongol Invasion: History Behind Ghost of Tsushima

The first Mongol invasion of Japan in 1274 — the historical event at the heart of Ghost of Tsushima — is real. Kublai Khan's fleet, numbering roughly 900 ships and 30,000 soldiers, struck Tsushima as its first target before moving on to Iki Island and Hakata Bay (modern-day Fukuoka). The island's small garrison, led by the historical figure Sō Sukekuni, was overwhelmed.

The game takes creative liberties with the story, but the core premise is grounded in documented history. According to the Tsushima City government, Mongol invasion-related sites including Kaneda Castle ruins and stone monument towers (十二面石塔) hold national historic site designation. A second Mongol invasion followed in 1281, and Tsushima again bore the first blow.

What the game does not show is Tsushima's longer history as a diplomatic bridge between Japan and the Asian continent. Kaneda Castle (金田城跡) was originally built in 663 AD — six centuries before the Mongols — to defend against Chinese and Korean invasion after Japan's defeat at the Battle of Baekgang. After the Imjin War (文禄・慶長の役, 1592–1598), Tsushima's ruling Sō clan mediated peace negotiations with Korea and maintained trade relations for centuries.

What Tsushima Island Looks Like Today

Forested Mountains and Fishing Villages

The real Tsushima looks nothing like the golden fields and meadows of Ghost of Tsushima. The island stretches about 82 km north to south and is almost entirely covered in dense forest — cedar, cypress, and broadleaf trees blanket steep mountains that drop sharply to the sea. Tiny fishing villages sit in narrow coves along one of Japan's most convoluted coastlines.

The island is actually two main landmasses — Kamijima (upper island) and Shimojima (lower island) — connected by bridges across a narrow canal. Most visitors arrive at Izuhara Port on the southern tip or Tsushima Yamaneko Airport in the center. Unlike nearby Hashima Island, which is an abandoned industrial relic, Tsushima is a living, working island with supermarkets, schools, and gas stations — just on a very quiet scale.

Korean Cultural Influence

Tsushima's proximity to Korea — you can see the Korean coastline on clear days from northern lookout points — has shaped the island's culture for over 1,500 years. Korean influence is visible in the local cuisine, where beef barbecue and pickled vegetables share menus with Japanese sashimi and ramen. According to community reports on TripAdvisor, some locals speak Korean fluently, and Korean tourists arriving from Busan by high-speed ferry have historically outnumbered Japanese visitors.

Shinto shrines on the island reflect a blending of continental and Japanese spiritual traditions. Watatsumi Shrine, one of the island's most photographed sites, is dedicated to a sea deity and incorporates design elements that trace back to continental Asia.

Key Attractions and Historical Sites

Kaneda Castle Ruins (金田城跡)

Kaneda Castle is the marquee historical attraction on Tsushima and the site most closely connected to both the Mongol invasion history and Ghost of Tsushima's themes. Built in 663 AD atop a mountain overlooking Asō Bay, the fortress used natural stone walls and cliff faces to create a formidable defensive position. The hike to the ruins takes roughly 60–90 minutes from the trailhead and rewards visitors with panoramic views of the bay below.

Admission is free. The ruins are always open, though the mountain trail is best attempted in dry conditions. According to the Tsushima Tourism Association, the site is a designated national historic landmark.

Watatsumi Shrine (渡神社)

This ancient sea shrine sits prominently on the island and is dedicated to ocean deities. Visiting is free, with the grounds open from around 6:00 AM until dusk. The shrine's torii gate and forested approach are among the most photographed spots on the island and evoke the atmospheric shrine settings from the game — though the real version is more modest in scale.

Tsushima Leopard Cat Natural Park (ツシマヤマネコ自然公園)

The Tsushima leopard cat (ツシマヤマネコ) is an endangered wildcat found only on this island — and the inspiration for the animal companions in the game. Wild sightings are extremely rare, but you can see the cats at the Tsushima Leopard Cat Natural Park.

Asō Bay Coastal Scenery (浅茅湾)

Asō Bay is a rias coastline bay that divides Tsushima's two main islands. The deeply indented shoreline with forested islets creates scenery unlike anywhere else in Japan. Boat cruises are available seasonally, or you can view the bay from elevated lookout points along the road. This is the closest the real island comes to matching the game's sweeping landscape shots.

Getting to Tsushima: Flights, Ferries, and Travel Time

By Air from Fukuoka or Nagasaki

The fastest option. Flights from Fukuoka Airport to Tsushima Yamaneko Airport take approximately 30 minutes. Flights from Nagasaki Airport take about 35 minutes. Expect one-way fares in the range of ¥10,000–15,000 (~$67–100). Flight frequency is limited — typically 2–3 departures per day — so book ahead.

By Ferry from Hakata Port

Kyushu Yusen (九州郵船) operates ferries from Hakata Port (Fukuoka) to Izuhara Port on Tsushima's southern tip. The high-speed jetfoil takes about 2 hours 15 minutes. The standard ferry takes approximately 4 hours 30 minutes and is significantly cheaper.

There is also a high-speed boat service from Busan, South Korea to Hitakatsu Port on the island's northern end, taking 1 hour 15 minutes to 2 hours 15 minutes. Ferry schedules shown are from 2025 data — confirm current timetables before booking.

Practical Tips for Visiting Tsushima

• Rent a car at the airport — public buses exist but are infrequent and won't cover most scenic spots or historical sites. This is the single most important logistics decision for your trip.
• Bring cash — few ATMs operate outside the main port towns (Izuhara and Hitakatsu), and card acceptance is limited at restaurants and smaller shops.
• Plan at least 2 nights — the island covers about 700 km² with attractions spread between north and south. A day trip from Fukuoka is not practical.
• Best seasons: spring (April–May) for Tsushima cherry blossoms and autumn (October–November) for foliage. Summer offers swimming. Winter brings rough seas and frequent ferry cancellations.
• English signage is limited outside major tourist sites. Download offline maps and translation tools before arriving.
• Accommodation: ryokan and minshuku near the ports are the main options. Budget approximately ¥10,000–20,000 (~$67–133) per night.

If you're exploring other Nagasaki islands, consider pairing Tsushima with an Iki Island getaway — Iki is closer to the mainland and offers a more beach-oriented experience.
