Nagasaki to Busan Road Trip Guide: How to Drive

Driving from Nagasaki to Busan involves a unique international journey: you'll traverse the Japanese island of Kyushu to the port of Hakata in Fukuoka, then take a ferry across the Tsushima Strait. The total driving distance from Nagasaki to Hakata is about 170 kilometers, taking roughly 2.5 hours via the Nagasaki Expressway and Kyushu Expressway. In Busan, you can pick up a rental car and continue on South Korea's excellent highway network.

The route from Nagasaki to Fukuoka unfolds through green hills, terraced rice paddies, and coastal glimpses. After leaving Nagasaki, you'll pass near Mount Unzen, an active volcanic peak, and soon reach the Ariake Sea, known for its tidal flats—best seen at low tide. As you approach Fukuoka, the landscape becomes suburban, but just south of the city is Dazaifu, home to the ancient Shinto shrine Dazaifu Tenmangu, dedicated to the scholar Sugawara no Michizane.

In Busan, the natural highlight is the Taejongdae Resort Park, with dramatic cliffs and dense forest. For local commerce, Nagasaki's Chinatown and Busan's Jagalchi Fish Market offer contrasting culinary experiences. Along the Japanese expressway, rest areas (SA) feature local specialties: try Nagasaki's champon and Fukuoka's tonkotsu ramen. In Busan, don't miss the famous street food at BIFF Square.

Both Japan and South Korea have well-maintained highways and moderate congestion outside cities. Japan has strict speed limits (100 km/h on expressways) and frequent radar; observe them. In Korea, limits are similar, but enforcement is more lenient. For pets, both countries require a microchip, valid rabies vaccination, and an import permit. Many expressway rest stops on the German autobahn have pet relief areas, but in Japan they are less common—plan stops accordingly.

For families, roadside stations (Michi-no-Eki) in Japan offer playgrounds and open spaces. In Korea, rest areas (휴게소) have family-friendly amenities. To combat fatigue, break every 2 hours. On the Japanese leg, well-marked rest stops are every 30 km. On the Korean side, similar spacing applies. If you want to explore off-route spots, consider the hidden hot spring town of Takeo Onsen south of Saga City, just a short detour from the expressway.

Take the Nagasaki Expressway (E34) east to the Kyushu Expressway (E3) north, reaching Fukuoka's Hakata Port. Tolls for a standard car total around ¥3,500. Fuel costs in Japan average ¥1,300 per liter for regular gasoline; for a car averaging 12 km/L, you'll need about 14 liters, costing roughly ¥18,200. In South Korea, gasoline is cheaper, averaging ₩1,500 per liter (approx. ¥1,100).

The JR Beetle ferry operates daily between Hakata and Busan, with a crossing time of about 3 hours and 5 minutes. Fares start at ¥9,000 for standard one-way. Reserve in advance, especially during peak seasons. On the Korean side, Highway 1 connects Busan to the rest of the country—a major toll expressway with good signage.

• Driving time on expressways: 2.5 hours (Nagasaki to Hakata) + 0.5 hours (Busan to city center) = 3 hours total driving.
• Ferry check-in: arrive at least 1 hour before departure.
• International driving permit (IDP) required for both Japan and Korea.
