Beppu to Jeju City Road Trip Guide: Routes, Stops & More

This route is not a simple road trip: it's a multimodal journey that begins on Japan's Kyushu island, traverses the Kanmon Straits, and ends on South Korea's Jeju Island. The most direct driving path covers roughly 1,100 kilometers from Beppu to the port of Busan, followed by a 12-hour ferry crossing to Jeju City. A unique quirk: the Japanese section includes toll expressways where you pay per distance, while in South Korea all tolls are prepaid via the Hi-Pass system.

Driving from Beppu to Jeju City isn't a continuous highway hop; you'll need to plan around ferry schedules and international borders.

Begin on the E34 Higashikyushu Expressway heading north from Beppu to Kitakyushu. Continue via the Kyushu Expressway to Fukuoka's Hakata Port. Drive your vehicle onto a car ferry to Busan (book at least a week ahead). After disembarking, connect to the Namhae Expressway to reach Busan Port, where a separate ferry takes you to Jeju City.

• The Japanese expressway toll from Beppu to Fukuoka is about ¥5,500 (approximately $50).
• Car ferry from Fukuoka to Busan: from ¥25,000 (about $170), 3.5 hours.
• Car ferry from Busan to Jeju: from ₩120,000 (about $90), 12 hours overnight.

Fuel costs vary significantly: in Japan, gasoline averages ¥170 per liter (about $1.55), while South Korea is slightly cheaper at ₩1,800 per liter (about $1.30). The total driving distance within Japan is about 240 kilometers, and within South Korea (from Busan to the port) roughly 30 kilometers. Overall, the journey takes about 19 hours including ferry wait times. Is it worth driving Beppu to Jeju City? If you want the flexibility to explore both countries at your own pace, yes.

Kyushu's volcanic terrain defines the first leg. Beppu's hot springs steam beside fields of citrus and bamboo. The drive north passes the Kuju Mountains, part of Aso-Kuju National Park, and skirts the crater of Mount Aso, one of the world's largest active calderas. Across the strait, Busan's coastal roads reveal cliffs and the famed Haeundae Beach.

Jeju Island itself is a UNESCO World Heritage Site for its lava tubes and volcanic cones, like Hallasan, the highest peak in South Korea. The island's coastline shifts from black basalt cliffs to white sandy beaches, a contrast shaped by millions of years of eruptions.

Local commerce thrives along the way. In Beppu, jigoku-mushi (steam-cooked) dishes are a must-try. Fukuoka's yatai (street food stalls) serve tonkotsu ramen. On Jeju, black pork barbecue and hallabong (a type of citrus) are staples. For handmade crafts, stop at Jimbeop Port Market in Busan, where you'll find folk paintings and woodwork.

Throughout the journey, you'll notice regional products: Ureshino green tea on Kyushu, and Jeju's famous green tea plantations. These make excellent road trip souvenirs.

Road quality is excellent on both expressways and national roads. In Japan, the E34 has frequent rest areas with clean toilets and vending machines. In South Korea, the Namhae Expressway offers similar amenities, with service areas displaying route numbers and distances. Speed limits are strictly enforced: 100 km/h on expressways in both countries, except in sections where lower limits apply.

For families, stop at the Kuju Flower Park in Oita Prefecture, a kid-friendly garden with seasonal blooms. At Fukuoka's Marinoa City, you'll find an observation wheel overlooking Hakata Bay. On Jeju, the Jeju Glass Castle is a hit with children.

Pet-friendly infrastructure is well-developed. Japanese rest stops have leash-free zones, and many ferries allow pets in kennels. In South Korea, pet-friendly accommodations are common. When booking ferries, always inform them of your pet's size and breed.

Fatigue management is critical. The drive within Japan takes about 3.5 hours; break it at Yamaguchi City, roughly halfway. During each ferry ride, you can rest in reclining lounges or cabins. On the open road, take a 15-minute break every 2 hours—try rest areas like the Mizuki IC Service Area, which has excellent views of the Ariake Sea.

Hidden off-route spots abound. In Kyushu, detour to the Kumamoto's Sakuranobaba Johsaien, a cultural complex near Kumamoto Castle. In Korea, take a small coastal road to Dadaepo Beach, sunset favorite. For a more challenging drive, explore the 1131 road on Jeju, which winds through the island's volcanic hills.
