Hiroshima to Suwon Road Trip Guide: Scenic Drive & Hidden Gems

The drive from Hiroshima to Suwon spans 850 kilometers, including a 220-kilometer ferry crossing from Fukuoka to Busan. This route crosses the Seto Inland Sea's islands, the Korean Strait, and the Korean Peninsula's western plains. The first documented crossing of this exact path by automobile was in 1965, part of a Japan-Korea friendship rally.

You'll travel via the Sanyo Expressway, the Kanmon Bridge, and Kyushu Expressway to Fukuoka, then ferry to Busan, and finally the Namhae Expressway to Suwon. Total driving time on roads is about 12 hours, plus a 3-hour ferry ride. This guide details the best stops, logistics, and practical considerations.

The route's natural highlights include the Seto Inland Sea's thousands of islands, visible from rest stops on the Sanyo Expressway; the volcanic terrain of Kyushu's Aso region; and the tidal flats of Suncheon Bay in South Korea. The climate shifts from Japan's humid subtropical (summer highs 35°C) to Korea's continental (winters -10°C).

Local commerce thrives along the way: in Japan, roadside stations (michi-no-eki) sell fresh seafood and citrus; in Korea, rest areas offer bulgogi burgers and ginseng tea. For unique souvenirs, stop at the Shimonoseki Karato Market for fugu, or the Gwangjang Market in Seoul (detour) for bindaetteok. This how to find the best stops and hidden gems between cities guide offers strategies for discovering local favorites.

Fuel costs vary significantly: Japan averages $1.50 per liter, South Korea $1.40. A typical sedan consumes $120 in fuel one-way. Tolls on Japanese expressways amount to $150, while Korean highways cost $40. The ferry (Beetle or Kobee) costs $150 for a car and driver.

Border crossing at Busan port takes 1-2 hours; have your car's export documents ready. Ensure your insurance covers both countries; some policies exclude ferry transit.

• Use the Sanyo Expressway (E2) from Hiroshima to Shimonoseki.
• Cross Kanmon Bridge (toll ¥400) to Kyushu.
• Take Kyushu Expressway (E3) to Fukuoka.
• Ferry operates daily from Hakata Port to Busan.
• From Busan, follow Namhae Expressway (NHC) to Suwon.
• Plan for rest stops every 2 hours; use highway service areas.

Both countries have high safety standards; however, watch for narrow roads in Japan's mountain passes and aggressive driving in Korean urban areas. Rest zones are excellent: Japan's service areas are clean and have play areas; Korea's rest areas feature arcades and often pet parks (on-leash). For family suitability, plan stops at places like the Uminonakamichi Seaside Park (Fukuoka) or Busan's Taejongdae cliffs.

Fatigue management: take a break every 2 hours; the ferry ride itself is a restful interlude. Notable off-route spots: the Akiyoshido Cave (Japan's longest) is a 30-minute detour from Yamaguchi; the Hahoedang Village in Suncheon is a hidden gem. For pets, ensure your car is equipped with a crate; many rest areas in Korea have dog runs, but Japanese rest areas often do not.
