Hiroshima to Gyeongju Road Trip: Best Stops & Guide

The drive from Hiroshima to Gyeongju spans nearly 700 kilometers (435 miles), crossing the Kanmon Straits and traversing the rugged Chugoku Mountains before following Korea's southern coast.

This route, historically significant as a departure point for Korean envoys, now offers a mix of expressways and scenic coastal highways.

Here's a comprehensive guide to planning this epic journey, with all the essential facts you need.

Both Japan and Korea have excellent road networks with high safety standards. In Japan, speed limits on expressways are typically 80-100 km/h, while in Korea they range from 90-110 km/h. Drive on the left in Japan, the right in Korea – a major adjustment.

For families, both countries offer well-equipped rest areas with playgrounds and clean restrooms. In particular, the Kanmon Bridge rest area near Shimonoseki has a small aquarium, and Korean service areas often feature children's play zones.

• Pet-friendly framework: Japan's ferry and Korean hotels have varying pet policies; research pet-friendly accommodations in advance, as options are limited.
• Infrastructure safety: Well-marked signage and frequent lighting are standard; night driving is generally safe but watch for deer in rural Japan.
• Fatigue management: Plan to rest every 2 hours; designated rest areas are plentiful on both expressways, with cafes and snack bars.
• Hidden off-route spots: Just off the San-yo Expressway, visit the Akiyoshidai Quasi-National Park in Yamaguchi, with its limestone plateau and Akiyoshido Cave; in Korea, detour to Guryongpo, a historic port town near Pohang, for quiet beaches.

Local commerce: Besides oysters, try Hiroshima-style okonomiyaki and Korean bulgogi; both are regional specialties.

Driving the entire way involves two international border crossings and a ferry, so careful planning is essential. The total driving time, excluding stops and the ferry, is about 5 hours, but factoring in border procedures and waiting times, plan for at least 9-10 hours on a single day.

• Fuel costs: expect to pay roughly 8,000 yen (about 55 USD) for the Japanese leg and 50,000 KRW (about 40 USD) for the Korean leg, depending on your vehicle's efficiency.
• Ferry ticket prices for a car with driver start at 20,000 yen each way; book in advance.
• You'll need an International Driving Permit (IDP) for Japan and a separate IDP valid for Korea; check requirements before departure.
• Tolls on Japanese expressways will total around 10,000 yen; in Korea, tolls are much lower, about 10,000 KRW total.

Japan's San-yo Expressway hugs the Seto Inland Sea, offering glimpses of misty islands and terraced fishing villages. In contrast, Korea's coastal roads along the southern shore present dramatic cliffs and pine forests.

Along the way, you'll pass through agricultural heartlands where local farmers sell seasonal produce at roadside stands – look for Hiroshima's renowned oysters (available from October to March) and Busan's fresh seafood markets.

• Natural landscapes: The Chugoku Mountains in Japan are a lush green corridor, while Korea's Gyeongju is known for its scenic low mountains and coastal plains.
• UNESCO World Heritage Sites: Hiroshima's Atomic Bomb Dome and Itsukushima Shrine are on the itinerary, as are Gyeongju's historic areas, including Bulguksa Temple and Seokguram Grotto.
• Climatic conditions: Expect humid summers with heavy rains (June-July) in both countries; autumn (October-November) offers mild temperatures and vibrant foliage, ideal for driving.
