Takamatsu to Tongyeong: Ferries, Highways & Hidden Gems

Takamatsu (34.35°N, 134.05°E) and Tongyeong (34.85°N, 128.43°E) face each other across the Korea Strait, linked by a 230-kilometer sea route that ferries have plied for decades. But a road trip between them is impossible without a car ferry, as no bridge connects Japan and South Korea. The most practical drive involves a 3.5-hour ferry from Busan to Fukuoka, then a 4-hour drive to Takamatsu—or vice versa.

Before planning, check the how to find the best stops and hidden gems between cities guide. The total drive time, including ferry, is about 9 hours, so budget two days for comfort.

The drive from Fukuoka to Takamatsu passes through Seto Inland Sea National Park, featuring the iconic Great Seto Bridge. Tongyeong is known for its ria coastline and the Hallyeohaesang National Park. UNESCO World Heritage Sites: On the Japanese leg, the Itsukushima Shrine (Miyajima) is a detour, and in Korea, the Gaya Tumuli (nearby Gimhae) are recent additions.

Local commerce thrives on both sides: Takamatsu's Ritsurin Garden and Tongyeong's central market offer regional crafts. Hidden off-route spots include the Iya Valley (Shikoku) and the Bijin Island, known for its stone wall landscapes.

Climate-wise, both regions enjoy mild winters and humid summers; autumn foliage peaks in November, and cherry blossoms in April.

Fuel costs differ: Japan averages ¥170/liter (~$1.10), Korea ₩1,700/liter (~$1.25). The 640-km total road distance consumes roughly 50 liters, costing ¥8,500 or ₩85,000. Toll roads: In Japan, expressways (e.g., E28) cost about ¥5,000; In Korea, the Namhae Expressway (Route 10) charges ₩8,000. Ferry fares for a car start at ¥35,000 one-way.

• Highway quality: Japanese roads are excellent, with frequent rest areas; Korean expressways are well-maintained.
• Border paperwork: You'll need an International Driving Permit for both countries.
• Book ferries in advance during summer.

Both countries score high on road safety indices, with Japan having 3.4 traffic fatalities per 100,000 people and Korea 6.5. Rest zones are plentiful: Japanese SA/PAs every 30 km, Korean rest areas every 25 km. For fatigue, plan a stop every 2 hours.

For families, the Seto Ohashi Memorial Park and the Tongyeong Cable Car are hits. Culinary infrastructure is dense: Takamatsu is famous for Sanuki udon, and Tongyeong for honey bread. Pet-friendly: Many Japanese rest areas allow pets, and Korean rest stops have pet relief areas.

Essential rest stops: Bitchu Matsuyama (Japan) and Jinju (Korea) break the drive nicely. Avoid driving between 2-5 PM on Korean highways due to drowsiness peaks.
