Osaka to Takamatsu Road Trip: Bridges, Art, and Hidden Gems

Crossing the Seto Inland Sea on the Seto Ohashi Bridge, you'll drive over 13 kilometers of double-deck spans that connect Honshu to Shikoku; the bridge's lower deck carries both a railway and a roadway, an engineering marvel completed in 1988.

This route covers approximately 190 kilometers and typically takes 3 to 3.5 hours without stops. Whether it's worth driving depends on your appetite for coastal scenery and island-hopping—a train ride is faster but misses the freedom to explore.

Roads are well-maintained with clear signage in Japanese and English; service areas every 30–50 km provide restrooms, restaurants, and convenience stores. Plan a break at the Banshu service area, which has a playground for children and a dog run for pets—pets are allowed in service areas but not inside restaurants.

For families, the Shikoku Mura village near Takamatsu offers traditional buildings and crafts, and the Tamamo Park has a playground with castle views. To manage fatigue, pull over at any of the rest areas; open-air rest spots along the coast offer scenic views and fresh air.

Hidden off-route spots include the Yashima temple complex, reachable by a detour uphill, offering panoramic sea views without the crowds.

The route frames the Seto Inland Sea with its thousands of islands, and the area enjoys a mild Mediterranean climate with low rainfall—autumn and spring offer the clearest views. The region is part of the UNESCO Global Geopark, recognized for its geological diversity.

Along the way, stop at the roadside station Sayo (道の駅 佐用) for local produce, then detour to the Fukuyama area for a bowl of famous Fukuyama ramen, known for its soy sauce base and tender chashu. Local fishing villages sell fresh octopus and sea bream directly from small markets.

Start from Osaka's Hanshin Expressway, merge onto the Kobe-Awaji-Naruto Expressway, then take the Seto Chuo Expressway over the bridge. Tolls for the full route total roughly ¥9,000, and fuel costs about ¥3,500 for a standard sedan with current prices around ¥160 per liter.

• Exit at Takamatsu Chuo IC for easy access to the city center.
• Consider the Kansai Expressway Pass for unlimited expressway travel in the region—saves money if you're making multiple stops.
• Parking is ample in Takamatsu, with city lots charging about ¥200 per hour.
