Tsunoshima Bridge and Hagi Castle Town — Yamaguchi's Scenic Views and History

Yamaguchi Prefecture, at the westernmost tip of Honshu, rewards travelers with two destinations of extraordinary character: Tsunoshima, a small island linked to the mainland by a bridge stretching straight over emerald-blue sea, and Hagi, a castle town that produced many leaders of the Meiji Restoration. Combining these two sights, where natural beauty and history are concentrated, makes for a journey that fully savors the appeal of Yamaguchi.

Highlights

Tsunoshima Bridge connects the mainland with Tsunoshima Island floating in the Sea of Japan, running about 1,780 meters in total length. It opened in 2000, and at the time boasted one of Japan's longest lengths as a toll-free island-connecting bridge. The sight of the bridge running straight over cobalt-blue clear sea looks like a tropical resort and is popular as a location for commercials and dramas. It is known nationwide as one of Yamaguchi's signature scenic spots.

Hagi flourished as the castle town of the Choshu domain. Its townscape, where white-walled and namako-walled samurai residences survive as they were, is registered as a World Heritage Site. Shokasonjuku, where Yoshida Shoin educated the future leaders of the Restoration, and sites linked to Takasugi Shinsaku and Ito Hirobumi are scattered about, drawing history fans as the land that produced the driving force of Japan's modernization. Because the castle town's street divisions remain from that era, walking with an old map in hand is a pleasure unique to Hagi.

Seasonal Enjoyment

Tsunoshima Bridge looks best in early summer to summer on clear days, when the sea shines its bluest. Strolling Hagi's castle town is comfortable through all four seasons: spring cherry blossoms add color to the white-walled streets, and in autumn you can walk the quiet lanes at leisure. Winter brings fewer crowds and a chance to savor the calm, atmospheric mood of the castle town. Tsunoshima's white sand beaches also show different faces with the clear air of each season.

Practical Travel Notes

Tsunoshima Bridge and Hagi are more than an hour apart by car, so touring both in a day is realistic by rental car. On Tsunoshima, across the bridge, there is a lighthouse and white-sand beaches you can walk to from the parking area. Hagi's castle-town sights cluster within walking distance, so a rental bicycle makes for comfortable exploring. Hagi ware ceramics and sweets made with summer citrus are popular standard souvenirs. Parking at Tsunoshima's viewpoints gets crowded in the tourist season, so visiting with time to spare is wise.

A Word of Advice

The finest view of Tsunoshima Bridge is from the Amagase Park observation deck before you cross. After crossing, enjoy walks at the lighthouse and beaches as well. In Hagi, walking the white-walled lanes while comparing them with an old map lets you imagine the era when the Restoration leaders passed through. It is a luxurious trip that savors two sides of Yamaguchi, scenery and history, at once.
