The bridge was originally operated manually by hand cranks before its 1960 electrification.
The rotating mechanism allows the bridge to pivot 90 degrees to allow boat passage.
It connects the cultural area of Monju to the famous Amanohashidate sandbar.
The bridge span is supported by a central pillar hidden beneath the water level.
It is a central landmark in the Aso Bay waterway system.
Kaisen Bridge is a rare 'revolving' bridge located in Miyazu, Kyoto, that connects the mainland to the sandbar of Amanohashidate. When large vessels need to pass through the canal connecting Miyazu Bay to Aso Bay, the entire central span rotates 90 degrees to clear the waterway. Originally built as a hand-operated bridge in 1923, it was upgraded to a modern electric-powered mechanism to accommodate boat traffic. The bridge serves as a vital pedestrian path for those traveling between the Chion-ji Temple and the Amanohashidate pine-covered sandbar. Its mechanical movement is a notable piece of civil engineering that remains fully functional for daily maritime operations.
From the canal banks on either side of the bridge for a clear view of the rotation mechanism.
Wait near the bridge railing to witness the 90-degree rotation when boat sirens sound.
Combine your visit with a walk across the entirety of the Amanohashidate sandbar.
Visit the nearby Chion-ji Temple immediately after crossing the bridge.
Do not attempt to cross or linger on the bridge structure once the warning sirens sound and the rotation process begins.
Operates daily; the bridge rotates intermittently throughout the day depending on local boat traffic schedules.
