A beautiful stone bridge built by wealthy merchants during the Edo period. Designated as a nationally important cultural property, it continues to captivate people with its unchanging appearance.
Kokan-kyo Bridge, completed in 1824, was the largest stone bridge in Japan at the time. It was built by local wealthy merchants who invested their private funds to overcome a difficult part of the road connecting Mie town, which was part of the Usuki Domain, and Usuki Castle Town. 'Kokan' means a rainbow over a valley stream, and as the name suggests, it draws a beautiful arch. The bridge, which uses many cut stones of Aso welded tuff, is both sturdy and beautiful. It was designated as a nationally important cultural property in 1999. Automobiles were allowed to pass until 2003, but now only pedestrians are allowed. The area around the bridge is designated as the Oita Bungo-Ono Geopark, where you can enjoy the rich natural scenery.
