Seiun bridge opened in 1984, the same year as the nearby Aya Teruha footbridge. At the time they were Japan’s two highest bridges. Seiun is now one of 8 bridges in the Takachiho gorge region that exceed 328 feet (100 mtrs) in height. The bridge was a favorite of at least one of Japan’s earliest BASE jumpers.
There is no other region in Japan that has as many high bridges than the Takachiho Gorge Scenic Area of Miyazaki Prefecture. Within a distance of just 30 kilometers the Gokase and Iwato River canyons are crossed by no less than 15 high bridges.
Several of these spectacular crossings were the highest in Japan including Tensho, Seiun and Unkai Bridges. The Takachiho Railway Bridge is still the highest railway crossing in Japan even if it not longer operates with regular trains.
