With a symmetrical T-shaped profile, the stylish Kamiiwato bridge is another high flying beam bridge in the Takachiho Gorge region of Japan’s Miyazaki prefecture. The central pier is either 111 or 104 meters tall making it one of the tallest in Japan. The two main spans are 443 feet (135 mtrs).

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. The asymmetrical arch has an unusually high rise of about 164 feet (50 mtrs) making for a steep rib section of 58 degrees where it meets the foundation.
