Sado Ichi (Osado Circuit)

Updated on2026/2/16

For those reluctant to take on the full Sado Circuit at over 200km first up, we recommend starting out with the 132.8km Osado Circuit. It is used as the B-course for the Sado Long Ride 210 and combines the Kosado mountain route, where the Japanese crested ibis (toki) and numerous historic ruins can be seen with the Osado Coast section. Take in the jawdropping views of the wild Sotokaifu Coast and the serene scenery of the Kuninaka Plain, home of the toki.
