Ôboke and Koboke are the deep gorges formed by Yoshino River.

They are located near the western edge of Tokushima Prefcture, about 90 km west of Tokushima city, about 40 km south of Kotohira town, and about 50 km northeast of Kochi city.

These gorges are in the deep mountain, and Yoshino River flows from south to north.

Ôboke gorge is in the upstream area and Koboke gorge is about 6 km below Ôboke.

Two different names have been given to the gorges, but there are steep rocky cliffs and fast flows of Yoshino River continuously in the section between both gorges.

These gorges have been formed by the erosion of Yoshino River for over two hundred million years.

They been on one of the few routes connecting Seto Inland Sea side and Pacific Ocean side in Shikoku Island.
This section has been a traffic chokepoint since ancient times.

Ôboke has very rough rocks and river flows with a volume of water.
Koboke is narrower, more winding, and faster river flows than Ôboke.

And, it is said that the flowing speed of the river in both gorges is the fastest in Japan.
