The “Oboke and Koboke Gorges” were made by the rapid current of the Yoshino River crossing Shikoku Mountains over a period of 200 million years. These gorges are eight-kilometer long and boast a breathtaking landscape looking like soaring marble sculptures – I never saw anything like this before.
We did a river cruise to experience the “canyon” first hand. The water is famously Yoshino river green and the boat takes you 4 kilometers through this beautiful rock landscape. It doesn’t take more than 30-40 minutes.
The Oboke Gorge has beautiful rocks and a V-shaped valley, which can be observed closely and shows how the Japanese archipelago has been formed. It makes the gorge a valuable place and was designated as a national monument by the government.
The trip here is 2 hours from Kochi, so we did a little lunch before going on the boat. At the cruise boat pier there is a small restaurant offering classic Japanese meals that you order via a machine. So fun. The restaurant is 80 meters above the river and offers an amazing view.
To go there Google Obokekyo Mannaka, then you will be let straight to it. The river cruise and restaurant are open 7 days a week almost all year around.
