Have you heard of Kikuchi Keikoku (Kikuchi Gorge) in Kumamoto Prefecture? Speaking of a beautiful mountain stream in Japan, I first associate it with the Oirase stream (Aomori prefecture) in the Tohoku region of Honshu. The Oirase stream has become more and more popular in recent years, but the Kikuchi Keikoku is second to none. Those who enter the Gorge will be fascinated by the beauty of this stream. The gentle world created by Aso is spreading in the Kikuchi Keikoku. On this page, I would like you to have a virtual experience of the world of Kikuchi Keikoku.
