Itaya Pass is often closed in road traffic information for the outskirts of Fukuoka City. It is a steep mountain pass in the middle of the Sefuri Mountains, created by granite 100 million years ago. I will cross it by motorcycle while looking at the rocks and topography. 🌟Membership registration / @chiri_rider ★Website "Listen to the voice of the contour lines!" http://chiririder.com/ ★Geographic Rider's Twitter (Follow now) / chiri_rider ★Question box (For questions and requests that are not directly related to the video, please go here) https://peing.net/ja/chiri_rider Source of geological map: AIST Geological Survey of Japan "1:200,000 Seamless Geological Map of Japan v2" https://gbank.gsj.jp/seamless/v2.html #Touring #Granite
