This mountain is located in the south of Bōso city and has an altitude of 336m. This mountain with exposed rock is a rare sight in Bōsō where there are numerous gentle-sloping mountains, and it is the only mountain in all of Chiba whose name includes the word “valley”. There are also ropes and chains within the mountain trail; it definitely gets one into a mountain climbing mood. The summit boasts a 360 panoramic view from the neighboring Toyama and the highest mountain peak in Chiba prefecture, Mt.Atago, to Tokyo Bay and the Izu Peninsula. How about enjoying the amazing rocky mountain view at Iyogatake, the mountain also known as “Bōsō’s Matterhorn”?
