Located in Mikuni Mountain range on the border of Gunma and Nigata prefecture. The summit has twin peaks Tomanomimi (トマノ耳) and Okinomimi (オキノ耳). Known as “Mountain of Evil”. It’s not because the handful of steep cliffs and rocky sections, it’s not because of multiple sections with chains and ladders to help you on the narrow ridge line, is not the elevation (1977M), and not the bells along the trail to scare the bears – it is sudden and unpredictable change of weather that claimed over 800 lives.
