Mount Tanigawa is a 1,977-meter peak straddling the border of Gunma and Niigata prefectures, recognized primarily for its hazardous, vertical rock faces on the Ichinokurasawa gorge side. Known locally as the 'Mountain of Death,' it holds the Guinness World Record for the most fatalities of any mountain globally, with over 800 recorded deaths since the 1930s. The mountain features two distinct peaks, Tanigawadake-Yakushi and Tanigawadake-Tomanokami. While the summit is accessible via the Tanigawadake Ropeway, the technical climbing routes on the north face attract elite mountaineers. Sudden weather shifts and high-velocity winds are characteristic of this range due to its position on the divide between the Sea of Japan and the Pacific Ocean. Experienced hikers frequently utilize the Nishikuro Ridge, a steep and challenging trail, to reach the summit.
