Mount Tatsuiwa

立岩

Nanmoku, Gunma · Elevation 1,265 m

A 1,265 m rock peak standing like a folding screen above the Hoshi-o hamlet of Nanmoku Village, Gunma. Its sheer west wall and the jagged rock ridge to the east have earned it the nickname "Dolomites of West Jōshū." The route is known for sustained difficulty — long scree slopes, chained sections, and a narrow exposed traverse known as the "crab crawl" — and it is included on the Gunma Hyakumeizan and Kantō Hyakumeizan lists, among others.
