Mt. Iwahiyama

岩樋山

Nichinan, Tottori / Shōbara-shi, Hiroshima · Elevation 1,271 m

A 1,271-meter peak straddling the border between Nichinan Town (Tottori) and the former Saijō area of Shōbara City (Hiroshima) in the eastern Chūgoku Mountains, joined to neighbouring Mount Dōgo by a broad plateau-like ridge. A two-kilometer grassland saddle stretches between the two summits, lined by long stone walls — relics of Edo-period cattle and horse grazing fields — that locals nickname the "Great Wall". The peak lies within Hiba-Dōgo-Taishaku Quasi-National Park and serves as the standard waypoint on the popular Tsukimigaoka traverse to Mount Dōgo, known for azaleas in early summer and silver-grass in autumn. It is featured in the Hiroshima 100 Mountains guide.
