Mount Tate (立山, Tate-yama, IPA: [tateꜜjama]), also known as Tateyama, is a mountain located in the southeastern area of Toyama Prefecture, Japan.

[2] Tateyama consists of three peaks: Ōnanjiyama (大汝山, 3,015 m), Oyama (雄山, 3,003 m), and Fuji-no-Oritate, (富士ノ折立, 2,999m)[3] which form a ridge line.

However, located along the ridge and plateau, about 2 km (1.2 mi) west of the summit, there is a small andesite-dacite stratovolcano.

At the base of the mountain is the town of Tateyama which is accessible by train from the prefecture's capital city, Toyama.

Public transportation takes climbers and tourists as far as the Murodo Plateau Station at an elevation of 2,450 m (8,038 ft), where individuals may climb to the peak on foot.
