Mount Tate, Sacred mountain in Toyama Prefecture, Japan.

Mount Tate is a sacred mountain in Toyama Prefecture that rises to 3015 meters and consists of three distinct peaks forming a long ridge line in the Hida Mountains. The steep rock faces and deep valleys are laced with snowfields that remain visible on the northern slopes well into summer.

Saeki no Ariyori completed the first documented ascent in the 8th century and made the mountain an important destination for Buddhist ascetics. Over the following centuries this place became a major pilgrimage center with trails and shrines built along the entire route.

The kanji 立 in the name means "standing" or "outstanding", not simply upright posture. The summit's Oyama Shrine is one of three linked shrines: the peak sanctuary, the prayer hall at Ashikuraji and the lower shrine at Iwakuraji. A custom persists of carrying a pebble from the Katakai River to offer at the top.

The Tateyama Kurobe Alpine Route provides access from April to November and starts from either Toyama Station or Ogizawa Station. In dry weather the trails are easy to walk but hikers should bring warm clothing and sturdy footwear as temperatures at altitude can remain cool even in summer.

The glaciers are visible ice bodies, not hidden ones: the Gozenzawa Glacier on Oyama's east slope runs about 700 m and covers roughly 0.1 km², feeding the Kurobe River. The smaller Kuranosuke Glacier, in Kuranosuke Cirque, is the only one of Japan's seven glaciers that ordinary hikers may walk onto.
