As the 15th highest peak in the world, it is also the co highest peak (with Gasherbrum III) that is not an eight-thousander; hence, it is far less well-known than the lowest of the eight-thousanders, which are only about 100 m (328 ft) higher.

The peak's lack of significant prominence (700 m) also contributes to its relative obscurity.

The mountain was first climbed on April 10, 1964, by Y. Kato, K. Sakaizawa, Pasang Phutar, K. Machida and K. Yasuhisa.

The north face was first climbed in 1999 by a Slovene expedition and was repeated by Yasushi Yamanoi in 2002.
