Besides the original Japanese ascent, a notable ascent of the North Ridge was the one in 1990 by Greg Child, Greg Mortimer, and Steve Swenson, which was done alpine style above Camp 2, though using some fixed ropes already put in place by a Japanese team.
Osim prvog japanskog uspona, istaknuti su uspon na sjevernoj strani 1990. ostvarili Greg Child, Greg Mortimer, i Steve Swenson, u alpskom stilu iznad Kampa 2, iako korištenjem ponešto pričvršćenih užadi već postavljenih od japanskog tima.
