Kangbachen Attempt. A post-monsoon expedition of Rikko University, Japan, was led by Yoshikuno Sakai and Takeo Yamanoi. They attempted the northwest face from the Ramtang Glacier. After continuous snowfall for 60 hours, the route beyond Camp IV (21,500 feet) became impossible. They made four attempts for the summit, all of which were repulsed by heavy snowfalls.
