Nanga Parbat Attempts. There were several unsuccessful attempts on Nanga Parbat in 1991. Koreans led by Lee Dong-Won were unable to complete the climb via the 1962 German Diamir route. Italians under the leadership of Stefano Righetti reached a highpoint of 7500 meters on the Rupal Face, while Japanese led by Seishi Wada had to give up at 7900 meters on the southeast buttress after spending 75 days in the attempt. Another Korean expedition led by Kim Hyoung-Joo also failed; we do not know which route they tried.
