Nanga Parbat Attempts and Tragedy. Three Japanese expeditions unsuccessfully attempted to climb Nanga Parbat. Tsuneo Hasegawa and three others climbed to 24,600 feet on the 1976 Schell route on the southwest ridge before giving up. Hasegawa returned in October to make a solo attempt on the 1970 Rupal route on the south. He set out on October 20, bivouacked at 5900 and 6900 meters. Frequent snowfalls slowed his progress. On October 30 he dug a snow cave at 7650 meters but the summit try the next day was unsuccessful because of dangerous snow conditions. Ten climbers led by Tateshi Sudo failed at 25,925 feet in an alpine-style attempt on the Diamir Face. An expedition consisting of Fuji Tsunoda, Shigeo Hida, Nobuyuki Imakyurei and Takashi Kogure attempted the 1970 German route on the Rupal Face. They had set up Base Camp on May 28 and had placed four high camps by June 26, Camp IV being at 24,125 feet. After a rest in Base Camp, they climbed back up to Camp III at 22,000 feet on July 6. The radio message to their liaison officer that night was the last heard from them. It is presumed that they perished in an avalanche.
