Phabrang South. Tohichi Ohtake led the Tokyo Denki University expedition. After crossing the Rohtang Pass by bus, they reached Thirot Nalla of Lahul via Keron on September 12. After going through the villages of Chokang, Chhogzing, Guhari and Nawinghar, they placed their first Base Camp at 13,000 feet. They then tried an unnamed 19,748-foot peak which stands in a remote corner of the Thirot Nalla. They reached the southwest col after placing Camps I (15,750 feet) and II (17,325 feet) on the north glacier. They were prevented from continuing on advice of their liaison officer because of inner line problems. They then returned and entered the Nainghar Nulla. Base Camp was at 13,600 feet, Camp I at 15,750 feet, Camp II at 17,400 feet and Camp III at 18,500 feet. On October 30 Kunitoshi Iguchi and Tsutomu Mashiko reached Phabrang South (20,145 feet). That same day Ohtake and Namgyal climbed Siri Parbat (19,029 feet). It is wondered if one of the peaks climbed by the Shiga party and by this expedition are not the same.
