| Route Notes | BC at CBC/IC on 25 April at 5800m. First summit push started from ABC on 20 May, Ishikawa, Katsuno, Tsubosaka and Pema Chhumbi spent the night at C1 on that day. Next day they went to C2. On 22nd same three members and Pema Chhumbi went up to 8000m; then storm blew up, so Ishikawa, Kasuno and Tusbosaka turned around to C1 and slept there. Pema Chhumbi went down to ABC. Next day members went down to ABC. The team started again on 24 May from ABC. Katsuno, Tsubosaka, Pasang Gelji, Ongda Gyalzen and Pema Chhumbi started from C3 at 8 pm on 26 May in snowfall. The team reached 8750m at 5 am on 27 May. There was about half-meter deep snow with the fixed rope buried under snow. The team waited at that point for three hours and decided to go down. They arrived C1 at 8 pm. Lhakpa's high point 8000m. Leader Hayashi while going to ABC from CBC on 9 May at about 5000m was unable to walk properly. His steps were unbalanced; it happened Hayashi for the first time, so he went down to BC.
