| Route Notes | Ishibashi led all the pitches, so hard climb for him; the other two were not in good condition. Descent very slow because Shibuya developed serious altitude sickness. The seven-man Sangaku Doshikai party of Tokyo, led by Naoe Sakashita, climbed three 6000ers in the Khumbu Himal in alpine-style pushes. They were: the South Ridge of Cholatse, the SE Face of Tawoche, the W Face and the SW Ridge of Ama Dablam. |
| Accidents | Shibuya got altitude sickness after summit and lost his sense of balance (he recovered) |
