| Route Notes | Toriumi - 30 May 81 All members arrive yesterday except leader who left early for Japan (flew ex-Lukla, rest trekked to KTM). C4 15 April at 6600m, other ministry camp data and summit correct Between C4 and summit: bad weather and route making Route = SE Ridge of 1954 and 2 Japanese expeditions Autumn 1980 and Winter 1980-81 Only 3 members to top because some altitude sickness, some not so strong and weather not good. Oxygen used 30 minutes before going to sleep in C4. No accidents, frostbite or avalanche. Did not climb other peaks. Route very easy BC to C4, but above C4 difficult: very big crevasses and snow very soft (would be harder in post monsoon).
