C5 called Otaki camp. 3 members started from Otaki camp 8:30 am including Otaki (Takeda and Kobayashi also), arrived final ridge border line between Nepal and Tibet about 11:30 am. Otaki 11:30 am getting tired and since ridge not so steep but long snowfield they take rest at 7750m. Takeda leader of party thought too late in day reach summit that day and considered returning to Otaki camp, but better explore route to summit. Takeda went 100m away to see; suddenly Otaki slipped, fell 2000m into Gyachung Kang glacier in Tibet. Very very steep where Otaki fell; nearly 2000m straight down, so unable climb down. Couldn't see body because of overhang. Kobayashi little below Otaki, who was resting. So why fell, cannot say. All members well throughout except Otaki fatal accident. Sherpas of Cho Oyu said German expedition coming after 3-4 days; met then 1 day below Namche. Kikuchi - 19 June 64 Arrive KTM 5 pm with Machida. Left 8th morning, all members; these 2 came quickly to meet Otaki's brother and Mainichi man. Rest will come about 23rd with Thakur. Otaki fell on Tibetan side and impossible recover because in Tibet; no one saw him fall. 11th morning Machida and Yasuhisa also reached summit. Most difficult: C4 to C6 very steep; around C5 avalanches also caused fear; avalanche actually went over tents sheltered under crevasse. 200m from summit very difficult rock climbing, so had to dump heavy oxygen cylinder which threatened throw him off balance.
