Route Notes	Letter from Ikeda - in 1982 Three members were killed in Langshisa Ri in 1973 were, Mitsuyoshi Oshitani (30), leader of the reconnaissance party of Seto Suinan Sangakukai club party (5 men), deputy leader Manabu Kato (22) and Shiniichi Suzuki (25). They were assaulted by an avalanche on Langtang Ri on Oct 19, 1973. The body of Kato only was found, but two others were missed in the snow avalanche.
