Cho Oyu and Shisha Pangma, 1988. On page 283 of AAJ, 1989, it lists an ascent of Cho Oyu, by Noburu Yamada and three other Japanese on November 6, 1988. Actually there were two other Japanese: Teruo Saegusa and A. Yamamoto. Along with O. Shimuzu, they had previously, on October 24, 1988, climbed the normal route on Shisha Pangma. These ascents were the eighth and ninth 8000ers for Yamada. Tragically, Yamada died in late February on Mount McKinley.
