Aconcagua and Patagonia. The joint expedition of Nagoya University and the Tokai Branch of the Japanese Alpine Club was led by Kentaro Takagi and composed of Kunitoshi Ishiwara, Shigeru Ando, Tetsuo Ando, Toshiyasu Takai, Takashi Nakaseko, Makoto Hara, Kazutoyo Hashimura, Shoko Ichikawa, Kenji Yanyu, Akihiko Kuroyama, Yoshihiro Oguri and Mitsumasa Takada. On December 30, 1965 deputy-leader Ishiwara reached the summit by the normal route. The south-face party established Base Camp at Plaza Francia on January 16 at 13,800 feet, Camp I on the 25th at 16,750 feet, Camp II on February 2 at 19,000 feet and Camp III on the 18th at 20,650 feet. On February 24 Hashimura, Hara, Ichikawa and Kuroyama completed the difficult ascent after a bivouac above Camp III. The route taken was almost the same as that of the French first-ascent party. It was the third ascent of the route, following the Argentine ascent by about a month. In March the expedition divided into three groups, climbing at Bariloche, exploring near FitzRoy and climbing Cerro Olivia in Tierra del Fuego.
