Route Notes	Correct route for 1975 Spring Japanese on Dhaulagiri I was: South Ridge, not South Pillar (according to Yves Pollet-Villard, Nov 1978). Amemiya - 14 May 75 All in KTM. 11 arrive yesterday. 1st group leave 25 or 30 May; others 20 June after some go trekking others sightseeing. 1st group of 3 including leader. Numao and Imura ashes slowly sent ot Japan. C3 at 5800m on 18 March highest camp. 6200m highest point reached by Kazuharu Kohara, Takashi Maruyama, Yasuji Kato on 19 April. Started climbing 10 April again. Could not make C4. Route very difficult, weather bad, most Sherpas did not want to go on but these not main reasons: leader decided. South Pillar route is possible by some climbing route. No other accidents, no frostbite, no yeti. Fatal avalanche during night 25/26 March [1 am]. All 3 tents covered in C1 with 11 men. No one injured besides 5 killed. Heavy snowfall on 25 March. Ranjan Stopped climbing again after leader returned from quick trip to Tokyo where he received orders to stop. Most members wanted to keep climbing. MP Khanal, MFA - 10 April 75 Abandoned expedition; decision from Tokyo received yesterday. All bodies recovered next day after accident and cremated at BC. Leave BC next week for KTM. All climbing suspended since 26th March and all at BC. MP Khanal, MFA - 27 March 75 C3 established 18 March at 5800m by Seiji Shinizu, Motoyashi Tanaka and Dawa Norbu. MP Khanal MFA - 20 March 75 C2 established on 10 March at 5270m by Kohara, Maruyama and Kashima. Akira Takahashi - 24 Jan 75 Was here with Manaslu expedition. All members arrive KTM 15 Feb on TG Base camp on Myagdi Khola at 3500m Leave KTM 12 Feb by road to Pokhara; in Pokhara 3-4 days to arrange porters; leave Pokhara about 15 Feb by bus and then foot for 15 days.
