Ichikawa slight frostbite, now in BC with all members yesterday. 2nd attack planned, but bad weather so abandoned. Leave BC 24 May and reach KTM 7 June via Biratnagar. Same route as French.

Takeshi Naganuma is seriously ill from 10 May, undergoing treatment at BC and helicopter requested. MP Khanal, MFA - 13 May 74 C5 on 5 May 6900m; scheduled C6 by 9 May and attempts before 13 May if weather good. 2 members [Miyazaki and Azuma] and 2 Sherpas [Ang Phurba and Tenzing] swept 150 feet by avalanche on 8 May 11 pm from C5. 2nd sirdar Tenzing badly injured while others minor. Now sudden bad weather and continous snowfall progress as per earlier plan impossible.

Kawase, Hashimura & Obara - 27 Feb 74 Tomorrow all leave by bus and truck to Dharan. 2-3 days to Dharan. Caravan starts 3 or 4 March and takes about 16 days to 20th base camp. If crevasse don't prevent, will use 1962 French route. Summit day 5 May (in Japan is holiday for boys). Hope put all members on summit in 3 parties (perhaps not Dr. although climber but maybe stays in C3). Mikio Kawase, Tokyo - 22 Feb 74 Seijo Univ Jannu Expedition 1974 7 today - total 9. Leave KTM after 7 days to Biratnagar by truck, 1-1/2 days Caravan starts 3 March, 2 weeks to BC at 4500m on Yamatari Glacier. 20 March start climbing. 6 high camps, C6 at 7300m. Route: maybe both French expedition route via Yamatari Glacier and South Ridge. Summit about 5 May, hope all members summit. 14 Sherpas and 6 local porters. C3 to C4 and C6 to top difficult because very steep C3-C4 and ice board and overhang C6 -> summit.
