Route Notes	C1A (deposit camp really) High point at NW Face. Summit bid: 1st on 29 Aug, started 5:30 am Chinese time by Suda, Fukada, Okabe & 2 Sherpas (Dawa Tenzing and Ang Dorje); reached 7600m, site for C3 but camps not established. Not on normal route but more direct (like Belgians this summer). Turned back by chest-deep snow and fear of avalanche (Fukuda and Okabe stopped at 7300-7400m). 3 members were climbing on oxygen in order to climb quickly but Okabe had problem with oxygen apparatus (French masks) so turned back. 2nd bid on 31 Aug by Suda, Okabe & Ang Dorje; started 3:30 am from C2 and reached 8050m at 4:00 pm and again too much snow after climbing over snow-slab overhang, which thought was summit. Above this very deep soft snow. Ang Dorje had turned back at 7600m. Again Japanese members climbed on oxygen. Left BC 6 Sept (Sokumi left BC 31 Aug to return to work).
Accidents	Fukushima pulmonary edema; Chandra Gurung (cook) unknown illness at Japanese BC, died at Chinese BC
