Smt 26 May by Takeuchi at 5:30 am.

Takeuchi left C3 at 1:30 am. Weather was perfect and calm. It was very warm. The trail was broken trail to C4. From C4 he had to break trail, however, it was not very deep. He was going slowly due to fatigue. Cleo Weidlich and her Sherpa caught up with him and they alternated breaking trail. He spent about five minutes on the summit due to high winds and the time of day. He descended to C4 (7500m) and as he did not have a tent there, he bivouacked. He got there at about 10 pm.

On 27 May he descended to BC.

Nakajima reached 6800m on 24 May. He felt altitude sickness and Hirose made him turn back to C1.

They left BC on 30 May.

During their expedition, they found the Yeti airplane, which crashed in 1960. It was at about 5200m near the Dampus Pass.
