On 22nd same three members and Pema Chhumbi went up to 8000m; then storm blew up, so Ishikawa, Kasuno and Tusbosaka turned around to C1 and slept there. Pema Chhumbi went down to ABC.

The team reached 8750m at 5 am on 27 May. There was about half-meter deep snow with the fixed rope buried under snow. The team waited at that point for three hours and decided to go down.
