Summit team and Nukita left C3 at 11:30 pm on 16/05. There were some little traffic jams on the 2nd Step, but otherwise straightforward climb.

They spent about 30 minutes on the summit. They descended to ABC, where they arrived at 7 pm. Motoike arrived at 3 pm.

Nukita reached 8500m (bottom of 2nd Step) when his regulator failed at about 2:30 pm. He was waiting for Hiro and they changed the back-up regulator, but as it was the same model, Nukita was worried that it would happen again. He descended to ABC.
Motoi reached North Col on 01/05. He suffered from low blood pressure. Monica Piris, the doctor of Alpenglow Expeditions, looked at him and told him to go down.

Noriaki reached ABC. He had a heart problem and again Monica Piris told him to go down.
