Watanabe and Ritemba started their summit push at 9 pm on 11 May from C4. When they reached 8700m at 7 am on 12 May strong wind started picking up and visibility became very poor due to white-out. Many climbers behind them turned around. Watanabe and Ritemba decided to stop and they too turned around [and back] to C4 at 4 pm. Watanabe was suffering from throat infection, and also had vomited several times. The team did not put their own tent at C4. Their plan was to go down to C3 after summit. So they had to spent the night in the tent of Ritemba's brother without sleeping bag. Watanabe said that it was very cold night and oxygen which she was using also ran out. Next day on 13 May Watanabe and Ritemba went down to C2 and the following day to BC. Watanabe's condition was very bad so she was air-lifted to Kathmandu by helicopter; on 16 May she was hospitalized for few days.
