| Route Notes | NHK Everest Expedition - 3 June 2011 led by Manabu Hirose The expedition first went for an acclimatization climb of Lobuche East. All five members and five Sherpas climbed to the mountain's east shoulder on 15 April. They then moved to their Everest BC on the 19th. The five members and ten Sherpas left C4 for the top at 10:50 pm on the 24th of May and were on the summit at 9:30 am on 25 May. They returned to to C4 at 3:52 pm that day, descended to C2 on the next day, and were back in BC on 27 May. The members used oxygen in C3 to the top to and in C4; the Sherpas used it from C4 to the summit to C4. None of the members had any health problems, but one Sherpa, Pemba Nuru, had a toothache: he went down to the dental clinic at Namche, had his tooth extracted, and returned to the expedition. Lhakpa Nuru's toes were slightly frostbitten.
