A group of three climbers from Hokkaido, including a 34-year-old woman, on Wednesday reached the summit of Mount Everest, according to a local mountaineering association.
Ruchia Takahashi, from Sapporo, became the fourth Japanese woman to scale the 8,850-meter peak in the Himalayas.
The Japanese group and two Sherpas reached the top after leaving their final camp at 8,200 meters on the north route Wednesday morning, the association said Thursday, adding that the weather was reportedly fine at the time.
The three climbers left Japan in early March and arrived at the foot of the mountain in mid-April, following highland training in Nepal, it said.
On May 16, 1975, Junko Tabei became the first woman to scale the world's highest peak.
Meanwhile, the Nepalese Tourism Ministry said a Nepalese woman scaled Mount Everest on Thursday, becoming the second woman from the Himalayan kingdom to reach the summit.
Lhakpa Sherpa, 27, stood atop Mount Everest at 6:30 a.m., after a nine-hour march from a camp.
A former high-altitude cook, Lhakpa is expected to become the first Nepalese woman to return from the summit alive.
The first Nepalese woman to climb Mount Everest, Pasang Lhamu Sherpa, died during her descent in April 1993.
Lhakpa was accompanied to the summit by three Sherpas who had previously climbed the mountain.
On Feb. 1, the Nepalese government rejected reports claiming that the height of Mount Everest is 8,850 meters, insisting that the official height of the mountain will remain at 8,848 meters.
