     Mount Everest is the highest mountain in the world. It is in the Himalayan Mountains between Nepal 

and China, and it is 8 900 meters high. Sir Edmund Hillary from New Zealand and Tenzing Norgay 

from Nepal were the first people ever to climb Mount Everest. They climbed it in 1953. Men from 

several different countries climbed it after that.

     Jumko Tabei, a Japanese from Hokkaido, was the first woman to make this difficult climb. A 

Tokyo newspaper television organized the climb in 1975. They chose fifteen women from 

mountaineering (登山) clubs to go to Nepal. The group climbed for several days. Then there was an 

avalanche (雪崩). The heavy ice and snow injured ten of the women. They had to stop climbing, the 

other five women continued.

     Only Ms. Tabei was able to climbing the last 70 meters. She was standing on the top of the world. 

She was the first woman there.

     Ms. Tabei was 35 years old at the time. She is 1 meter 50 centimeters and weighs 42 kilograms. 

She says that she is an ordinary housewife. She started climbing mountains in 1960. She climbed 

every mountain in Japan. Then she climbed Mount Annapurna, another high mountain in the Himalayas. 

Finally she climbed the world's highest mountain.

     When she reached the top, she thought, "I'm at the top and I'm glad that I'm at the top." Then she 

climbed back down the mountain.
