Yuichiro Miura, an 86-year-old Japanese alpinist and professional skier, has given up on his attempt to conquer the 6,959-meter Mount Aconcagua, the highest peak in South America, on doctor's orders, his office in Tokyo said Monday.

"I was confident that I could climb to the top, but decided to follow the doctor's order," Miura was quoted as saying by the office. The alpinist, who had reached the camp at Plaza Colera, at an altitude of about 6,000 meters, is in good health and has already descended the mountain, the office said.

Miura, who became the oldest person to conquer Mount Everest at age 80 in 2013, had been waiting at Plaza Colera since Friday local time for favorable weather conditions. He summited Aconcagua, whose peak is located in Argentina, in 1985.
