Mountain climber Hirotaka Takeuchi has become the first Japanese to conquer the world's 14 highest peaks above 8,000 meters, according to his supporters in Japan.

The 41-year-old professional climber achieved the long-held goal on Saturday by summitting 8,167-meter Dhaulagiri, the world's seventh-highest mountain, at about 5:30 p.m. Nepal time.

The feat came just a week after Tamae Watanabe, 73, became the world's oldest woman to successfully climb the tallest peak, 8,848-meter Mount Everest.

Takeuchi, a Tokyo native who has been climbing since childhood, first topped an 8,000-meter mountain in 1995, when he scaled 8,463-meter Makalu, the fifth-highest peak.

He followed that up in 1996 by scaling Everest and 8,611-meter K2, the second-highest peak.

While climbing Pakistan's 8,035-meter Gasherbrum II in 2007, Takeuchi was badly injured in an avalanche and had to be rescued. After surgery and rehabilitation, he took on the same mountain just a year later and made it to the top.
