Two Japanese balloonists successfully flew over the 8,125-meter Mount Nanga Parbat in Pakistan on Saturday, their supporters said.

During a three-hour flight from the northeastern Pakistani town of Chilas to a base near the Pakistan-India border, 50-year-old Michio Kanda and Hirosuke Takezawa, 38, traveled at about 35 kph in their hot air balloon named "Mambo," or globefish.

"It's great looking at Mount Nanga Parbat while flying," one of them said.

Kanda and Takezawa, both from Saitama Prefecture, spent about one week waiting for favorable winds.

They hold world-records for the hours they have spent airborne in hot air balloons, and have flown over the Himalayas and the East China Sea.

Their latest flight comes two years after they abandoned their attempt to fly over 8,611-meter K2 -- the world's second-highest peak -- due to poor weather conditions.
