A Japanese mountaineer has led an expedition to the top of Mount Everest to retrieve tons of rubbish littering the slopes of the world's highest peak.
Ken Noguchi led a team of Japanese and Nepali climbers and returned with 500kg (1100lbs) of tins, old tents, food and medicine left over decades by other climbers.
He estimates he has collected some 9,000kg (20,000lbs) of rubbish from Mount Everest during his five trips to the peak.
The peak has been often described as the "world's highest rubbish site".
Mr Noguchi said he will display some of the rubbish in Tokyo and Seoul to raise public awareness about keeping the world's most famous mountain clean.
