Keiichi Iwasaki, 36, left his Japanese home in 2001 with just 160 Yen ($2) in his pocket after becoming bored with his air-conditioning job, the UK's Telegraph reports.

After cycling the country for a year he decided to extend his journey to South Korea and, eventually, 36 other countries.

During his trip Mr Iwasaki was attacked by a rabid dog in Tibet, robbed by pirates and was even arrested in India.

He cycled over 45,000 kilometres during his marathon adventure and become the first Japanese man to climb Mount Everest from sea level without using any transportation.

Mr Iwasaki said he raised funds from performing tricks, and only his “strong will” has kept him on his bike.

He chose to avoid air travel and opted for cycling or ferries for transport in order to soak up the atmosphere.

''I didn't want to use aeroplanes because I wanted to see and feel everything with my own skin. With bicycle, I can always feel the air and atmosphere of the place.''

Mr Iwasaki is in Switzerland and hopes to climb Mount Blanc, Europe’s highest peak, before travelling to Africa and the US over the next five years.

He plans to write a book about his adventure.
