It is said that he who climbs Mount Fuji once is a wise man, while he who climbs twice is a fool.
But cyclist Ollie Blackmore is throwing caution to the wind as he hopes to tackle it no less than 25 times.
The 41-year-old from Norwich is aiming to set several world records when he takes on the challenge next week.
It will see him ascend more than 150,000ft over a nine-day period as he travels up and down Japan's tallest mountain by bike.
During that time he will be at the mercy of its unpredictable weather conditions as he attempts to complete it during typhoon season.
Mr Blackmore, who lives on Park Lane, said: 'Last time I did a challenge in Japan I faced all sorts of problems.
'I had a crash, mechanical problems with my bike, and got lost... It was a nightmare.
'But every day I came through and the motivation to pull through is what kept me going.
'I have no idea what challenges will be put in my way this time, but I will tackle them with the same gusto.'
He is taking on the challenge to raise awareness and more than £6,500 for the Dolphin Project - a charity dedicated to ending their slaughter and exploitation.
Mr Blackmore - a managing direction of a digital agency - completed a 2,316km cycle challenge around the country last year for the organisation. This time, he is hoping to set the world record for the most ascents up Mount Fuji on a bike in nine days, and the fastest ascent up all four road climbs on the mountain in 24 hours.
During the challenge he will carry 15kg of kit on his road bike in preparation for the harsh conditions along the way.
Mr Blackmore added: 'The difference in temperatures will be a challenge in itself, as well as carrying kit for such drastic changes in weather conditions whilst being agile enough to tackle the huge amount of climbing every day.'
He will be leaving for Tokyo on Monday and will start the challenge on Thursday.
