He is a self-professed associate of Japan’s  notorious Yakuza who admits that his business interests are somewhat  dubious.

So Morohoshi-san might have been expected to select the most low-profile vehicle money could buy.

Instead, the ‘businessman’, from  Kabukicho, Tokyo’s ‘entertainment  district’ bought himself a flashing neon Lamborghini Diablo.

He is the star of a new mini documentary Underground Hero: Love to Hate Me about the lives of the infamous Yakuza – the  so called Japanese mafia – and their associates.

This is the modified Lamborghini Diablo driven by  Morohoshi-san, from Kabukicho, Tokyo’s ‘entertainment district’ is one of the  stars of a new mini documentary about the chosen ride for associates of the  infamous Yakuza mafia

Given that his business, by his own admission, lies  firmly in a ‘grey area’, this Japanese ‘gangster’ might have been best advised  to pick a car with a low profile. Instead he has chosen a Lamborghini Diablo,  modified in a particularly indiscreet neon fashion

In the film the businessman is seen driving in a variety  of showy modified Lamborghini

Tokyo-based videographer, Luke Huxham, came  up with the idea for the documentary, produced by Maiham  Media, he  said, after seeing ‘questionable looking people driving around in supercars’.

He said: ‘You can’t really just walk up to  these guys and ask them to be  in your film.

‘You don’t walk into Kabukichou after  midnight and start  trying to film people with tattoos all over their bodies  unless you want to have your nose broken.

‘You need to know someone that has a good  relationship with the people in these underground cultures and ask them  to  invite you in for as long as you’re allowed to stay which is usually  not very  long.’

He struck  up a rapport with Lamborghini  fanatic Morohoshi-san, and tailed him with a camera as he mixed with Japanese  bike gangs the Bosozoku, brightly  coloured flashing Lamborghinis and the  Yakuza.

The Yakuza is a collective term given to  Japan’s organised crime syndicates.

It is estimated that the Yakuza has  over  100,000 members spread across the country in different gangs, but  together they  make the largest organised crime group in the world.

The gangs, along with Osaka street racers and  Kanto area Bosozoku (motorcycle and moped gangs in Japan) are well known for  their love of modifying their cars to make them appear lower, wider and more  impressive looking.

It is not known whether Morohoshi-san is  truly affiliated with the Yakuza, but he admits his business is in a ‘grey  area’.

Film-maker Mr Huxham adds of his new  acquaintance: ‘Style is personal, fun is universal.

‘That’s what you need to embrace before  watching this film. Morohoshi-san is living between  the lines, somewhere in  that grey section.

‘Mixing with the undesirables and modifying  his Lamborghini in ways most of us  would never dream of doing. His style is  unique and questionable but one things for sure, he’s too busy having fun to  care what you think.

Morohoshi- san’s ‘style is unique and questionable but  he’s too busy having fun to care what you think’ according to Mr  Huxham

‘And that’s truly what makes him a cool  character.’

Just last month police seized a  ‘glow-in-the-dark’ supercar from a London street after its wealthy  Qatari  owner was stopped for not having a licence or the correct  insurance.

The £350,000  Lamborghini Aventador – with a  paint job that made it look like  something out of the sci-fi film Tron – was  impounded near Harrod’s in  Knightsbridge.

It is  understood its owner is 24-year-old  Nasser Al-Thani, a member of Qatar’s ruling family. Police stopped the car on  Brompton Street and had it  towed away after Mr Al-Thani failed to produce a  licence or the correct  insurance.

Wealthy Middle-Eastern drivers descend on the  capital in their supercars every summer, and the Al-Thani family in particular  are renowned for their supercars. They hit the headlines  three years ago when  their blue Lamborghini and Koenigseggs were clamped outside Harrods.
