Meet the maddest Lambo tuner...

There are three types of people here - irredeemably drunk salarymen limping into skin bars, self-conscious lost boys distressed to rebellious perfection, and groups of men moving with slow, cinematic confidence. Their suits are perfect, and they're the ones to worry about. Yakuza, Japan's Mafia - the largest organised crime syndicate in the world. Revered as folk heroes, like modern-day samurai, they hide behind a paper screen of Western sophistication. Related by blood: theirs or other people's.

Today, there's a fourth. There's only one of him, and he's called Shinichi Morohoshi. His shoes are disco balls. His hair is electric. His jewellery hurts to look at. He's dressed in Tokyo's psychosis, like the ultimate aspiration of the light show that defines this city. Despite his open ties with Yakuza, he's playful and disarming.
