OUR hero could somehow be involved in tourist scams

The yakuza's tentacles reach into many different areas, principally corporate extortion, gambling, smuggling, loan sharking, money laundering, narcotics, real-estate, sports, entertainment, stock manipulation, tourist scams, sex tours, prostitution, slavery, pornography, and gun running.

Sex-related enterprises are the yakuza's bread and butter, and they cater to the wild side of Japan's overworked, buttoned-down "salary men." The yakuza smuggle truckloads of pornographic films and magazines into Japan from Europe and America. They control prostitution rings throughout the country, commonly holding young women from other Asian countries captive as indentured servants and forcing them to work as "comfort workers." The Japanese euphemistically refer to the act of prostitution as "selling spring," and Japanese johns have a taste for very young women, as demonstrated by the national obsession with young women in school-girl outfits complete with short pleated skirts and knee socks. The yakuza buy unwanted female children from China--where the law restricts couples to only one child and the cultural preference is for boys--for as little as $5,000 and put them to work in the mizu shobai (literally the "water business"), the yakuza's network of bars, restaurants and nightclubs.
