Sporting a pinstripe suit, a wiry figure hovers on the main street of Shinjuku Ward's Kabukicho -- Tokyo's busiest and arguably seediest entertainment district.

Every night for 14 years, Lee Xiaomu has approached foreign visitors roaming the neon-glittering streets and offered to escort them to bars, restaurants, strip shows, night clubs, porn shops -- whatever tickles their fancy.

"I am a Kabukicho guide," said Lee, distinguishing himself from regular hawkers in the area.
