TOKYO- A former school principal who allegedly paid for sex with 12,000 women while in the Philippines was arrested in Japan, media reported today.

According to sources, Yuhei Takashima had meticulously catalogued nearly 150,000 photographs of his exploits over a 27-year period in around 400 separate albums.

Takashima, 64, told police he started paying for sex when he was dispatched to a Japanese school in Manila in 1988. Thereafter, the former middle-school principal had been on three sex tours a year to the country, for a total of 65 visits, reports said.

During this time, he had sex with more than 12,000 women, aged between 14 and 70. He was arrested for having sex with a girl in Manila last year believed to be 13 or 14.
