Japan may bar Julien Blanc, who teaches how to aggressively pick up women

Julien Blanc has had his seminars on picking up women cancelled by venues in the US and Australia - which then added to his humiliation by deporting him - and has been informed that he is not welcome in Canada, Britain and Brazil.

But will he show up in Japan to demonstrate his aggressive and abusive techniques to men who pay to learn and mimic them?

Blanc, 25, is scheduled to deliver a seminar today at a secret location in Tokyo. Yet he may have thought better of it, given the worldwide condemnation that his pick-up tactics have attracted since Chinese-American blogger Jennifer Li first saw a video of Blanc in action on the internet.

What started out as a one-woman campaign to expose Blanc's approach to women swiftly won support around the world. And with Tokyo the next place on his list for classes, anger is building.

"I went to the immigration office with a group of people this week to deliver a petition protesting against Blanc's plans to come to Japan," Jake Adelstein, author and operator of the Japan Subculture Research Centre website, told the South China Morning Post. His petition has about 36,000 signatures, according to reports.

"The authorities there gave us the on-the-record comment that went along the lines that they were happy to receive the information, that they would examine it carefully and then make the proper decision in accordance with the relevant laws - but I got the impression that they didn't want to let the guy into the country either," he said.
