RE: My guess is that somebody in the Japanese government has rightly become aware of the problem of Muslim immigration and infestation.
http://en.wikipedia.org/wiki/Islam_in_Japan
in 2000 Keiko Sakurai had estimated the number of ethnic Japanese Muslims in Japan at 63,552, and around 70,000 - 100,000 foreign Muslims residing in the country.
So, at 200,000 Muslims, that’s 0.16% of the population.
To me. Any statistically significant measure of Muslim population in a country, i.e., anything numbering in the 100 of thousands is a real problem. For most countries, approaching 1-2% of the population is a sign of dire degradation.
Believe it or not, I don’t care. It is a pestilence and it only takes one seed.
