@ veiled ladies
Have quite a few in Sapporo. Most are either University Grad students or wives of University Grad students.

@ immigration
Immigrating is probably easier than the US but takes more time.

@asylum
Japan is having enough trouble dealing with it's gaijin population let alone accepting people off boats. Japan patrols it's shorelines pretty heavily and has news on every once in the while about 10 Chinese escapees flooding the town.

Sorry, it just seem that the Chinese are the ones always on TV.

Several years ago 18 Chinese came over in a container. 8 dead and 10 were deported ASAP. Big news back then.
