Japanese young women often have little time, and furthermore, social control works more tightly in Japan than in practically every other Asian country, except Brunei and, maybe, Malaysia, though it is very different in Japan in that it is based on peer pressure rather than control by authorities.

Japanese girls and young women, when they are beautiful, are also heavily courted by young and not so young Japanese men.

Furthermore, foreigners have a hard time establishing a foothold in Japan. Rents are expensive, and many landlords do not want foreigners as tenants.

For all the above reasons, and possibly some more, your best bet for picking up a Japanese girlfriend may well be not Japan, but ... Bali in Indonesia.

Bali is a favorite holiday destination for Japanese tourists, including Japanese girls, who usually travel in pairs.

There are numerous advantages to targeting Japanese girls outside Japan, at holiday destinations such as Bali.

The most important is that they then have time. Because they typically travel with their best friend (with whom they share all secrets), there is practically no social control of their behavior.

And anyway, many Japanese girls do travel with an idea of having a sexual relationship during their vacations.
