Japanese girls can make more money in Japan than in Canada. Also, not many Japanese people in Toronto, so not much to draw from inside the country and not much of a reason for the average J-girl to relocate to Toronto. You would find more J-girls in Vancouver but even there, J-girls are out numbered by C-girls. And in Japan, the brothels won't let you see the girls because you are not Japanese. Japanese people are SUPER racist.
Join a dating website that matches J-girls with guys from around the world. Very easy to get a J-girlfriend. Visit her in Japan, fuck her 20 times by staying at her place (free of charge) and tour Japan while you are there. That's your best bet.
Google Ai Shinozaki. You might like her.
Or, when all else fails, just ask Krayjee. That guy is better than Google when it comes to hookers.
