There are certain bars and such where you can get Japanese girls easily even if you don't speak Japanese at all. Those are the places where the "gaijin hunters" go to find a cool foreigners to have sex and learn English with. BUT. In my opinion, the level of those girls isn't that high. And they always seem a little crazy or something. I don't know. By learning Japanese you can start a conversation with anyone. If you're good looking you can easily give it a go with those Tokyo Drift kinda girls and even if you're just a normal guy you can find pretty awesome girls because there's a lot of Japanese girls who are genuinely interested in foreigners but they don't have what it takes to communicate in English. And it's really common to want to date a foreigner. Also, nowadays "halfs" - half-Japanese and half-foreigner - people are considered really attractive so there's even a lot of girls who want to have your babies.
No, there are a lot of Japanese tourist come to Bali every year (summer is the perfect time) my friend now has a japanese girlfriend, and it's no wonder if a native tour guide could marry a japanese girl, come to Bali, use your English and a basic Japanese, ypu'll get Japanese girl here![]()
Your average Japanese woman isn't like the women in JAV. Sure, the ones you pick up at bars who are late 20s will screw your brains out but you don't want them as a wife. In fact if you do even a little research online you'll see that Japanese women in general are having less sex and less interest in it.
You're never going to pick up a girl in Akihabara unless they're a prostitute.
I've never visited a prostitute in Japan, but my understanding is they only accept Japanese clients (if they're any decent anyways). I would assume they do kissing though...
And yes, I've got Japanese woman, together 4 years this year and she's as every bit gorgeous as any JAV model (but much more timid).
