Where are all my single guys at?  Here is a topic for you to discuss all the tips and strategies you have tried, and failed with. 

Discuss the things that you have learned, and the things you have made mistakes saying or doing in a relationship with a Japanese Woman in Japan.

If you need advice on dating a Japanese women then you don't belong here...lol

Wow... way to call them easy. Good goin, dude.

Learn some Japanese. Takes time but increases the odds. You can actually download Japanese lessons on podcasts if you so choose. The GI Bill will pay for college language lessons. While you're learning watch Japanese TV; it comes complete with subtitles on evening programming so you can practice reading as well.

Learn the culture and ask them to teach you. Go on day trips. If you meet them in a bar don't try and pick them up. Make arrangements to meet them at some other time. Have your own personal business cards made with English on one side and Japanese on the other. Sometimes, though, it may be better to just make sure your keitai profile is up to speed and send IR to theirs...make sure your profile has a nice photo of your face only in it.

Stay tuned...I been doing this a long time!

and a "keitai profile" is what?
