Here's some advice for you and can be applied to any culture in the japanese...
Pick a nice restaurant. Ask a few questions beforehand and find out what types of foods she likes. You may assume that Japanese women like Japanese foods - true, but many Japanese young folk love to try out different cuisines, like French and other European cooking. Japanese girls love clean, light, aesthetic dishes, so you need to get more info related to her before you lock onto which restaurant you want to take her to.
Spent some money to dress yourself up. Most Japanese women like to dress up and groom themselves a particular way. In the same way, they will expect their date to also dress up properly - respect can beget nookie.
Act like a gentleman. Something like opening car door; moving the seat out for her at a table; hold a door open anywhere... treating her well shows you really care about her. Not only for Japanese women, though - but for all women.... and for god's sake hold a door open for everybody!
Take your time. Japanese women do not like to rush into anything physical. Don’t pressure her, especially on the first date. Do not make your first date a rush, as Japanese women do not like to be rushed - or any woman for that matter. Did I repeat myself? I tend to rush when I write.
Understand the cultural heritage of Japan. You can try to ask some questions about her family and how she grew up and what her happiest childhood memory is. Despite the over-worked father who is never around, the amount of school work and the harried mother, the family unit is extremely important to Japanese society.
Communication can always be a problem when dating Japanese women, but it can be overcome. Teach her new phrases and words in your language - and she'll do the same for you. Ask her what she knows about knows about your country and how she feels about it. In this way, you can teach her more about you and your culture.
So... have you noticed a pattern here on how to date Japanese women? Yes... aside from learning a bit about the language and social customs... you should learn about the likes and dislikes of her and take the lead when it comes to arranging where and when to date. And then treat her with respect. All pretty simple and basic stuff.
To be honest, if you aren't doing this stuff already in Japan or whatever country you are in, you aren't dating a woman very well.
You want my advice on how to get a real Japanese woman - or any woman for that matter? Take an interest in her. Much like when you are buying a car or a new television, you do some research. It's called asking questions and taking an interest.
