I've been in Japan nearly four years, and never knew what to say about dating in Japan- or rather, I wanted to research more and give correct information, as it kept changing through the years.
I explained that there are some of us who fancy them, too. On the arguing point; what tends to happen with me and the partner is that so many potential confrontations kind of get brushed aside, or stored away somewhere usually labelled at as 'well, we're front opposite ends of the world'.
Then I think the storage space reaches over capacity and we end up have a proper argument in which she speaks really quickly in Japanese, and I can't quite keep up with what the problem is.
At some points I found it really fun and easy, then found it extremely difficult, and now, I'm in a stable place.
On one of my first nights in Japan, while training in Nagoya, my friend Mike and I went to a small foreigner-owned bar where we met a Black Francis look-alike (if you need to google this, you seriously need to pick up a few Pixies albums).
I never went running back to Black Francis, but while not being entirely wrong, the guy had a point.
Foreign girls dating in Japan don't always have it easy, but I think many of them make it difficult for themselves.
The advice here is to take initiative and surprise the girl with your boldness and courage.
Whether you confess in English or Japanese is up to you, from my experience and knowledge it does not really make a difference.
For several months and perhaps years following that encounter, I laughed at how ridiculous his words were, and wanted to prove him wrong- which I did for a while.
Then, as I found myself more single than ever, I started to think he maybe had a point.
