Finding gainful employment in Japan after leaving the US military?

When I leave the military (I've been here in Japan for a while), I'd like to stay in Japan and work for a Japanese company. I have a degree in networking (but no job experience) and extensive experience with project management and planning, Japanese business culture, Japanese governmental affairs, investigative work, and I was told by a high-ranking Japanese officer that he would give me a letter of recommendation when I transition to civilian life (no idea how much weight that will have). I speak Japanese and have some time left to continue to improve it. I was considering attending the Boston Career Forum about a year before I get out to see what the job market is like, but I was wondering if anyone can shed some light on what I'm up against. I will be just shy of 30, which I understand is rather old. I suppose I'm concerned with whether or not a Japanese company will consider my miltiary experience, especially considering most of it was spent working alongside the Self Defense Force, applicable or if they will basically consider me just another inexperienced gaijin that learned Japanese. I'm aware that this is very subjective, but I would love to hear some other experiences. I want to avoid working on a US base when I get out for obvious reasons, but I'll be damned if I can't stay here.

Thanks everyone!
