Howdy. I have a few connections in Japan, as well as go there quite often and am often able to find many parts there to ship to the US. The shipping usually isn't that cheap, but if you're in need of a part - I can try and help source it. Hoping to open up a parts section on my website eventually. Feel free to reach out and shoot me a PM if you may be in need of something and I'll see if I can help. This also goes for those of you with JDM vans in particular, like the Townace, Liteace, Hiace, etc.
Cheers
