I also have japanese unit, and I can assure you, that region of EBOOTs taken for making PSAR for flashing, has no meaning. I sometimes use US, sometime JP, or even mix (1.50 EU and for example 3.52 US). It's not important, because keayassign is not in the update, but in registry (my guess).

In acient times, when i get my japanese unit with 1.52 OFW, I updated it with US 2.00 EBOOT, and then downed (tiff exploit) with EU 1.50 eboot. The keyassign was alwas the same (O - enter). As brun0 said: u can always use registry hacks build in CF to set key you dissire, and to set region for japan.
