I thought that Japan didn't use 72 MHz, but upon looking it up, it
appears they do --

However, they seem to have a lot fewer 72 MHz channels, which makes me
wonder what the size of them are. If they're 10 KHz like in the US,
and if the channels match (they appear to) then you ought to be good
-- it may not be technically legal, but it would at least be safe, but
if they're bigger than 10 KHz then you may interfere with other
things (and they'll interfere with you.)
I'd suggest calling/emailing JR. Write down all the numbers and marks
on the module and they should be able to tell where it's legal to use
it.
At worst, you'll have to replace your module, which will cost under
$100 (just under $100 for a synthesized one) or send it into JR.
