It's getting approx 15-20 uniques per month the last couple of months - not a lot, I know, but shows an increase from virtually zero 5+ months ago. Along with some other .jp names I've got, traffic is slowly building up. Along with that, the 'keyword gravity' (ref FS) of the name is obvious.
If you're looking for current traffic, I've got to be honest and say this isn't for you. If you are looking to take a punt on a potentially great name based on keyword quality, then maybe it is...
