Happy days mate ! You get a few extra goodies with jdm usually the only other things to check are that the jap de reg certificates are all present and correct, if it's been under sealed properly, the arches are not rusty, & if your lucky it's already been remapped for uk fuel,
there's a site you can check the odometer readings at the time of export, I forget the name though.
