Been here in Tokyo three days now and I haven't seen a single Z! Ferraris, Porsches, Bentleys, a GTR, a couple of Lambos, an Aston.... but not a single Z of any age!
Also...
Apparently they don't keep cars very long because their version of an MOT is every other year and costs about $1000!
And if you want to buy a car, you have to prove to the police you have somewhere to park it before you can buy it.
Been round most of the famous tourist spots in Tokyo - next up is Mt Fuji, Hakone, Kyoto then Hiroshima.
