I’ve contacts in Japan - my wife’s first cousin lives there and her husband is Japanese (as are her kids - half Peruvian).

Yes judging by the forums and also eBay it’s much bigger. Which leads me to wonder why the old skool BMX forum on retrobike is very quiet compared to road and MTB.
I wonder whether a one off BMX of the month might spice it up a bit?
