Most of that shit either didn't exist when cyberpunk started or was completely different from what it is now
As for why japan, simple: it was the highest high-tech place on earth in the 80s
Most japanese cities got bombed/burned to the ground during WWII, most buildings were made of wood so there was even less stuff left than in germany, so most buildings were much newer than in other major cities
To that add the economic miracle that made some people believe japan was going to become the #1 economic superpower
