The phrase “Japan has been living in the future since the future since the 80s” comes to mind. For a country so deeply rooted in the technological revolution of the last 50 years, it certainly doesn’t feel like it when your there. It’s a weird mix of culture, history, and a deeply capable people hamstrung by economic forces.
I think a lot of things stick around because they have a good bespoke manufactoring industry and maintenance practices. Old infrastructure and automations that were built during the bubble era still work and you can still get parts made for them.
Even great Japanese corporations like Nintendo and Sony make it a lot harder for them to take my money than, say, Steam and Amazon.
