FWIW, one of the most commonly believed things about Japan (domestically and internationally) that I believe is dangerously false is some variant of "Japan is not good at coming up with original ideas. It is good at perfecting ideas made elsewhere." There exist fields/time periods/etc where Japan has clear sustained leadership in innovation, just as there exist fields/time periods/etc where the same is true of the US.
"CRUD web applications between 2004 and 2014" has not been a particularly great example of Japanese technology leadership. Videogames in the 80s/90s/2000s or "Every mobile music device prior to the iPod" or "Robots, 1970 through present, excluding drones 2010-2014" or "Cell phones considered as hardware artifacts, prior to the iPhone turning them into software platforms" are all good examples.
