Some stuff has worked pretty well. I registered for a MyNumber card after years of dragging my feet. Now I can check how much tax I've paid, how much I have in my retirement fund, health insurance things, and a bunch of other stuff from my phone in like 10 seconds all from a single app. Previously I'd need to take a half day off, bring my wooden stamp to the appropriate government office, and wait for 10-30 minutes in order to make sure my stuff is in order.
I'm actually amazed how well it works.
Japan also builds infrastructure really fast.
It's not perfect, and some things lag behind other countries, but some things blow some other countries out of the water. If anything, I'd say the government moves pretty quickly with a lot of decisions (one consequence of being what's effectively a one party state, I suppose). Companies, particularly big ones, are more risk-averse.
