>less local/more federal legal zoning and land use power, more federal level direction to get things done,
Nitpick: this part isn't correct. There's no federal legal zoning or direction or anything federal at all. Japan doesn't have a federal government; like most countries, it has a unitary government. The US is unusual this way, along with Germany and Russia.
But otherwise, you're right. It's much easier to build stuff here for all those reasons.
That's a great blog post. As I understand it, the national law is just as described, with only 12 zones, but the localities have some latitude in how to apply the law and make some blanket restrictions about things like building height. For instance, Kyoto famously has very strict limits on building height, though this is biting them in the ass because it keeps them from creating enough density to get more tax money, and too much land is occupied by religious sites that don't pay any taxes at all, so the city is going bankrupt.
