It is said infrastructure of Japan is high level in the world. I don't aware how high level of that, because I had lived in there since I was born. The most conspicuous example is we can drink tap water any park and any buildings. Once we go out japan, they would know easily that difference of quolity.
Now I live in India, I feel inconvenience that country's infrastructure. In tokyo, there are 900 station. Tokyo of popuration is 13milion so how many rairoad is spread with compared mumbai you can image easily. If we walk 10 minutes in downtown, we can find other station.
We have 44 prefecture, all of that have airport and bullet train is passing which can run 300km per hour, that is the fastest vehicle on the ground in the world. besides the load for car is like network on the map. All most of that is neatly mentenanced. In mumbai people always have a problem of traffic jam, because they have only a couple of higway and line of train.
Besides describe about network, we can use Internet anywhere for 24 hours .Internet line in almost of building is passing. Not only the Internet, water and electricity, gas, phone network is supplied always. If these is stoped even for a moment, mas meddia would pick up this incident immediately.
Japan helps to make infrastracture for korean and China and Taiwan other countries. They have a high quality technology of infrastracture in Asia.
