I don't know how they handle infrastructure, but whatever they do seems like something the rest of the world could learn from. A little while ago it made international news when they fixed a sink hole in a few days: http://edition.cnn.com/2016/11/15/asia/fukuoka-sinkhole-fill...
It should be noted that that sinkhole re-occurred shortly afterwards.

Th original sinkhole was caused by a collapse of a under construction subway tunnel. This second time is just regular settling, there was no second collapse.
There is also this:
1,200 Japanese workers convert above-ground train to subway line in a matter of hours.
