Do Japan have any protection plans for future earthquakes?

Question:

What is being done in Japan to plan for and prepare their population for earthquakes? Do they have any systems already in place? Do they have any sort of drills for when earthquakes occur?

Again.. Just curious.

Answer:

There is a huge amount of planning done for these kind of things - building specifications are very high, hills and slopes get reinforced, there are tsunami sea walls and early warning systems (which generally work well, but defenses which were thought to be sufficient were not in this case). Within 1 minute of the quake starting emergency systems were already swinging into place, the nuclear plants were shutting down (if only the backup systems had been better in Fukushima we might not be having such severe problems now), bullet trains wouls have been stopping, the whole infrastructure here is fantastic. Sadly, when confronted by a 10 - 15 metre tsunami caused by one of the world's biggest earthquakes, all the planning in the world can only do so much. At lease there will be considerable retrofitting of safety measures in all power plants now.
