See it's dated December 2011.

March 2011 is when Japan had it's largest earthquake, a 9.1.

The Japanese seem to take disasters more seriously since then. Wasn't there a link on here to the kit breakdown every household is expected to have. Which included things like safety helmets etc.

And they have a facility to train people on what to do in a quake/typhoon/fire.
