I went with my friend a while ago to the Hazard Prevention Safety Museum.
At the museum, which was actually free, I got to:
1) See a cool IMAX earthquake video complete with vibrating chairs.
2) Experience a large earthquake on a simulator. The whole room was on hydraulics and shook violently.
3) Go though a smoke filled maze. There were locked doors, zero light, and I had to stay low to the ground to avoid the smoke above.
4) Learn CPR, and practice it on a dummy.
5) Finally be able to use a fire extinguisher to put out a fire on a large screen.
6) Practice calling the emergency number, which in Japan is ‘119′.
