NHK did a brief report on the tsunami alert announcer who was killed in the line of action (Miki Endo) and can be viewed here: http://www.youtube.com/watch?v=i6Kl08zHiJY&feature=related

Al Jazeera produced a documentary that described how one school was able to save most of its children by subscribing to a Japanese tradition called "Tendenko". Essentially, it teaches that after a tsunami, you must evacuate yourself to higher ground without regard for your loved ones or others. (The fear being that trying to locate others will get you killed). It is a fairly long documentary but is pretty remarkable. It is a stark comparison to many civil preparedness training programs where it is encouraged to "check on your neighbors".
The documentary can be seen here:
