I'd suggest caution in using WP for this. WP tends to get a
lot of activity on current events (I usually don't bother editing them for that reason), this one is less likely to draw on the usual contentious/opinion driven contingent, but it is always a risk.
Quite a lot of "current event" incidents are badly covered on WP until some time after the fact.
Facts and figures could well be very wrong; with lengthy discussion on the talk page ironing it out. There is also a strong western bias in the writing/sources, especially (as it happens) with regards to Japan. Finally; people will tend to write their own interpretations and comment on such events; some of which hangs around longer than it should.
Use with care :)
