Ask HN: What does the possible meltdown mean for people living in Tokyo?

I know a lot of cats on HN are pretty educated on a whole range of topics. I live in Tokyo, and have come to realize I know next to nothing about how this could play out. Throwing it out there for anyone that has the education to answer and has been following the latest reports.

Also a shoutout to http://twitter.com/timeouttokyo/ for doing an amazing job keeping everyone in the know as stories develop.
