Thank you. That's informative. Perhaps it's the Japanese government who is facilitating this theft for the benefit of its citizens. If so, they are killing a golden goose.

I have decided to stop wasting time here, and let you all feed the panic instead.  It is much more profitable.  I managed more than 18% on my last round of arbitrage, all fees included.  I wonder if I'll be able to get 25% on the next.  

Please keep panicing!  Never search for the true answers; make up your own!  Don't ever believe it is possible to withdraw anything!  Don't believe arbitrage is possible.  Please keep spreading rumours that MtGox are broke, etc.  I've never made this much money with no risk and almost no work!  I'm in my last week of full time employment.  From now on I will make a living out of the price difference between Panicstamp and MtGox, and my bot of course.  You guys!  I love you all for making this possible!

For all the other arbitragers who are making good money on spreading FUD here: I think you are a bit dishonest, and there is no need to.  The clueless people here are fully capable of creating a panic for themselves.

OK, I can't resist revealing some information about JPY withdrawals.  Last known processed is from January 5th.  Reason for the delay is 9 days of closed banks (Mizuho) and this:
The daily limit is 100 million JPY, btw.

For everything else there is not much new.  You will find the answers on previous pages in this thread.
