A week after the 9.0 quake, computer system problems continue for Japanese banks.

Mizuho Bank is unable to process salary payments for more than half a million people.

Also, Internet banking and ATMs would be offline over Japan’s upcoming three-day weekend.

On Thursday, Mizuho bank’s nationwide ATM network of more than 5,600 machines went offline until midday, then failed again in the evening, and more  problems on Friday.

Like I said before, another good reason to keep your money under the mattress (unless you think it’ll float away in the flood).
