Japanese banks after the crisis

I've just read that uncertainty has now hit the Japanese banking sector:

In the last 7 days Origami Bank has folded.

Sumo Bank has gone belly up.

Bonsai Bank announced plans to cut some of its branches.

Yesterday, it was announced that Karaoke Bank is up for sale and will likely go for a song,
while today shares in Kamikaze Bank were suspended after they nose-dived.

Samurai Bank is soldiering on following sharp cutbacks,

Ninja Bank is reported to have taken a hit, but they remain in the black.

Furthermore, 500 staff at Karate Bank got the chop and analysts report that there is something fishy going on at Sushi Bank where it is feared that staff may get a raw deal!
