The knock on from the US sub-prime market in Japan shows no signs of letting up.

In the last 7 days Origami Bank has folded, Sumo Bank has gone belly up and Bonsai Bank plans to cut back some of its branches.

Yesterday it was announced that Karaoke Bank is up for sale and more than likel y will go for a song. Today shares in Kamikaze Bank were suspended after they nose-dived and 500 back-office staff at Karate Bank also got the chop.

Analysts report that there is something fishy going on at Sushi bank and staff fear they may get a raw deal.
