A spoof financial news story has been doing the rounds - a sense of humour is probably all many bankers have left

Following the financial crisis on Wall Street uncertainty has now hit the banking sector in Japan.

In the last seven days Origami Bank has folded, Sumo Bank has gone belly up and 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.

While Samurai Bank is soldiering on following sharp cutbacks, Ninja Bank is reported to have taken a hit, but they remain in the black.

A spokesman for Haiku Holdings was lost for words over the financial crisis, while according to rumours Nippon Bank was starting to feel the pinch.

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 staff may get a raw deal.

Meanwhile Geisha Bank has bowed to the inevitable and shut.

One trader lamented: "It's all gone to Shiitake."
