Uncertainty has hit the Japanese banking industry.

In the past week, Origami Bank has folded, Sumo Bank has gone belly up and Bonsai Bank announced plans to cut some of its branches.

Last week, it was announced that Karaoke Bank is up for sale and will likely go for a song, while shares in Kamikaze Bank were suspended today after they nosedived.

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

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