Following problems in the sub-prime lending market in the US, uncertainty has now hit 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 for sale and will likely go for a song, while today shares in Kamikaze Bank were suspended after they nose-dived. Furthermore, 500 staff at Karate Bank have got the chop and analysts report that there is something fishy is going on at Sushi Bank, where staff fear they may get a raw deal.
