17 August 2012, the Japanese Financial Services Agency (FSA) ordered an investigation into TIBOR, or Tokyo Inter-Bank Offered Rate.

It’s a system similar to Britain’s LIBOR, and tries to regulate interest and currency rates.

18 financial institutions in Japan have been ordered to reveal their TIBOR operations. Specifically the FSA is looking for evidence that bank employees unfairly manipulated rates.  FSA is concerned about the credibility of the TIBOR system.

The Japanese Bankers Association gave an immediate response to the order, saying their were no TIBOR irregularities, despite the European and U.S. investigations into TIBOR.
