Opposition lawmakers on Wednesday revealed what they claim is a letter and an internal memo from a Resona group whistle-blower suggesting that the Financial Services Agency pressured Resona to window-dress its capital adequacy ratio to prevent its insolvency from surfacing.

The Democratic Party of Japan demanded during a Diet committee that Financial Services Minister Heizo Takenaka question FSA officials who are suspected of involvement in the matter to confirm whether the allegations are true.

Although Takenaka told the House of Representatives Committee on Financial Affairs that he conducted hearings of officials and confirmed that the agency did not apply such pressure, he agreed hold hearings again and promised to report the results to the Diet.
