The Bank of Japan punished 98 officials April 10, including two executive directors, for their connections to the bribery scandal hanging over the central bank as well as other questionable conduct involving financial institutions.

In addition, Gov. Masaru Hayami and six other senior executives voluntarily surrendered 20 percent of their monthly salaries to show the central bank's determination to start anew, it said.

The concluding announcement caps three months of embarrassing revelations about the central bank, and also indicated that accepting free dinners has been common among BOJ officials for many years.
