The report on the data leaks at the Japan Pension Service (JPS), released Thursday by its internal body, has revealed that a culture where no one takes responsibility existed in the Social Insurance Agency, the JPS's predecessor, and continued at the refurbished entity.

Prime Minister Shinzo Abe's administration apparently wants to put an end to the incident by showing that the government is taking measures to reform JPS, but it is unclear whether they will actually be realized.

"At the bottom of the incident, there are various problems that have been pointed out since the time of the Social Insurance Agency," said the report, explaining why JPS couldn't prevent the information leak.
