Internal affairs minister Minoru Terada on Monday acknowledged that a political funds documentation scandal that has engulfed him involves a breach of the law, although no punishment can be handed out.
Terada also apologized for incorrectly telling a parliamentary committee that the documentation error could have resulted in charges being brought against someone linked to one of his support groups.
The issue has increased pressure on Prime Minister Fumio Kishida, who has been hit with a string of issues, dealing a blow to his Cabinet's polling numbers.
