Democratic Party of Japan leader Ichiro Ozawa decided to remain in his post after his chief secretary was indicted Tuesday on a charge of violating the Political Funds Control Law. The party endorsed his decision.

Mr. Ozawa said the content of the indictment proved that he himself was not involved in bribery or other crimes. He also said he will do his best to have parliamentary democracy take root in Japan by wresting power from the Liberal Democratic Party and Komeito in the coming Lower House election.

The decision by Mr. Ozawa and the DPJ shows they expect little damage to the DPJ, as they're counting on people to understand Mr. Ozawa's explanation. But there is no guarantee that people will. Unless Mr. Ozawa and the DPJ clearly detail their interpretation of the requirements under the Political Funds Control Law, it will be difficult to regain people's full trust.
