Yamada is suspected of giving the money to the Japan-U.S. Center for Peace and Cultural Exchange to secure subcontracting work for a project to remove leftover poison gas shells from Fukuoka Prefecture.

The Tokyo District Public Prosecutor's Office will file additional bribery indictments against former Vice Defense Minister Takemasa Moriya, 63, and former Yamada executive Motonobu Miyazaki, 69, alleging that Moriya received about ¥3.6 million in cash from Miyazaki in return for favoring Yamada in equipment contracts when he was the top defense bureaucrat.
