Prosecutors will question fired Japanese diplomat Kazuhiko Togo over an allegation that he broke rules regarding travel expenses.

Togo allegedly ordered a government-funded committee on Russia to pay the travel expenses of Japanese who went to Israel in 2000 to attend a conference, investigative sources said Sunday.

Togo, former ambassador to the Netherlands, was dismissed April 26 for his shady ties to scandal-hit lawmaker Muneo Suzuki. He apparently forced the panel to foot an approximately 30 million yen bill, even though such payments are against the ministry's rules, the sources said.
