An Imperial Japanese Army veteran planning to speak overseas about Japan's wartime atrocities in Asia left for Canada on Thursday, despite a warning he would be denied entry, according to his trip organizer.

Yoshio Shinozuka, a former member of biological warfare unit 731, left Narita airport Thursday afternoon for Toronto, said Kohken Tsuchiya, a lawyer and leader of the group organizing the tour.

The Canadian Embassy informed Shinozuka on Tuesday that he is banned from the country due to his involvement in crimes against humanity during World War II.
