Defense Agency Director-General Fukushiro Nukaga arrived in Moscow late Thursday as part of a 10-day visit to Britain, Russia and the United States focusing on Tokyo's timetable for withdrawing from Iraq and relocation of US troops in Japan.
"Defense chiefs will discuss the existing and potential military cooperation between Russia and Japan, including joint exercises of the navy, air force and land troops or rescue operations," the source said, adding that "technical cooperation is not on the agenda."
Russian Defense Minister Sergei Ivanov and Nukaga "will also exchange views on international and regional security issues. That includes comparing notes... on Iraq, Iran, Afghanistan and North Korea's problems," the source said.
Nukaga is due to leave Russia on Saturday.
