Japan's five-year-long operation to aid in the reconstruction of Iraq came to a formal conclusion Sunday with a ceremony commemorating the return of personnel from Kuwait to the Air Self-Defense Force base in Aichi Prefecture.

The personnel had been carrying out tasks related to Japan's withdrawal since early December at a Kuwaiti base.

The ASDF used the Kuwait base to airlift goods and personnel for multinational forces and the U.N. to and from Iraq.
