"Akishio" took part in the Pacific Reach 2000 drills, which took place from 2 to 14 October 2000, off of Singapore. The navies of the United States, Japan, Singapore, and South Korea took part. Because of the Kursk submarine disaster which had happened earlier that year, the Pacific Reach 2000 drills involved submarine rescue exercises, which "Akishio" performed in. This was the first time Japanese ships had taken part in a multilateral submarine rescue drill, although they had taken part in similar exercises bilaterally, with the US Navy. Japan's constitution places limits on their ability to perform collective-defence drills. Because of this, Japan joined the drills from a humanitarian standpoint, rather than a military one.
