TOKYO - Japanese Prime Minister Yoshihiko Noda emphasized the importance of Japan's Self-Defense Force on Sunday during his fleets inspection, saying that the role of SDF is increasing following emerging territory issues.

"Various developments over territory and sovereignty have been arising," Noda said in Sagami Bay off Kanagawa Prefecture on the Maritime Self-Defense Force (MSDF) escort ship Kurama. "In the new era, the roles of the SDF have become increasingly important," local media reported.

Forty-five vessels participated in the event including ships from the United States, Australia and Singapore navies. It was the first participation of foreign ships in the MSDF fleet review since 2002, media reported.
