In Tokyo Bay, fast-moving Japan Coast Guard vessels confront a suspicious vessel and fire warning shots to bring it to bay.

Coast guard members then board the vessel and detain the "suspects."

Thousands of onlookers applauded the quick takedown in an anti-terrorism demonstration on May 19.

It was part of the first JCG fleet review in six years.

Along with the JCG’s patrol boats and helicopters, vessels from police and fire departments, and the U.S. Coast Guard joined a parade in Tokyo Bay.

A total of 37 ships and 15 airplanes participated. Along with fighting terrorists, life-saving rescue demonstrations were also staged.

About 3,000 people, including those who came through a public invitation, were on hand to review the fleet.

The review of the fleet had been held annually around May. In recent years, however, it has been suspended as the JCG was busy dealing with intrusions of Chinese government ships into Japanese territorial waters around the Senkaku Islands in the East China Sea.

The review was restarted this year, which marks the 70th anniversary of the establishment of the JCG. In addition, the JCG's system to monitor sea areas around the Senkaku Islands, which are also claimed by China, has been strengthened.
