8. Japan Coast Guard
The Japan Coast Guard (*1) made both waves and headlines in 2001 when its patrol boats exchanged fire with a North Korean spy ship, a duel that eventually ended with the sinking of the rogue vessel. The incident shed light on the Japan Coast Guard, an affiliate of the Ministry of Land, Infrastructure and Transport.
In a word, the duty of the coast guard is to maintain the safety of Japanese waters including 200-nautical mile (370km) exclusive economic zones (EEZ). This involves a wide variety of activities pertaining to natural disasters, oil spills, illegal dumping, stowaways and drug trafficking, as well as lighthouse maintenance, ship salvaging and compiling tide tables. Japan set up EEZ in 1996, following the ratification of the United Nations Convention on the Law of the Sea.
One of the tasks that have gained importance lately is patrol of the nation's territorial waters. Coast guard vessels are constantly on the lookout for suspicious vessels suspected of involvement in illegal activities such as drug or weapons smuggling, human trafficking, or fish poaching. If a vessel is acting suspiciously, the coast guard can order it to halt for an inspection, which entails coast guard officials boarding the ship and checking for contraband or stowaways. Coast guard officials, who are often referred to as the policemen of the sea, are authorized to make arrests but until recently have not been permitted to use firearms except in self-defense.
As crimes on the high seas continue to increase, the coast guard has been expanding its fleet, making it one of the largest in the world, matching its US counterpart. As of April 2003, the agency had a total of 519 patrol vessels including special guard and rescue boats, and 75 airplanes.(*2) The coast guard has a special force unit trained in anti-terrorism and weapons use.
The law governing the coast guard was revised in November 2001 to give it more power, including permission for patrol boats to fire on suspicious vessels in Japanese waters to prevent them from escaping.
