The JCG has divided the nation into eleven regions to facilitate its coast guard operations. Each region maintains a Regional Coast Guard Headquarters, under which there are various Coast Guard Offices, Coast Guard Stations, Air Stations, Hydrographic Observatory, and Traffic Advisory Service Centers.

Special unitsEdit

The JCG maintains three national-level elite units for each specialized fields:

Special Rescue Team (SRT) (特殊救難隊, Tokushu-kyūnan-tai).
Rescue swimmers and public safety diving team. Regional counterparts are Kidō-kyūnan-shi (機動救難士).[3]
National Strike Team (NST) (機動防除隊, Kidō-bōjo-tai)
Offshore oil spill and chemical hazard response team. The Japanese counterpart of the National Strike Force (NSF) of the USCG.[3]
Special Security Team (SST) (特殊警備隊, Tokushu-keibi-tai)
Counter-terrorism tactical team. Regional counterparts are Tokubetsu-keibi-tai (特別警備隊).[3]

EquipmentEdit

VesselsEdit

Immediately after its creation, the MSA operated the second-hand ships of the former Japanese Navy, but it was only allowed to use smaller and slower vessels.[4] The designations of PL, PM, PS and PC were used to classify ships as being: Patrol Ship – Large, Medium, Small and "Craft" = very small. From FY1949 the construction of new ships began. Because GHQ instructed the service to model its ships after those of the USCG, the 700-ton PL Daiou-class was based on Cactus-class buoy tenders, the 450-ton PM Awaji-class patrol vessel was based on Thetis-class patrol boats, the 270-ton PS Kuma-class patrol vessel was based on Active-class patrol boats, and the 23-meter PC Hatsunami-class patrol craft used a USCG 75-foot patrol boat as a model. However, these copies of American ship types were found wanting as they neither suited the actual operational work of the MSA nor the sea conditions around Japan.[5]

As a result, when the Treaty of San Francisco came into force, MSA's own patrol ship's design work began. The PL type patrol vessels increased in size to the 900-ton Nojima-class patrol vessel, PS type patrol vessels differentiated into the 350-ton PS Tokachi-class patrol vessel and the 130-ton PS Hidaka-class patrol vessel. Later, the 350-ton class PS's were reclassified as PM type.[6]

In the late 1970s, it was clear that the new international rules on national exclusive economic zones would demand a considerable increase in the size of the Maritime Safety Agency fleets. To cope with this dramatic increase in workload, the 1,000-ton PL Shiretoko-class patrol vessels, 500-ton PM Teshio-class patrol vessels and 30-meter PC Murakumo-class patrol craft were built in large quantities. In addition, the Japan MSA also began protecting shipping operations by deploying air-sea rescue helicopters on-board PLHs.[7]

Since the 1980s, criminal ships had advanced into Japan's ocean spaces and were showing high speeds, also North Korean armed trawlers began to appear. For this reason, the MSA designed and built the 180-ton PS Mihashi-class patrol vessels that combined both ocean-going capability and high-speed performance. In addition, upping the speed of PL and PM type patrol vessels became important and this has also been achieved. As a final measure, by equipping JCG ships with remote control turrets incorporating automatic tracking functions applied to the ship's machine cannon, precise shooting became possible.[8]

StatisticsEdit

The JCG operates 455 watercraft, these include the following:

  • Patrol vessels: 121
  • Patrol craft: 234
  • Special guard and rescue craft: 63
  • Hydrographic survey vessels: 13
  • Aids to navigation evaluation vessels: 1
  • Buoy tenders: 2
  • Aids to navigation tenders: 18
  • Training boats: 3

AircraftEdit

The JCG operates 74 aircraft, these include:

  • Fixed Wing: 27
  • Helicopters: 46

VehiclesEdit

ArmamentsEdit

As described above, the JCG is not a military but a civilian organization, so the rules on the use of weapons are based on those of police officers, not self-defense officers.

Vessel-mounted weaponsEdit

Because the Allied countries wanted to maintain the disarmament of Japan, the weapons allowed to be carried by the MSA were restricted to only small arms in the earliest days. However, following the outbreak of the Korean War, the need to strengthen the security capability of Japan became necessary, and starting in 1954, the installation of larger guns on MSA ships began.[8]

Initially ships of the MSA were permitted to carry Mark 22 3"/50 caliber gun for large vessels (PL type), Bofors 40 mm L/60 guns for medium and small size ships (PM and PS type), and Oerlikon 20 mm L/70 guns were mounted on small patrol boats (ARB type and auxiliary submarine chasers). Actually, however, the number of 40 mm guns was insufficient, and many of the PS type had 20 mm guns installed instead.[8]

From the 1970s, substitution of these old guns began. The 3-inch guns were retired by 1979, as their age was progressing. Also from FY1978 an Oerlikon 35 mm L/90 gun was substituted on ships replacing the Bofors 40 mm L/60 gun, and from the FY1979 ships forward, the JM61-M 20 mm rotary cannons were installed on MSA ships in lieu of the earlier Oerlikon 20 mm guns.[8]

In the beginning, only a few of the 35 mm guns had a limited remote control function, most of these guns were manually controlled. Then, full-scale remote operation and automatic tracking function were included in the guns mounted on the PLH Shikishima introduced in 1989. In addition, the 20 mm gun systems were added to the standard equipment list as JM61-RFS, and they have been mounted on many patrol vessels. And in order to counter the heavily armed North Korean naval trawlers in the event of an engagement, most recently PLs have been equipped with a 40 mm L/70 gun or 30 mm chain gun remotely controlled with an optical director.[8]

Personal weaponsEdit

In the earliest days, MSA officers were issued WWII Nambu Type 14 semi-auto pistols and M1 rifles. Starting in the 1960s, the old semi-auto Nambu pistols were replaced by newly built M60 revolvers. More recently some security units of the JCG have been equipped with modern Smith & Wesson Model 5906 TSW pistols.[8]

Starting in the late 1960s, the M1 rifle was replaced, and sailors of the JCG were issued: Howa Type 64 rifles; and from 1990, their weapons were updated again to the Howa Type 89 rifles. In addition to these automatic rifles, SST is equipped with Heckler & Koch MP5A5/SD6 submachine guns. The Howa M1500 has been adopted as a sniper rifle, and the SST has also adopted anti-materiel rifles manufactured by the McMillan Firearms.[8]

HistoryEdit

In the Empire of Japan, coast guard operations were mandated for the Imperial Japanese Navy. But the Navy was dissolved with the surrender of Japan, and the ability of maintaining maritime order was declined seriously. Dense trade and smuggling had increased dramatically, even pirates had come to appear. Consultation between the Japanese government who wanted to restore public security capacity as soon as possible and the Allied countries wanting to maintain disarmament of Japan faced difficulties, but in 1946, an "Illegal Immigration Control Headquarters" was established in the Ministry of Transport, as cholera was transmitted to Kyushu by smugglers from the Korean Peninsula and was concerned to cause severe infection explosion.[10][11]

Meanwhile, the GHQ/SCAP also recognized the deficiencies of the Japanese coast guard system, and in March 1946, USCG Captain Frank M. Meals was invited to consider the situation. Captain Meals suggested the establishment of a comprehensive coast guard organization based on the USCG. In response to this, MSA was established as an external station of the Ministry of Transportation in 1948.[11] Its English name was changed to Japan Coast Guard in April 2000.[12] In 1952 the Coastal Safety Agency was created with ships supplied by the US and spun off in 1954 as the Japan Maritime Self Defense Force.

Minesweeping operationsEdit

Immediately after the end of the war, a large number of aerial mines laid by the US military were left in the waters around Japan, and the duty of clearing them became an important mission of the MSA. For this mission, minesweepers of the former IJN were incorporated into the MSA, and later, transferred to the Safety Security Force, ancestor of the Japan Maritime Self-Defense Force.[13]

In addition to activities in Japan's waters, in 1950, two flotillas of minesweepers were sent to the Korean Peninsula under the United Nations flag during the Korean War.[14]

Battle of Amami-ŌshimaEdit

On December 22, 2001, JCG ships intercepted a Chinese-flagged vessel believed to be North Korean in origin, in the Japanese Exclusive Economic Zone between Kyushu and China. When the vessel failed to respond, she was fired upon by the JCG and an exchange of gunfire resulted. The unidentified vessel sank in the Chinese EEZ with all hands.[15] The ship, later salvaged by the JCG, was found to be carrying weapons and spy equipment.[16] The wreck and its contents were put on display at the Japanese Coast Guard Museum at Yokohama.[17]
