Stretched
Repeated incursions into Japanese territorial waters, as
Tokyo defines them, is putting a severe strain on the Japanese Coast Guard,
which is the agency tasked with maintaining Japan’s control over the
controversial Sentaku islands in the middle of the East China Sea, known to
Chinese as Daioyu.
Normally thought of in terms of rescuing sailors in peril on
the sea, the coast guard in recent months has, in effect become the fourth
branch of the armed forces and the first line of defense in this quasi-sea
battle with boats and other sea craft from China and Taiwan.
Fortunately, the confrontations have been fought with water
cannons rather than real cannons. Even so, it is putting a strain on the coast guard,
which boasts about 12,000 members and about 400 vessels of various sizes and missions
ranging from buoy tenders to large, ocean-going armed patrol vessels.
The 11th coast guard district headquartered at
Naha, Okinawa, has nine patrol cutters, but they have been augmented by drawing
on vessels from other parts of Japan. By various accounts, as much as half of
the patrol force has been deployed to the East China Sea to maintain Japan’s
sovereignty over the islands.
At the same time, it has been called on to handle more traditional
coast guard duties. September saw the coast guard rescue 12 sailors on a
Chinese freighter that caught fire in the Sea of Japan and also rescue sailors
on a fishing boat that collided with a cargo ship off Japan’s northeast coast.
For several years Tokyo has been quietly beefing up the
coast guard, both by acquiring newer and larger cutters but also expanding the
service’s duties and loosening regulations that guide their activities. Just
this summer the parliament passed a law allowing the guard to arrest alleged
lawbreakers rather than have to depend on regular policemen.
It has other semi-military duties such as maintaining a
special anti-terrorism squad, and its mission to guard Japanese territorial
waters has greatly expanded with the advent of 200 nautical mile economic
exclusion zones. Even without counting the resources surrounding the Senkaku,
Japan still has far more undisputed EEZs
than China or Korea.
The Coast Guard also provides Tokyo a handy way around the
country’s constitutional prohibitions on maintaining an armed force. True,
Tokyo the provisions have not prevented Japan from raising a formidable military,
known euphemistically as Self-Defense Forces, yet Japanese armament is a
politically sensitive issue both at home and abroad.
The coast guard comes under the administration of the
Ministry of Lands, Infrastructure, Transport and Tourism, not the ministry of
defense, so it is possible to boost its budget without breaking the informal
rule that defense spending not exceed 1 percent of gross domestic product. While
regular defense budgets have declined in recent years, the budget for the coast
guard has risen ten-fold in the past couple decades.
“While the [Japan Coast Guars] has a long way to go to
become a fully modernized and militarized service branch, the transformation
may be the most significant and least heralded Japanese military development
since the end of the Cold War,” writes Richard J. Samuels of the MIT Center for
International Studies, one of the few academics who has paid much attention to
the coast guard.
Coast Guard commanders have more discretion to use their
weapons than the navy. In fact, it was involved in the only running sea battle
in Japan since the end of World War II, The incident in December, 2001, near the coast of Kyushu pitted several
cutters against a suspicious vessel thought to be a North Korean “spy” ship.
The Japanese coast guard fired warning shots to stop the
ship and then fired directly into the bow. The North Koreans returned fire with
automatic rifles, wounding a couple guardsmen, but did not use the ZPU
anti-aircraft cannon it with which it was equipped. Eventually the Koreans scuttled
the ship and all ten crewmembers went
down with it.
Tokyo was interested enough in what this vessel was up to
that it took the trouble and considerable expense of raising the vessel from 90
meters of water. It is now on display at the Japan Coast Guard Museum in
Yokohama. Indeed, it is virtually the only exhibit. Cannon holes are clearly visible
in the bow
Besides strengthening its conventional naval power, China has
also been beefing up its comparable fleet of ocean research vessels and armed fishery
monitoring vessels, some of which have been deployed in the South China Sea to
police its claims in that sea as well as to assert its claims in the East China
Sea.
These vessels are armed with machine guns, and probably
could not hold their own against some of Japan’s larger patrol vessels equipped
with 20 mm or 40 mm cannon should the two sides escalate their confrontation from
water cannons to something that actually involves exchanging gunfire.
However, despite their armament, coast guard vessels are not
true warships. They lack the weapons, armament and sensors necessary to survive
modern naval battles. They have no torpedoes, anti-ship cruise missiles, sonar
or anti-submarine defenses. No cutter would last ten minutes in a battle with a
modern Chinese destroyer.
Fortunately, things have not advanced that far. The main
worry in the Senkaku dispute is that the Chinese or Taiwanese, or both acting
together, would “swarm” the islands territorial waters overpowering the coast
guard by sheer numbers. That is what the Taiwanese attempted on Sept. 24, by sending
40 fishing vessels and 12 Taiwan coast guard vessels into the territorial
waters.
Still it works both ways, as Chinese and Taiwanese fishermen
might prefer to actually do some fishing rather than serve as (water)
cannon fodder. Both sides seemed to
welcome the approach of a typhoon early October that sent the vessels temporarily
scurrying to the shelter of home ports.
So far the expansion of the Japanese coast guard has not upset
Japan’s neighbors in Northeast Asia and that may be a good thing as the coast
guard can perform more missions that if executed by the regular navy would be
considered dangerously provocative.
