At 3:00 am on October 13th 1952, when 40 Japanese fishing boats including a fishing boat from Shizuoka prefecture called “Hokoku-Maru” were engaging in fishing squads within Japanese territorial waters at 30 miles east of Udo of Chejudo (Quelpart), three small warships of Korea suddenly machine-gunned them shooting tracer bullets.
And on both of 13th and 14th October, Japanese fishing boats including “Narita-Maru” and “Fukuei-maru” (both from Chiba prefecture), and four other fishing boats from Shizuoka prefecture were attacked by three Korean warships twice at around 20 to 30 miles southeast of Udo. At 11:00pm on October 16th, “Sunami-Maru” of Kanagawa prefecture was attacked by Korean warships at 30 miles east of Chejudo.
[The article said that Japan protested against Korea after revealing that it was an illegal shooting in the open waters.]
To follow is the details of the Daiichi Daihou Maru Incident in 1953:
In July 1954 Korea began to occupy the island. To follow is from a newsclip of the New York Times, July 31, 1954. This is how the illegal occupation of Liancourt Rocks by Korea began.
Japanese sources said today the South Koreans had seized
and occupied the Takeshima islands in the Sea of Japan. Title to the islands
long had been in dispute between the two nations.
Two Japanese patrol boats cruising near Takeshima saw a
half-dozen Koreans at work on Mishi Island [sic], one of two rocky islets that make up
the Takeshima group.
The men were uniforms of white shirts and green trousers.
Apparently they were guards sent by the Republic of Korea to enforce the claim
to Takeshima, the Japanese maritime Safety Board reported. It was not apparent
whether the men were armed, the report said, but they evidently intended to stay
on the island.
A large tent had been pitched on what looked like a
permanent foundation, coast guardsmen said. And on the northern side of Mishi a
large sign had been erected with the legend, "Republic of Korea, Seventh
District, Civil Administration Department".
The Japanese made no attempt to land, according to the
Maritime Board, but patrol boats circled the island, broadcasting through their
public address systems that the islands were Japanese territory. To this the
Koreans appeared to pay no attention.
The Japanese visit was made Wednesday by two patrol
ships, the Kuzuryu and Nagara. The Koreans, the Japanese assumed, had been in
posession at least since July 25, the date inscribed on the
The Japanese deduced that the Koreans' presence was not a
temporary stop-over, such as is sometimes made by fishermen at
No Korean vessel was in the vicinity, according to the
Japanese coast guards, leading to the belief the South Koreans had been embarked
on the island with supplies to last sometime.
Takeshima, lying at about Lat. 37 degrees 7 minutes N.
and Long. 131 degree 55 minutes E., consists of two islands, Nishi, the west
island, and Higashi, the east island. Earlier this month, the South Korean
Assembly in a formal proclamation asserted soverignty over both islets and a
party of Assemblymen was reported to have sailed from Pusan this week to inspect
The islands have been a bone of contention between Japan
and the Korean Republic since the San Francisco Peace Treaty of Sept.8, 1951,
restored independence to this nation.
The rocky barren islets, which cover only few square
miles, have served as a useful temporary base for fishermen trawling in the Sea
of Japan. According to the Japanese Foreign Office, the islands have been so
used by Japanese fishermen for more than 300 years and at one time were known as
Matsushima or Pine Islands. They were formally incoprporated into the Japanese
national territory in 1905.
Takeshima lay on the Japanese side of the "MacArthur
Line", established as a boundary beyond which the Japanese might not go during
the Allied occupation without special consent. Later, however, when President
Syngman Rhee of Korea set up the "Rhee Line", extending Korean territorial
waters far out into the Sea of Japan, the islands fell on the Korean side of the
The Japanese Government, though claiming posession of
Takeshima, apparently has not been able to decide, to date, what to do about
Korea's claims. Last year, answering questions in the Diet, Foreign Minister
Katsuo Okazaki told the members it was "clear by the San Francisco Peace Treaty
that Takeshima is an island of Japan." At that time he said he had "not heard"
of the Korean claim and did not believe the issue worth disputing.
Meanwhile, negotiations between Japan and Korea over
reparations, the establishment of regular diplomatic negotiations and other
issues have completely broken down. So far as is known, posession of the islands
has never been formally discussed, though each side has continued to advance its
own claim to the territory.
