The project was to maintain Japan’s interest in the sea far
south from its mainland. Five were killed and two are still missing in the
accident around the southernmost land of Japan. They were workers for a
construction to reinforce the small island to survive waves and winds. It
reminded of China’s dispute that those islands were too small to call “land.”
The accident invoked that unstable situation in East China Sea was not only
about Senkaku Island.
The workers were at the operation of sliding a huge footing
with piles from the deck of a ship to the sea surface. After the move, the
footing would be floating on the sea and piles would support it standing on the
sea base. In spite of top constructors in Japan joining the project, the
accident happened unexpectedly. While the companies are investigating the reason
why the footing fell down, some think that rough waves tore down the architecture
with unstable structure.
The project was to protect a coral reef, which had been
named Okinotorishima, Japan’s southernmost island on the Pacific Ocean. Located
one thousand miles away from Tokyo, the island possesses 420 thousand square
kilometers of exclusive economic zone. While the reef has seven square
kilometers, constant land without sinking below the sea surface is quite small.
Officially registered land has only nine square meters.
That was why the government of Japan started the project to
surround the land with concrete buildings to protect the island in 1987. After
finding of rare metal in the sea base around the island, Japanese government
began to build a new port with a cost of ¥75 billion. When the project is
completed, the footing would become a pier for researching ships.
China is appealing the island is not simply an island, but a
rock on the ocean, which does not consist of land for EEZ. It is considered to
be China’s interest in raw materials around there and further advance in the
East China Sea. The Coastguard of Japan confirmed two Chinese ships cruising in
the EEZ without notification to Japan last July.
Although the island is unequivocal territory of Japan, the
accident spotlighted the existence of dispute over Okinotorishima. Japanese
government wanted to finish the project without being acknowledged by the
public. Silent effort of maintaining Japan’s sea interest was revealed by an
accidental event. In the situation of unstable relationship with China, the
government of Japan will need to raise its alert around Okinotorishima. It is
setting observation camera on the footing to watch unidentified attempt to land
the island, which may invite further dispute on it.
