Japan extends ADIZ into Taiwan space

Japan has extended its Air Defense Identification Zone (ADIZ) so that it now overlaps with sections of a zone controlled by Taiwan, but foreign affairs officials said yesterday that would not make any difference in practice, as an understanding has been reached between the two parties on how to handle the sensitive matter.

A Ministry of Foreign Affairs (MOFA) official said on condition of anonymity that Tokyo informed Taipei “one or two days ago” that its extension of the ADIZ from Yonaguni Island westwards would come into force yesterday.

An ADIZ is an area of airspace defined by a country within which identification and location of an ­aircraft is required. Aircraft entering an ADIZ are required to radio their intended course and destination to the country’s air traffic controller, usually both civilian and military.

This was the second time Japan notified Taiwan about the extension plan following a statement by the ministry accusing Tokyo of informing Taipei without consulting it first.

The plan was first reported by the Sankei Shinbum on May 26, five days after the first notification to Taiwan.

The official said Tokyo had no intention of communicating with Taipei on the matter either before the decision was made by the administration of then-Japanese prime minister Yukio Hatoyama, nor after the ministry issued a statement on May 29 expressing “regret” over Japan’s unilateral move.

“Given international norms that ADIZ demarcation is at the discretion of each country, it was natural for Japan not to seek prior approval from Taiwan. However, when there is another country adjacent to the line, consulting with the country in advance is a courtesy,” the official said.

The original ADIZ between Taiwan and Japan runs along longitude 123 degrees east and splits the airspace over Yonaguni Island in half, leaving the area east of the line to Japan and the area west to Taiwan. The line was drawn by the US military after World War II.

The Japanese Ministry of Defense officially announced the new ADIZ line on its Web site on ­Thursday. Starting yesterday, the ADIZ was extended by 12 nautical miles (22km) from the baseline, with an additional 2 nautical miles as a buffer zone, resulting in an overlap with airspace over which Taiwan holds jurisdiction.

In a telephone interview, Minister of Foreign Affairs Timothy Yang (楊進添) said the government insisted the Taiwan-Japan ADIZ demarcation line “remain unchanged.”

“Each country is entitled to draw its ADIZ. When it comes to overlapping areas, we know how to deal with it. I believe we [Taiwan and Japan] understand each other’s position,” Yang said.

During a meeting at the legislature’s Foreign and National Defense Committee on May 31, Yang agreed to a suggestion by Chinese Nationalist Party (KMT) Legislator Lin Yu-fang (林郁方) that the government ask Japanese aircraft entering Taiwanese airspace in the zone to leave.

Asked by the Taipei Times if this position still held, Yang said “it would depend on the situation.”

“The Ministry of National Defense [MND] is in charge of that issue. However, if, in our judgment, something threatens our airspace, we could have a different reaction,” he said.

MOFA issued a second statement on Thursday night, again expressing “extreme regret” over the rezoning plan and reiterating its opposition to the change.

“There is no possibility the government will make any concession on this issue as it is a matter of national sovereignty,” ministry spokesman Henry Chen (陳銘政) said.


Chen said Taiwan and Japan would not engage in provocations as both sides had made their positions on the matter very clear.

KMT Legislator Liao Wan-ru (廖婉如) said later yesterday that the government should continue requesting negotiations with Japan on the matter.

“The problem isn’t that the ADIZ cannot be redrawn, but rather that Japan should have consulted us instead of making the decision on its own,” Liao said.

Defense ministry spokesman Major General Yu Sy-tue (虞思祖) said yesterday the ministry had a similar position.

Likening the ADIZ issue to the controversial Diaoyutai (釣魚台) Islands, over which Taiwan and Japan claim sovereignty, Chen said both sides would set differences aside and seek acceptable solutions through negotiations.

On reports by Japanese media that the expansion of the ADIZ was part of the Japanese government’s response to a military buildup in China, Yang refused to comment.


The anonymous official said the rapid growth of the Chinese military in recent years had become a concern for the academic and diplomatic community in Japan.

Democratic Progressive Party Legislator Peng Shao-chin (彭紹瑾) told the Taipei Times last night that Taiwan’s government had to learn how to strike a balance between its relationship with China and with the US-Japan security alliance.

“Japan’s redrawing of the ADIZ suggests that it might not trust Taiwan as much as it used to in light of our government’s moving too close to China,” Peng said.

Shouting matches and minor clashes erupted at the National Palace Museum yesterday after officials turned down a request by Tibetans and activists to present a photo of the Dalai Lama to “fill the missing part” of an exhibition on Tibetan Buddhist art.

“The Dalai Lama is the highest spiritual leader in Tibetan Buddhism. How could a portrait of the Dalai Lama be missing at an exhibition about Tibetan Buddhism?” asked Regional Tibetan Youth Congress-Taiwan (RTYC-Taiwan) chairman Tashi Tsering, wearing a traditional Tibetan outfit and holding up a large portrait of the Dalai Lama.
