Diaoyu Islands: regional tensions with China have increased since Japan’s nationalisation a decade ago
- In 2012, the Japanese government put the disputed islands – called the Senkakus by Tokyo and the Diaoyus by Beijing – under state control

On September 11, 2012, the Japanese government of then Prime Minister Yoshihiko Noda put the islands under state control, five months after then Tokyo Governor Shintaro Ishihara abruptly announced the metropolis would buy some of the disputed islands from a Japanese private owner.
Subsequently, communist-led China has stepped up provocations in the nearby waters, frequently sending its coastguard vessels near the islets, destabilising the regional security environment. Beijing has insisted the islands are its “inherent territory”.

“We cannot let our guard down against China, given its apparent ambition to change the status quo by force,” a Japanese government official said. “The nationalisation gave us a cue to seriously reconsider our defence policy with a high sense of urgency.”
The islands are under the jurisdiction of Japan’s southern island prefecture of Okinawa – a geopolitically important region that still hosts the bulk of US bases in the country over 50 years after it was reverted to Japan in 1972 following US rule.
During a campaign for the Okinawa gubernatorial election on Sunday, three candidates focused on security issues, including the long-running issue of the relocation of a key US Marine Corps base that would work as a deterrent against China.
In April 2012, Ishihara, Japan’s foremost nationalist who died earlier this year at the age of 89, unveiled his controversial plan to purchase the Diaoyu Islands during his speech at the Heritage Foundation, a Washington-based conservative think tank.
China, meanwhile, overtook Japan as the world’s second-biggest economy that year, prodding Ishihara to believe it became impossible to challenge China’s military build-up without US support, said the source who worked for the Tokyo metropolitan government.
Ishihara served as Tokyo Governor for 13 years from 1999 after nearly three decades in national politics.
“Before he became Tokyo Governor, Ishihara, an ocean lover, was earnestly interested in the situation surrounding the Senkaku Islands and highly vigilant against China’s military expansion,” the former municipal government official said.
During his first campaign for the gubernatorial race, Ishihara lambasted Walter Mondale, a former US ambassador to Japan, for saying that Washington would not be compelled by the 1960 treaty to intervene in a dispute over the Diaoyu Islands.
Mondale was the US ambassador to Japan for three years through 1996 under the administration of then President Bill Clinton.
“Despite China’s rising assertiveness in the region, the United States may not have backed Japan even in case of a contingency in the East Chain Sea, while Japanese citizens lacked a sense of crisis. Ishihara was irritated,” the former official said.
In the wake of Ishihara’s surprise speech, the Japanese government began to strongly emphasise the significance of its security alliance with the United States, and public awareness of national security against China has clearly increased in Japan.

“Ishihara would have been satisfied, as his speech might have motivated the United States and the Japanese public to confront China,” the former official added.
Critics, however, shrug off the view that the move by Ishihara, which eventually put pressure on Noda to nationalise the disputed islands, was irresponsible and triggered a sharp deterioration of ties between Japan and China.
For years after the nationalisation, Japanese living in China had been forced to refrain from speaking their language in public due to intensified anti-Japan sentiment, said Masaru Kaneko, a 56-year-old Japanese businessman in Beijing.
Sino-Japanese relations “nosedived” after the nationalisation and “have never really recovered despite some fluctuations,” said Jeff Kingston, director of Asian Studies at Temple University Japan.
To achieve peace and stability in the region, Japan should “seek deeper diplomatic dialogue and greater engagement” with China to expand common ground on the occasion of the 50th anniversary of the normalisation of diplomatic ties, he added.
