The Senkaku Islands, a small uninhabited island group in the East China Sea, have been administered by Japan since 1972 and are also claimed by China, which calls them the Diaoyu Islands, and by Taiwan. China Coast Guard vessels regularly enter the contiguous zone and, at intervals, the territorial waters around the islands; Japan's coast guard tracks these vessels and at times acts to expel them. The dispute also extends to the wider East China Sea, where the two countries' exclusive economic zone claims overlap and where survey vessels, fishing activity and gas-field infrastructure near the median line have periodically drawn protest from Japan. The islands lie near Japan's Yonaguni and Ishigaki islands, within the broader geography of the first island chain.

Japan's position on Taiwan sits close to the center of its relationship with China because Taiwan lies at the edge of Japan's own southwestern island chain: a Taiwan Strait contingency would occur within reach of Japanese territory and shipping lanes. Japanese officials have at times described such a contingency as a matter engaging Japan's own security, including under the country's collective self-defense doctrine, and Japanese naval vessels have transited the Taiwan Strait. China regards Taiwan as an internal matter and treats foreign statements on it as bearing on its own sovereignty; Japanese remarks on the subject have prompted formal protests, demands for retraction, and diplomatic friction including incidents at each country's embassy. The dispute is distinct from the wider Taiwan Strait confrontation between China, Taiwan and the United States: its terrain is the bilateral Japan-China relationship, triggered by and centered on Japan's own statements and posture.
Administration framing (Japanese and Western press) treats the Senkakus as territory under Japanese administrative control and reads China Coast Guard entries into the surrounding territorial waters and contiguous zone -- along with survey ships, buoys and drilling structures placed near the median line -- as sustained grey-zone pressure intended to normalise a Chinese presence and erode that control without triggering armed conflict. Incidents are counted and protested rather than escalated.
JapanRights-protection framing (Chinese state media) holds that Diaoyu Dao and its affiliated islets have been Chinese territory since ancient times, that China Coast Guard patrols in the surrounding waters are routine and lawful rights-protection law enforcement in Chinese jurisdiction, and that Japanese vessels entering those waters are the intruders being lawfully expelled. Japanese protests are cast as provocation, and the friction is tied to Tokyo's accelerating remilitarisation rather than to Chinese activity.
ChinaJapan's postwar constitution renounces the use of force to settle international disputes and for decades constrained its military to a strictly defensive posture. Since the 2010s, Japan has raised its defense budget, developed long-range counter-strike missile capability, eased restrictions on defense equipment exports, and debated formal revision of Article 9 -- changes officials in Tokyo describe as a response to a more severe regional security environment, including Chinese naval and air activity near Japan's southwestern islands. Chinese officials and state media describe the same changes as a departure from Japan's postwar pacifist commitments and connect them to Japan's wartime history. The debate involves Japan's Self-Defense Forces, its defense budget process, and its security relationships with the United States and other partners.
