Japan’s Ministry of Defense reported a sharp increase in Air Self-Defense Force emergency fighter scrambles in December 2025, with aircraft launched 79 times to intercept foreign military aircraft approaching Japanese airspace, according to data released by the Joint Staff Office on January 16, 2026.
The total represented an increase of 46 scrambles compared with November and marked the highest monthly figure recorded in the second half of the year, the ministry said. The data covers the period through December 31, 2025, and reflects airspace monitoring operations conducted nationwide.
According to the Joint Staff Office, Chinese military aircraft accounted for 53 of the December scrambles, while Russian aircraft were responsible for 23. An additional three launches were attributed to aircraft categorized as “other,” a designation used when origin is not immediately confirmed. No scrambles were recorded in response to North Korean or Taiwanese aircraft during the month.

The December figure brought the total number of scrambles for the 2025 calendar year to 448, continuing a pattern of elevated air activity near Japan that has been observed throughout the year. The monthly data shows that scramble activity peaked twice in the final quarter, with 71 launches in October and 79 in December, following a brief dip in November.
Regionally, most of the December scrambles occurred in Japan’s southwestern airspace, which recorded 54 launches, according to the ministry’s breakdown. Northern airspace accounted for six scrambles, western airspace for 11, and central airspace for eight. The southwestern region, which includes approaches near Okinawa and the East China Sea, has consistently recorded the highest activity throughout 2025.
As noted by the Joint Staff Office, the majority of Chinese aircraft activity continued to originate from the East China Sea and the western Pacific, including flights that transited between Taiwan and Japan’s southwestern islands. Russian aircraft activity was primarily observed near northern Japan and the Sea of Japan, consistent with previous years’ patterns.
Japan’s emergency scrambles are conducted when foreign military aircraft approach its airspace without prior notification or when their flight paths raise concerns about airspace security. The missions typically involve F-15 or F-35 fighters identifying the aircraft visually and escorting them away from Japan’s airspace. No airspace violations were reported in December, the ministry said.
The Ministry of Defense emphasized that scramble figures reflect operational responses and not hostile actions. Still, officials noted that the sustained tempo places a continuous burden on personnel, aircraft, and maintenance cycles across the Air Self-Defense Force.

Japan fighter aircraft were scrambled 448 times in the last nine months – a 14 percent decrease from the same timeframe last year – in response to Chinese and Russian aircraft, Japan’s Joint Staff Office reported Friday.
From April 1 to Dec. 31, 2025, Japan’s Air Self-Defense Force scrambled fighter jets 448 times to shadow aircraft that approached and entered its Air Defense Identification Zone (ADIZ). The documented scrambles marked a decrease of 73 instances compared to 521 scrambles in 2024 during the same timeframe, according to the Japan Joint Staff Office.
Japan routinely scrambles its fighters to intercept and shadow Chinese and Russian aircraft in its ADIZ on the basis of national security. ADIZs are areas over land and water where transient aircraft can be tracked and identified on the basis of the monitoring country’s national security.
Figures released by the JSO show that as of Dec. 31, 2025, 304 scrambles – or 68 percent – were to shadow Chinese aircraft scrambles to shadow or intercept Russian aircraft make up 29 percent – or 130 instances. Additionally, one scramble was to shadow Taiwanese aircraft, and 13 were against other countries, which total a combined three percent. Japan did not release additional details on scrambles under the “others” category.
In comparison, during the same period in 2024, Japan conducted 345 scrambles to shadow or intercept Chinese aircraft, totaling 66 percent of fighter scrambles. Another 173 scrambles – or 33 percent – were in response to Russian aircraft. There were no scrambles in response to Taiwanese aircraft, but there were three in response to aircraft from unspecified countries.
A map issued with the report shows almost all Chinese flights took place around Japan’s southwest islands with a large number passing between Okinawa and Miyako Island or between Yonaguni Island and Taiwan. Meanwhile, the majority of Russian flights were north and west of the main island of Hokkaido and west of the northern and central part of the main island of Honshu. Joint flights with both Chinese and Russian aircraft spanned the southwest region.

The data reflects an overall 14 percent decrease in fighter scrambles, as well as an 11 percent decrease and nearly a 25 percent decrease in scrambles in response to Chinese and Russian aircraft, respectively.
Despite the overall decrease in scrambles, Japan documented 35 instances of notable and unusual flight activity, of which 12 occurred from Oct. 1 to Dec. 31, 2025. The Joint Staff Office does not define unusual flight activity, but it typically includes activity not encountered regularly or significant activity due to the aircraft involved or its flight pattern. Japan releases information on the flights it deems to be of interest to the Japanese public.
The most recent instances of notable and unusual flight activity include: flights by Russian Tu-95 bombers and fighter jets in the Sea ofJapan, 260 sorties of embarked fighter aircraft and helicopters from People’s Liberation Army Navy (PLAN) aircraft carrier CNS Liaoning (16), long-distance joint flights by Chinese H-6 bombers and Russian Tu-95 bombers and transits between Okinawa and Miyako Island by Chinese H-6 bombers and fighter jets. Additionally, on Dec. 6, a J-15 fighter jet taking off from Liaoning intermittently illuminated radar on a JASDF F-15 fighter jet that was conducting airspace violation measures against the J-15.
Four of the latest instances spanned Dec. 6-12 and included PLAN J-15 fighters taking off from Liaoning.
Another three entries covered Russian IL-20 Electronic Intelligence aircraft flights, of which one flew over the Sea of Japan and Sea of Okhotsk on Oct. 10. The second of the three instances covered the Oct. 25 flight over the Sea of Japan, and a third on Oct. 29 that saw the Russian aircraft make a round trip from the Sea of Japan to the Sea of Okhotsk and the Pacific Ocean. Additionally, on Oct. 24, two Russian TU-95 bombers escorted by two SU-35 fighters flew over the Sea of Japan.
Later, on Dec. 9, there was a joint bomber flight between two Russian Tu-95 bombers and two Chinese H-6 bombers from the East China Sea to the coast of the main island of Shikoku. That same day eight Chinese J-16 fighters, two Russian Su-30 fighters and a Russian A-50 Airborne Early Warning and Control (AEWC) operated around Japan.
Two entries were for suspected Chinese Unmanned Aerial Vehicles (UAVs) on Nov. 15 and Nov. 24. In both cases a single suspected Chinese drone flew in from the East China Sea, passed over the waters between Yonaguni Island and Taiwan to enter the Philippine Sea and conducted a circuit flight before returning back to the East China Sea via the same route.
The latest reported instance was Dec. 29, the same day the PLA began its “Justice Mission 2025” drills against Taiwan. Two Chinese H-6 bombers, two Y-9 Electronic Intelligence (ELINT) aircraft, two J-16 fighters and two presumed Chinese fighter aircraft arrived from the East China Sea, passed between Okinawa and Miyako Island to enter the Philippine Sea and later turned back, passing between Okinawa and Miyako Island to enter the East China Sea.
