Japan intercepts new Chinese Y-9FQ maritime patrol aircraft over Sea of Japan
March 31, 2026
On the 28th of March, the Japan Air Self-Defense Force (JASDF) intercepted a rare next-generation Chinese People’s Liberation Army Naval Air Force (PLANAF) Y-9FQ maritime patrol and anti-submarine aircraft over the Sea of Japan.

In a statement, the JASDF wrote, “The Air Self-Defense Force’s Southwest Air Defense Force’s fighter aircraft conducted scramble operations in response to one Chinese military patrol aircraft (Y-9) that flew over the East China Sea.”

The statement adds that, while various Chinese aircraft have been intercepted in this region before, this time it was different.
It elaborates, “the aircraft confirmed this time has a different shape in the nose (frontmost part) compared to previous aircraft, and this is the first time the Self-Defense Forces have confirmed and announced such an aircraft.”
USNI News says this is likely the improved (Y-9YQ) version of the earlier Y-9 MPA, designated the Y-8Q. The Aviationist notes that another older surveillance aircraft, a KQ-200 ASW-MP/MR, was also spotted during the intercept.

The Y-8Q first entered service in 2015, while prototypes of the improved version emerged in 2022.

Russian aircraft also patrolled near Japan
According to USNI News, this is part of a greater number of Russian and Chinese spy aircraft being tracked around Japan over the weekend, as the world’s attention is squarely on Iran and the US-led air campaign.

On Friday, two Russian Tu-142 Maritime Patrol Aircraft patrolled through the Sea of Okhotsk to the Sea of Japan, triggering Japan to scramble aircraft. Tu-142s are maritime reconnaissance and anti-submarine warfare (ASW) aircraft developed from the Tu-95 turboprop strategic bomber.
Japanese naval vessels also shadowed the Russian surveillance ship Pribaltica (80).
While Russia’s attention may be focused on Ukraine, it has a complicated relationship with Japan. One complication is the disputed Kuril Islands north of Hokkaido, which Russia claims and controls and Japan sees as occupied territory.
Russia has also routinely patrolled North Atlantic waters, forcing the RAF to scramble from RAF Lossiemouth in Scotland. Seperately, Russia’s patrols around Alaska are often intercepted with F-22 Raptors.
One of the main aircraft Russia uses for these patrols is its Tu-95MS ‘Bears’, although it’s unclear how many remain operational after losses in Operational Spiderweb and wartime fatigue.
Tense relations between Japan and China
Japan’s Defense Minister Shinjiro Koizumi posted on X (formerly Twitter), “Even at this very moment, as the world’s attention is focused on the Middle East, the Ministry of Defense and the Self-Defense Forces never cease their surveillance and monitoring activities around Japan…”
Tensions between Japan and China are high. Japan is becoming ever wary of its increasingly confident larger neighbour, while China is concerned by the reelection of Japan’s firebrand Sanae Takaichi as prime minister.
Japan is taking steps to rearm and counter China’s influence in the region. Japan’s force posture is focused on area denial, including its southern Ryukyu Islands.
The development also comes after a seemingly inexplicable lull in Chinese violations of Taiwanese airspace that started (perhaps coincidentally) around the time of US strikes on Iran.
NEW: According to multiple sources, KMT Chair Cheng Li-wun has accepted an invitation to lead a delegation to China in early April, where she is expected to meet with President Xi Jinping.

Prime Minister Sanae Takaichi has stated that a Chinese invasion of Taiwan would also pull in Japan, calling such a scenario “a survival-threatening situation” (sonritsu kiki jitai).
Among other things, Japan sees Taiwan as vital to its security and to preventing China from surrounding it and cutting off its sealanes. China sees Japan’s southern islands with US military bases and Taiwan as hemming it in.
