• Japan scrambled fighters for Chinese Y-9 spy flights five days in a row.
• Flights occurred over the East China Sea from September 3 to September 7, 2026.
• No incursions into Japanese territorial airspace were reported.
• A Russian Il-20 also triggered a fighter scramble on September 5, 2026.

This series of incidents may indicate increased Chinese surveillance activity in the region, which could heighten tensions between Japan and China. The involvement of Russian aircraft suggests a broader pattern of intelligence-gathering flights, which may have implications for regional security and defense strategies.
