Overview
- The 2025 defense white paper formally identifies China’s rapid military buildup as Japan’s most serious strategic challenge since World War II.
- Chinese naval transits off southwestern Japan have tripled over three years and PLA operations now extend beyond the first island chain into the Pacific.
- Two separate encounters in the East China Sea saw Chinese JH-7 fighter-bombers close to within 30 m and 60 m of a Japanese YS-11 intelligence aircraft.
- The report warns of growing China-Russia joint drills near Japan and describes North Korea’s advance of nuclear-capable missiles as an increasingly imminent threat.
- To counter these risks, Japan will raise defense spending to 2 percent of GDP by 2027, deploy long-range cruise missiles on its southwestern islands and deepen U.S. and regional security partnerships.
