Analyst Assessment

Verdict
Edge: China

China's PLA Air Force holds a decisive overall edge over Japan's Air Self-Defense Force, fielding roughly 3,700 aircraft including some 2,000 combat types, 234 H-6 bombers and a growing J-20 force, against Japan's 1,397 aircraft and 331 fighters. Japan's counterweight is qualitative and structural: a uniformly modern F-15/F-2/F-35 fighter line, dense maritime ISR, and US alliance integration, but it fields no bomber or long-range strike arm.

Domain by domain
Fighter & multirole fleet Edge: China
🇨🇳 ChinaAbout 2,043 combat aircraft: 300 J-20 stealth fighters, 365 J-11, 271 J-10, but a long legacy tail of 417 J-7 and 143 J-8 that dilutes average capability.
🇯🇵 JapanOnly 331 combat aircraft, yet uniformly modern: 199 F-15 (largely upgraded), 85 Mitsubishi F-2, 47 F-35 with 100 more on order. Quality-dense, numerically outmatched roughly six to one.
Strike & bombers Edge: China
🇨🇳 China234 H-6 bombers give a cruise-missile-armed, theatre-range strike arm no regional peer matches, complemented by J-16 and J-20 strike-capable multirole fighters.
🇯🇵 JapanNo bomber fleet. Long-range strike rests on fighter-delivered stand-off missiles being introduced on F-15 and F-35, plus emerging indigenous programmes; capability is nascent and limited in mass.
ISR / AEW & tankers Edge: Japan
🇨🇳 China39 special-mission aircraft, mostly KJ-series AEW&C and Y-8/Y-9 derivatives, plus Y-20-based tankers; reach is expanding but thin relative to fleet size.
🇯🇵 Japan127 special-mission aircraft, including 49 P-3 Orion and 38 Kawasaki P-1 maritime patrol, E-2 Hawkeye AEW with 7 more on order, and KC-46 tankers arriving. Densest maritime ISR picture in the region.
Procurement pipeline & industry Edge: China
🇨🇳 China130 aircraft on order but 85 % domestic sourcing and a vertically integrated industry sustaining J-20, J-16, Y-20 and H-6 lines; replacement of J-7/J-8 proceeds from internal capacity.
🇯🇵 Japan353 aircraft on order — 100 F-35, 124 UH-1, P-1, KC-46, E-2 — a larger relative recapitalisation, but 67 % US-supplied, tying throughput and upgrades to foreign production lines.
Helicopters & rotary lift Edge: China
🇨🇳 China1,019 helicopters: 258 Mi-17, 175 Z-19, 141 Z-9, 130 Z-8, with Z-10 and Z-19 on order. Broad domestic rotary base oriented to continental manoeuvre.
🇯🇵 Japan533 helicopters: 140 UH-1, 101 UH-60, 100 SH-60, 72 CH-47, 50 AH-1, with 124 UH-1 and 17 CH-47 ordered. Smaller, but naval and island-support oriented.
Wildcards
  • Alliance access and integration Japan operates alongside sizeable US air and naval forces based on its territory, with shared tankers, AEW data links and munitions stocks. That coalition depth is not captured by national inventory counts.
  • Geography and basing Japan's archipelago offers dispersed but finite, targetable airbases within reach of Chinese missiles; China gains mass and depth but must project across water, where Japanese maritime ISR and interceptors concentrate.
  • Legacy fleet drag Roughly 560 J-7 and J-8 airframes inflate China's combat total without contributing modern capability. The usable high-end force is closer to 900-1,000 aircraft, narrowing the effective gap.
  • Combat experience Neither air force has recent sustained combat experience. Both rely on exercise tempo and readiness rates; Japan's high scramble rate and 296 trainers support continuity, China's larger fleet strains maintenance and aircrew throughput.
