Branch by branch
| Budget Advantage: China | China. An announced 1.91 trillion yuan for 2026, about $277bn and up 7 per cent. The real total is higher, and Silent Dossier's estimate runs up to $377bn. | Japan. JPY 9.04 trillion for FY2026, about $58bn and 1.4 per cent of GDP. With related security spending the total is about JPY 10.6 trillion, near 2 per cent. |
| Air power Advantage: China | China. An estimated 1,650 fighters, more than 300 of them J-20 stealth jets, with some 230 H-6 bombers, about 50 early warning aircraft and 25 tankers. | Japan. An estimated 330 fighters: about 200 F-15Js, 90 F-2s and 40 to 50 F-35s, five of them F-35Bs at Nyutabaru since February 2026. The plan is for 147 F-35s. |
| Naval Advantage: China | China. More than 370 ships and submarines, three carriers, an estimated 45 to 50 modern destroyers led by about ten Type 055s, and 62 submarines. | Japan. About 38 destroyers, eight of them Aegis ships, ten Mogami frigates and 24 conventional submarines. Izumo's carrier conversion ends in FY2027 and Kaga's in FY2028. |
| Missiles Advantage: China | China. About 3,100 ballistic missiles at the end of 2024, from 900 short range to 400 intercontinental types, the longest reaching an estimated 13,000 km. | Japan. Cruise missiles for counterstrike: Tomahawks with a 1,600 km reach, arriving since March 2026 from 400 ordered, and the Type 25, with a reported 1,000 km range, deployed the same month. |
| Air and missile defence Advantage: China | China. An estimated 110 to 150 long-range batteries of HQ-9, HQ-9B, S-300PMU and S-400. | Japan. An estimated 16 to 28 Patriot PAC-3 fire units and eight Aegis destroyers. Two more Aegis-equipped ships are due in FY2027 and FY2028. |
| Land forces Advantage: China | China. About 2.03 million active troops, 510,000 reservists and an estimated 5,000 tanks, some 500 to 650 of them Type 99 and 99A. | Japan. About 218,000 active troops, short of the 247,000 authorised, plus 56,000 reservists and an estimated 400 Type 10 and Type 90 tanks. |
| Nuclear Advantage: China | China. An estimated 620 warheads at the start of 2026, carried by land-based missiles and six Type 094 submarines. | Japan. No warheads. Silent Dossier classes Japan's nuclear status as latent. |
| Alliances Advantage: Japan | China. A 1961 treaty with North Korea, a base in Djibouti and a strategic partnership with Russia. | Japan. The US-Japan Security Treaty, with about 55,000 US troops in Japan, and Reciprocal Access Agreements with Australia, the UK and the Philippines. |
If it came to war
| Scenario | Short war | Long war |
|---|---|---|
| An air and sea clash in the East China Sea | Even Japan fights close to its bases with Aegis destroyers, 24 submarines and F-35s, while Chinese strike power is thought to be most effective within 1,500 to 2,000 nautical miles of the mainland, a radius that covers Japan. | China J-20 output runs at an estimated 100 a year and new Type 055s keep joining the fleet. Japan already struggles to crew its ships, so losses would be harder to replace. |
| A missile campaign against Japanese bases | China An estimated 1,300 Chinese medium range missiles would face some 16 to 28 Patriot fire units and the Aegis fleet. | China Japan can now strike launch sites and ports with Tomahawk and Type 25 missiles, but 400 Tomahawks on order cannot match China's stock. |
Could Japan hold off China in a war?
Not on its own. China has about 2.03 million active troops to Japan's 218,000, an estimated 1,650 fighters to Japan's 330, and more than 370 ships and submarines against a Japanese fleet of roughly 155. Its rocket force held about 3,100 ballistic missiles at the end of 2024, and Chinese strike power is thought to be most effective within 1,500 to 2,000 nautical miles of the mainland, a radius that takes in every Japanese base. China also has three carriers and an estimated 620 nuclear warheads, and Japan has neither.
Japan would not fight alone, and the alliance narrows the gap. The US-Japan Security Treaty keeps about 55,000 US troops in the country. Japan's own force is modern at sea and in the air, with eight Aegis destroyers, 24 submarines and an estimated 40 to 50 F-35s. Neither side has recent war experience: China's last war was in 1979, and Japan has not fought since 1945.
Which country has the bigger military budget, China or Japan?
China, by almost five times on announced figures. Beijing set its 2026 defence budget at 1.91 trillion yuan, about $277bn and 7 per cent more than the year before. Silent Dossier puts real spending as high as $377bn, from an economy of about $19.5 trillion.
Japan's defence ministry has JPY 9.04 trillion for FY2026, about $58bn and up 3.8 per cent, the largest budget the forces have had. That is 1.4 per cent of an economy of about $4.1 trillion. Adding related security spending brings the total to about JPY 10.6 trillion, which Tokyo counts as meeting its 2 per cent of GDP goal. The difference shows on the production lines: China builds an estimated 100 J-20s a year, while Japan plans to buy 147 F-35s in all.
How does Japan's military power compare with China's at sea?
This is where Japan comes closest. It has about 38 destroyers, eight of them Aegis ships of the Maya, Atago and Kongo classes, against an estimated 45 to 50 modern Chinese destroyers led by about ten Type 055s. Japan's ten Mogami frigates are the parent design of the three Upgraded Mogami ships Australia signed for on 18 April 2026, a deal worth about $6.5bn.
Under water, Japan's 24 Taigei and Soryu submarines face a Chinese force of about 62, including six Type 094 ballistic missile boats and an estimated 10 nuclear attack submarines. China also has the only carriers in this contest. Liaoning, Shandong and Fujian are in service, and Fujian launches aircraft with electromagnetic catapults. Japan's Izumo is being converted to fly F-35Bs and should finish in FY2027, with its sister Kaga following in FY2028.
Can Japan strike targets in China?
Since March 2026 it has had the missiles to do so. Tomahawks from an order of 400, worth about $2.35bn, began reaching the navy that month, and the Aegis destroyer Chokai made Japan's first live Tomahawk firing on 29 July 2026 in a drill with the US Navy. The Tomahawk reaches about 1,600 km. The ground-launched Type 25, an upgraded Type 12 with a reported range of about 1,000 km, was deployed at Camp Kengun in Kumamoto in March, and an F-2 flew a captive-carry test of an air-launched version on 30 July.
Japan's arsenal is small beside China's. Against 400 Tomahawks, China held an estimated 900 short range, 1,300 medium range and 500 intermediate range ballistic missiles at the end of 2024, plus about 400 intercontinental missiles. Japan's defence against such a salvo rests on an estimated 16 to 28 Patriot PAC-3 fire units and its Aegis ships, and Tokyo plans to revise its three main security documents in December 2026.
What holds each military back?
For Japan, it is people. Its forces stood at about 88 to 90 per cent of the 247,000 authorised in FY2025, and the navy is the worst affected. That year's intake of 11,177 recruits was the first above 10,000 in three years and still missed its target, after about 5,600 mid-career personnel resigned in FY2024. Pay rises are meant to slow the losses.
For China, it is command. Purges of senior officers have run through the Rocket Force and the Central Military Commission since 2023. On 29 October 2026 the Communist Party's Fifth Plenum confirmed the expulsion of 33 Central Committee members, among them former commission vice-chairman Zhang Youxia and former Joint Staff chief Liu Zhenli, and about 16 of the 33 reportedly came from the military. Their seats on the commission have not been filled.
