Synopsis: The United States is bolstering its presence at Japan’s Misawa Air Base with additional F-35 fighters, a strategic move designed to extend the reach of 5th-generation air power to the Taiwan Strait and mainland China without relying on vulnerable tankers.
This deployment fortifies a “semi-circular” perimeter of allied stealth aircraft stretching from Japan and South Korea to the Philippines and Australia, effectively encircling China’s coastline.

US F-35 Fighters to Misawa Air Base: The “Semi-Circle” Strategy to Encircle China
48 new F-35A Lightning II stealth fighters will soon be based in Japan. And, clearly, the reason is China.
The location of those fighters is one the U.S. military is clearly familiar with. US forces first arrived at Japan’s Misawa Air Base in 1945 following the end of WWII, and have maintained a presence ever since, so it makes sense that the US would now be adding more F-35s to the area.
The tactical and strategic advantages are multifaceted, as the move not only puts more F-35s within reach to potentially defend Taiwan, but also positions 5th-generation attack air power to attack mainland China if needed, without necessarily requiring a non-stealthy tanker to extend range.
The F-35 can hit ranges up to 1,000 to 1,300 miles, so operating land-based F-35As from Japanese islands and coastal areas massively extends the “reach” of 5th-generation aircraft in the Pacific theater.

The advantages of Japan-based F-35s extend well beyond the clear value of proximity, including massive networking benefits.
The Japanese Self-Defense Forces have, in recent years, invested billions of dollars to acquire F-35 aircraft and now regularly operate Vertical Take-Off-and-Landing F-35Bs from amphibious ships and small mini-carriers in the Pacific.
Photographs of Japan’s mini-carriers were released by the JMSDF in 2024, showing a redesigned or refitted helicopter-carrying amphibious assault ship.
Called the “JS Kaga,” the newly configured amphibious carrier is designed to transport F-35s, troops, helicopters, and other power-projection and attack-enabling assets.
The vessel operates with a maximum displacement of 27,000 tons at full load and an 814-ft flight deck, a ship vastly smaller than US Navy carriers, which displace more than 100,000 tons.
US-Japanese F-35 Fighters
Flying operational F-35Bs from Japanese ships has been in development for several years, as the US Marine Corps conducted a joint US-Japanese multinational exercise in which Marine Corps F-35Bs landed on Japanese warships.
This clearly seems to have been a precursor to what is happening now with Japan’s growing fleet of “mini-carriers.”
The ability to fortify a Japanese maritime force of F-35s with US Air Force F-35As could prove decisive in any potential engagement in the Pacific, as it could allow a greater ability to mass 5th-gen air power in large, impactful formations across a perimeter in the Pacific spanning from Japan to the Korean Peninsula all the way down through the Philippines and Australia.
This could, in effect, almost encircle the Chinese coastline with F-35s, or at least form a semi-circular extended air-boundary sphere from which to defend against or attack PLA air and ground forces.
Japan Mini-Carrier Advantage
This capacity is quite significant because the US and its Japanese allies could potentially operate with a decisive 5th-generation air advantage.
China operates the J-20, but it is a land-launched platform incapable of projecting power from the ocean; the J-20 may also be more vulnerable to F-35s and F-22s, depending on the range and fidelity of its sensors and the range and accuracy of its weapons systems.
Regardless, the US and its allies are increasingly in a position to deploy a large force of F-35s to counter or contain China from the air. This kind of tactical thinking is likely a significant reason why the Japanese MOD is both acquiring F-35s and building mini-carriers.

Given this threat scenario, it makes sense that the Japanese JMSDF and the US would be rapidly acquiring F-35Bs and F-35Cs for the region.
All F-35s operate with a secure, high-speed data link called the Multi-Function Advanced Data Link (MADL), which enables networking across all countries operating F-35s.
This enables a multinational, large-scale, semi-circle-like formation of F-35s involving the US Navy, South Korea, and even Australia and Singapore further south.
The additional bases being added in the Philippines might also provide an opportunity for the US and its allies to deploy F-35s there and “fill in” a gap in the semi-circle between Japan, Australia, and Singapore.
