Japan's military doctrine, built for decades on the use of expensive high-tech platforms, is undergoing a fundamental review. Amidst growing tensions in the Asia-Pacific region, Tokyo is beginning to look at the combat experience in Ukraine, where cheap drones have proven their ability to destroy equipment worth hundreds of times more.
Paradigm shift: from elite systems to mass drones
Japanese military analysts and the leadership of the Self-Defense Forces have concluded that the traditional approach to defense requires adjustment. The key factor influencing this decision has been the effectiveness of the Ukrainian experience in using FPV drones and other unmanned aerial vehicles. The ability of relatively simple and affordable devices to shoot down complex targets, such as Iranian "Shahed" kamikaze drones, or to hit armored vehicles, is forcing Tokyo to reconsider its priorities in arms procurement.
Previously, Japan focused on a small number of ultra-modern units. Now, the concept of mass application is taking center stage: a large number of cheap, fast-to-produce, and easily replaceable drones.
Investments and new projects
The Ministry of Defense of Japan has already begun the practical implementation of the new strategy. In particular, the ministry is working on the concept of mass deployment of drones to protect remote islands. One of the key projects is the development of the SHIELD system, designed to ensure the defense of peripheral territories.
Funding for these ambitious plans has already been allocated in the budget. For the 2026 fiscal year, 277.3 billion yen (approximately $1.7 billion USD) has been allocated specifically for the development of unmanned platforms and corresponding infrastructure.
Partnership with Ukraine
Despite the active development of its own technologies, Japan is considering the possibility of direct cooperation with Kyiv. According to Japanese media, Tokyo is studying options for purchasing Ukrainian combat drones that have already been tested in real combat conditions. Another possible scenario is the exchange of defense technologies, allowing Japanese engineers to adopt the experience of creating effective and cheap UAVs.
Interest in Ukrainian developments in the field of UAVs and electronic warfare (EW) systems is not limited to the Japanese. It is known that the United States is also negotiating with Ukraine regarding the testing and possible acquisition of similar systems.
Assessment of the Armed Forces of Ukraine's potential
International recognition of the effectiveness of the Ukrainian military machine is growing. US Secretary of State Marco Rubio, in his statement, emphasized that the Armed Forces of Ukraine, thanks to accumulated combat experience and support from allies, have become the most powerful army in Europe. Experts believe that the lessons of this war could fundamentally change the appearance not only of the Japanese, but also of other armies of the world in the future.
