Japan is stepping up drone cooperation with Ukraine to develop its own unmanned forces from Kyiv's wartime experience, and the two are building a joint drone cluster, the South China Morning Post reported. The centerpiece is a planned Japan-Ukraine Drone Cluster linking the two countries' industries. The drones are meant for Japan's defense against Russia and China, not for Ukraine.

Inside the cluster

The proposed cluster would unite Japanese manufacturers with Ukrainian defense firms, research centers, universities, and technology companies, the South China Morning Post says. Japanese companies are also working with European partners on anti-submarine drones.

Masayuki Masuda, who heads Chinese studies at Japan's National Institute for Defense Studies, the Defense Ministry's think tank, said the world has watched warfare change since Russia's invasion, and that drones will carry "much of the fighting on the future battlefield." He credited Ukraine's strong performance largely to drones.

Masuda argued that quantity now matters as much as quality. Japan's many small firms, he said, could quickly turn out cheap drones in the numbers a war might demand.

A defense turn

The cooperation is part of a wider overhaul of Japan's defense policy. In May, Tokyo sent Self-Defense Force officers to NATO's mission headquarters in Germany for the first time—to a facility that coordinates weapons deliveries and training for Ukraine. Japan also joined the Prioritized Ukraine Requirements List (PURL), the program through which allies fund US weapons for Ukraine, including Patriots. Japan, however, pledged funds only for buying non-lethal equipment from the US.

The drive is not only about Russia's war. It is also a response to China's growing military activity, with Tokyo tracking Chinese drones near the disputed Senkaku Islands, close to Taiwan, and across the South China Sea.

Ukrainian defense manufacturer AIDronesUA and Swedish technology firm Njord Technology AB have signed a Memorandum of Strategic Partnership at the Eurosatory-2026 defense exhibition in Paris, per Oboronka. The partnership scales production of the MAUL casualty evacuation, logistics, and ammunition delivery platform in Sweden. 

The MAUL ground robot costs between $22,600 and $33,900 per unit, depending on the communication configuration. AIDronesUA says that MAUL was developed and continuously refined based on real combat experience and direct feedback from Ukrainian soldiers operating the platform on the frontline.

"Together with Njord Technology AB, we plan to organize joint production of UGV MAUL on Swedish territory, which will allow expanding production capabilities and accelerating delivery of robotic systems," AIDronesUA says.

The Ukrainian company emphasizes that its priority remains meeting the needs of the Ukrainian Defense Forces, with most of the produced complexes intended for logistics, casualty evacuation, and the preservation of Ukrainian soldiers' lives. 

Njord Technology brings Swedish engineering to Ukrainian battlefield experience

"The combination of Ukrainian practical experience and Swedish engineering expertise will create modern robotic solutions that improve task performance and help save lives," Njord Technology notes.

This partnership will also foster industrial cooperation between Sweden and Ukraine and create new opportunities for technological development and innovation, the company said. 

The Swedish company creates autonomous solutions and AI systems, and is a member of the Swedish Security and Defense Industry Association (SOFF). The partnership joins a growing list of Swedish-Ukrainian defense industry agreements, including the Saab-Radionix sensor and defense electronics memorandum and ongoing discussions regarding potential Gripen fighter aircraft supply.

Ground robotic systems lead Ukrainian defense innovation

Ground robotic systems have become one of the most active categories of Ukrainian defense industry expansion. Ukraine ordered 25,000 ground robots for H1 2026 procurement, which is more than double the 2025 total.

Defense Minister Mykhailo Fedorov reported in March 2026 that Ukrainian ground robotics manufacturers had grown from zero to more than 100 since the start of the full-scale aggression.
