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.
