U.S. and Japan deepen tech & defense ties
Leaders from the U.S. and Japan unveiled new energy, defense and tech initiatives to strengthen deterrence in the Indo‑Pacific, including joint investment and market access measures aimed at critical minerals and defense tech. The package signals expanded bilateral pathways for robotics and embedded systems collaboration and supply‑chain alignment. ( )
On March 19, 2026 the United States and Japan published a U.S.–Japan Action Plan on Critical Minerals that explicitly directs the two governments to develop coordinated trade policies and border mechanisms — including exploring “border‑adjusted price floors” for a select group of minerals. (ustr.gov) The summit package also included a memorandum of cooperation to share deep‑sea mineral science and projects, with Japanese presentations on rare‑earth “mud” near Minamitorishima and plans for U.S.–Japan working groups on seabed resource development. (asahi.com) A White House fact sheet tied specific industrial commitments to the deal, naming up to $30 billion with Mitsubishi Electric for data‑center power systems, $25 billion with TDK for advanced electronic components, $20 billion with Fujikura for optical fiber, $15 billion with Murata to produce multilayer ceramic capacitors and related parts, and $15 billion with Panasonic for energy‑storage and electronic devices. (whitehouse.gov) That same White House documentation lists “up to $332 billion” in Japanese commitments to critical energy infrastructure projects — including SMR and AP1000 reactor work with Westinghouse and SMR collaboration with GE Vernova and Hitachi — moves that were framed as supporting data‑center and industrial power needs. (whitehouse.gov) Analysts and defense observers said the agreements establish new institutional pathways for cooperative defense acquisition and industrial coordination, including discussion of a Defense Industrial Cooperation, Acquisition, and Sustainment (DICAS)‑style forum to align procurement and sustainment priorities. (csis.org) Tokyo’s domestic steps to enable closer tech transfer — a new security‑clearance system and plans for a Defense Innovation Technology Institute modeled on U.S. innovation units — were cited as complementary moves that make tighter U.S.–Japan integration on uncrewed systems and other defense‑grade embedded technologies more practicable. (nationaldefensemagazine.org) The public papers explicitly tie critical‑minerals work to downstream products used in robotics and embedded systems — naming permanent magnets, batteries, catalysts and optical materials as targeted derivatives — signaling a policy push to secure inputs for motors, power electronics and sensors used in humanoids, drones and industrial robots. (gallery.modernengineeringmarvels.com) Japanese commercial tech firms are already in the U.S. defense innovation pipeline, with EdgeCortix winning a U.S. Defense Innovation Unit contract for edge AI hardware and software in 2025 — a concrete example of how the government‑level framework is intersecting with embedded‑AI suppliers.
