No War, No Weapons

Core business: While Hitachi has pivoted toward digital solutions, it remains a major industrial conglomerate that manufactures railway, energy, and industrial infrastructure often utilized by defense sectors, and it maintains historical ties to military-industrial contracts. Behavioral evidence: Hitachi Ltd. is actively engaged in defense-related contracts, though these appear to represent a small fraction of its total revenue. In January 2026, the Japanese Ministry of Defense certified 2.6 billion yen in funding for Hitachi as part of a larger Australian frigate construction project.

Additionally, in July 2025, Hitachi entered a multi-year production agreement with Huntington Ingalls Industries (HII) to provide REMUS 300 uncrewed undersea vehicles (SUUVs) to the Japanese military. These vehicles are widely used by NATO members and other nations for naval operations. Historically, Hitachi has maintained ties to military-adjacent sectors through its investments and subsidiaries. In 2005, its subsidiary Hitachi Software Engineering partnered with Magic Software Enterprises, which later maintained IT systems for the Israeli Military Police. The company also operates Hitachi Data Systems in Israel and has invested over $43 million in Israeli venture capital. Furthermore, Hitachi construction equipment has been documented in use at the Salit Quarry in the West Bank, providing materials for Israeli infrastructure projects including checkpoints and the separation wall. While Hitachi has joined Japan-EU defense industry collaboration initiatives as of April 2026, there is no evidence of board-level oversight specifically dedicated to limiting or disclosing defense exposure. Instead, defense activities are treated as part of its broader industrial and digital portfolio. Given the specific project funding amounts identified (e.g., 2.6 billion yen) relative to Hitachi's massive asset base ($110 billion), direct arms-related revenue is estimated to be well below 5%.
