Helsing, a Munich-based artificial intelligence startup founded just five years ago, is using an unlikely partner,Japan's Rakuten e-commerce conglomerate,to break into Asia's defense market with autonomous strike drones and battlefield AI software. The partnership signals how rapidly the global weapons industry is being reshaped by software-first startups, cloud providers, and consumer tech companies chasing a market suddenly flooded with government spending.

Why Is Japan Opening Its Defense Market Now?

Japan is in the middle of its largest military buildup in decades, driven by an increasingly assertive China and lessons from Ukraine's war that have rewritten assumptions about drones and autonomous systems. Tokyo has committed to lifting defense spending to levels not seen since the postwar era and eased its long-standing arms-export and procurement rules earlier this year, throwing open a market that foreign weapons makers could barely touch before.

This timing is deliberate. Every yen of Japan's expanded defense budget is a magnet for exactly the kind of autonomous, software-led equipment that the war in Ukraine has made fashionable. Helsing, which raised billions this year and ranks among Europe's most valuable private tech firms, is far from the only defense startup now circling the opportunity.

What Is Helsing Selling to Japan's Military?

At the center of Helsing's pitch to Japan is the HX-2, a compact AI-guided strike drone that Japan's Ground Self-Defence Forces is putting through field trials scheduled to run until the end of September. Alongside the drone, Helsing sells AI software for battlefield analysis, underwater surveillance, and combat aircraft,a software-first arsenal that has made it one of Europe's clearest bets that artificial intelligence belongs at the heart of modern defense.

Founded in 2021, Helsing has become a primary supplier of drones to Ukraine with Berlin's backing. The company's core pitch is that modern warfare is increasingly won by software and autonomy rather than sheer hardware alone. However, that reputation carries some risk. Earlier this year, Ukraine paused further orders of the HX-2 after technical problems in the field, a reminder that the distance between an impressive AI demo and a reliable battlefield weapon can be wide.

How Does Rakuten Help Helsing Navigate Japan's Defense Bureaucracy?

Rakuten, a name better known for e-commerce and mobile phones, is positioning itself as a broker that can walk foreign defense startups through Japan's notoriously opaque procurement system. In a market where the paperwork can be as formidable as the competition, a trusted local name is worth a great deal. Rakuten has done this before, having helped the Ukrainian drone-software firm Swarmer show its technology to Japanese military units.

This partnership reflects a broader trend reshaping the defense industry. Capital and engineers are pouring into anything that promises an edge on a modern battlefield, pulling in financiers, cloud providers, and consumer-tech names chasing a market suddenly awash with government money. A company built on online shopping and mobile networks recasting itself as a matchmaker for weapons startups is a measure of how far the defense boom has spread beyond traditional defense contractors.

What Are the Key Factors Driving This Defense Tech Expansion?

• Software-First Strategy: Helsing's pitch that autonomy and AI matter more than hardware alone has resonated with militaries rethinking doctrine after Ukraine's drone-heavy conflict.
• Market Liberalization: Japan's easing of arms-export and procurement rules earlier this year opened a previously closed market to foreign defense startups for the first time in decades.
• Rapid Company Growth: Founded only in 2021, Helsing raised billions this year and has become Europe's most valuable private defense AI firm, demonstrating investor appetite for autonomous weapons technology.
• Geopolitical Pressure: China's assertiveness and the Ukraine war have convinced Japan to commit to defense spending levels not seen since the postwar era, creating massive budget availability.

Helsing's expansion extends well beyond Japan. The company has been building an AI submarine, striking an alliance with Mistral on military AI, and casting itself as a pillar of Europe's scramble to rearm. Selling into Asia extends that ambition well beyond NATO and quietly turns a European champion into a would-be global arms supplier.

Whether the Rakuten partnership converts trials into contracts remains unknown, and Japan remains a cautious buyer with a long procurement memory. Japan's own trials, with another month left to run as of the source publication date, will be watched closely to see whether the HX-2 performs reliably in field conditions. But the very fact that a European AI startup barely five years old is testing strike drones for the Japanese army, with an e-commerce giant as its fixer, captures how fast the business of war is being remade and how eagerly its new players are rushing in.
