Helsing's way into Japan's arms market runs through Rakuten, not a defence prime

Helsing, the Munich firm that has become Europe's best-funded defence-AI company, has enlisted Japan's Rakuten to help broker the sale of its unmanned systems to Japan's Ground Self-Defence Forces [s1c1][s1c2]. The channel matters more than the product here: a company known for online shopping and mobile networks is the intermediary, not a traditional prime contractor [s1c2][s1c11].

At the centre of the effort is the HX-2, a compact AI-guided strike drone that Japan's military is putting through field trials scheduled to run until the end of September [s1c3]. Helsing also sells AI software for battlefield analysis, underwater surveillance and combat aircraft [s1c4].

Rakuten is positioning itself explicitly as a broker that can walk foreign defence startups through Japan's opaque procurement system, and it has run the play before, having helped the Ukrainian drone-software firm Swarmer show its technology to Japanese units [s1c5]. That makes at least two foreign defence firms routed through the same conglomerate [s1d1]. The value on offer is not engineering or manufacturing capacity, which is what a prime normally sells a foreign entrant. It is access, paperwork and the standing of a local name [s1c5][s1c6].

The demand side explains the timing. Japan is in the middle of its biggest military build-up in decades, driven by an increasingly assertive China and by a war in Ukraine that has reset assumptions about drones [s1c7]. It eased long-standing arms-export and procurement rules earlier this year, opening a market foreign weapons-makers could barely touch before, and Helsing is not the only firm circling it [s1c8]. Tokyo has committed to lifting defence spending toward levels not seen in the postwar era [s1c9].

For operators reading this as a go-to-market pattern, the interesting part is what the broker does not de-risk. Helsing was founded in 2021, raised billions this year, ranks among Europe's most valuable private tech firms and has become a primary supplier of drones to Ukraine with Berlin's backing [s1c10]. It is also the company whose HX-2 orders Ukraine paused earlier this year after technical problems in the field [s1c12]. Japan is trialling the same model that a customer already stopped buying over field performance [s1d2]. A conglomerate can get a foreign startup in front of the right units; it cannot make the hardware work in a trial.

The wider read is that the defence boom has pulled in financiers, cloud providers and consumer-tech names alongside the traditional primes [s1c11]. Helsing itself is expanding on several fronts at once, including an AI submarine and an alliance with Mistral on military AI [s1c13]. Selling into Asia extends that beyond NATO [s1c14].

What to watch: whether the trials convert into contracts at all, which is still unknown, and Japan remains a cautious buyer with a long procurement memory [s1c15]. Watch the end-of-September trial deadline and any published finding on HX-2 reliability, given the Ukrainian pause [s1c3][s1c12]. Watch also whether Rakuten signs a third and fourth foreign defence client, which would mark brokerage as a durable business line rather than opportunism [s1c5]. And watch whether other closed procurement markets start producing their own commercial fixers, because if this works, the cost of entry becomes a relationship rather than a joint venture with an incumbent.
