Huge swathes of money are flowing from Japan to European tech startups as risk-averse investors favor a more mature entrepreneurial ecosystem, helping to scale the continent’s booming deep tech cluster.
While the European startup and enterprise capital ecosystem has long operated within the shadow of Silicon Valley, it has turn out to be fertile ground for Japanese corporates, whose domestic market is younger. Â
Japanese investors or enterprise capital funds who themselves have Japanese investors, often called limited partners, participated in European financing rounds price greater than 33 billion euros ($38 billion) since 2019 when a trade deal between the European Union and Japan got here into force, in keeping with research from enterprise capital fund NordicNinja and data platform Dealroom. Â
For the five years leading as much as the EU-Japan Economic Partnership Agreement, investment totaled 5.3 billion euros.
In Europe at the moment, “there was no Japanese capital aside from Softbank,” Tomosaku Sohara, co-founder and managing Partner of Japan-Europe VC NordicNinja, told CNBC. NordicNinja, which has 250 million euros of assets under management, is a three way partnership between Japan’s JBIC IG Partners and personal equity firm BaltCap.
“Softbank was pretty energetic already at that moment, because that they had acquired Finnish gaming company Supercell,” Sohara said, noting that the acquisition injected life into Finland’s startup ecosystem.Â
Now, Mitsubishi, Sanden, Yamato Holdings, and Marunouchi Innovation Partners are amongst those directly backing European tech, per the report, while Japan-linked enterprise capital firms equivalent to NordicNinja, Byfounders, and Toyota‘s Woven Capital cut checks to startups on the continent.Â
There are over two times more VC-backed startups in Europe than in Japan, per capita, and 4.3 times more unicorns, per the report.Â
The shadow of Silicon Valley Â
Japan’s appetite for investing was all the time there, Sohara said. Its multinationals — like many — headed stateside to establish corporate enterprise capital arms in early 2000, searching for a slice of the motion on the time when a few of today’s largest firms were just being thought up in dorm rooms. Â
“No one wanted to have a look at Europe at that moment, but I feel that after a few years they realized, ‘Hey, perhaps the U.S. culture is completely different from the Japanese culture,’ and so they began pondering, ‘Hey, perhaps we want to have a look at one other region like Europe,'” Sohara said, adding that the profile of entrepreneurs in Europe, lots of whom got here from large corporates on the time, was more aligned with Japan. That is in contrast to the young founders coming from Stanford or university research and development departments, he said.
“They’ve experience on the corporates and in addition they’ve a mindset of entrepreneurship. Japan, unfortunately, is lacking the entrepreneurship mindset,” Sohara added, referring to Europe’s founders, lots of whom got here from Nokia and Skype.
The pull for founders
Japanese-linked investors have a penchant for one sector specifically: deep tech, which refers to firms constructing on top of scientific or engineering innovation. Deep tech and artificial intelligence accounted for 70% of deals made by such investors in Europe in 2024, echoing trends within the broader startup ecosystem because the AI, energy, and defense industries boom. Â
The highest-funded firms with Japanese participation include the U.K.’s autonomous vehicle startup Wayve, which raised $1.05 billion in an investment round in May 2024, British quantum computing firm Quantinuum, which secured 273 million euros in January 2024, and Spanish quantum firm Multiverse Computing, which saw investors cut it a check of 189 million euros in June 2025. The rounds were backed by Softbank, Mitsui and Toshiba, respectively. Â
Such firms, nevertheless, typically need lots of growth capital and industrial experience to scale successfully — two elements that Europe famously lacks. Â
“Investment appetite is way stronger than [in] any strategics I’ve seen here in Germany or in Europe,”
Sarah Fleischer
co-founder and CEO, Tozero
“Japanese firms — and so they’re old, most of them that we’re talking about, right — they’re just sitting on a pile of cash. They have been saving money throughout the last century, and now they’re beginning to spend it, to attempt to grow as a big corporate and increase their footprint outside of Japan,” said Sarah Fleischer, co-founder and CEO of Germany-based battery materials recycling startup Tozero.Â
“You see that investment appetite is way stronger than [in] any strategics I’ve seen here in Germany or in Europe,” she added. Tozero has raised 14.5 million euros up to now and counts NordicNinja, Honda and JJC amongst its investors.
It is not just in regards to the check. Japanese corporates and industrials have robust manufacturing and automotive know-how, Fleischer and Sohara noted respectively, meaning they’re well positioned to plug Europe’s knowledge gaps in terms of scaling large manufacturing projects.
Fleischer added that Japanese firms have long shored up their critical minerals supply chain and long-established trading firms, meaning they know the way to secure essential components needed for the energy transition. For Tozero, that is an added plus, Fleischer said, given it’s within the business of recovering such materials from spent batteries.Â
Within the age of political uncertainty amid choppy U.S.-China relations, Japan also acts as a superb bridge to the Asian markets, Fleischer said.
A slower pace and lower risk appetite
Back in Japan, the variety of entrepreneurs is “still very limited,” Sohara said, because the older generation and “great talents” desired to work for “a Toyota and Honda or Sony,” he added, however the younger generation’s mindset is starting to alter. Â
Europe has also turn out to be the house to ambitious would-be founders trying to find a tech ecosystem to construct their firms in, Sohara said.
Nevertheless, as collaboration between Europe and Japan scales, language stays a barrier as fluency in English just isn’t widespread in Japan, he added. Â
For Fleischer, this also poses challenges. “There’s a lot miscommunication and native translation that would damage a partnership immediately. And there is also some kind of cultural aspect as well, one must probably pay attention to,” she said, adding that she recently spent weeks in Japan attending to know her investors face-to-face, “because that is still the sentiment” there. Â
Decision-making can subsequently be slower, the founder said, as a result of thorough research and preparation. “They simply do their homework,” Fleischer said, noting that Japanese partners were hands-on in helping the corporate understand “the way to construct our next future business plant, potentially ranging from Japan after which going worldwide.”

Indeed, “without the support from NN [NordicNinja] it might have been rather more difficult to construct the proper relationships,” said Aaike van Vugt, co-founder and CEO of Dutch nanotechnology engineering firm VSParticle.
That is in contrast to perhaps probably the most well-known Japanese player: Softbank. Softbank is “totally different” from traditional Japanese investor cultures, given it’s driven by founder Masayoshi Son’s decisions somewhat than operating on a consensus basis, like most Japanese business, Sohara added. Â
The enterprise firm, known for its lofty bets on WeWork and, more recently, chip company Arm, poured huge sums of money into tech startups amid the 2021 enterprise capital tech boom, which saw no less than one Japanese-linked investor involved in deals price 11.2 billion euros, per the report. Softbank stood out during this era; it was involved in 22% of deals with Japanese-linked participation in 2021.
Interest ticking up
Looking forward, Sohara and Fleischer expect greater collaboration between Europe and Japan. Nevertheless, Japanese investors are expected to take part in rounds price 3 billion euros in 2025, per the Dealroom and NordicNinja report, representing a dip from last yr. Â
“I feel it is also politically driven as well in Japan, by the federal government, to position themselves more geopolitically smartly and be sure that that the corporates or the industries grow in certain ecosystems, strengthening their positioning as a rustic,” she said. Â
