Japanese Fintech: A Huge Market, but Cutting-Edge Tech Alone Is Not Enough

For successful international expansion, great software is no longer enough: you also need to understand local market dynamics. This was the focus of the business breakfast held in Tokyo at FINOLAB, the heart of Japanese innovation, which is celebrating its tenth anniversary this year. The event was prompted by the launch of Ergomania's latest and second comprehensive fintech publication, The Flavor of Fintech Asia. During the discussion, Makoto Shibata (FINOLAB), Raul Allikivi (GIGA), and Dr. András Rung (Ergomania) debated the differences between the Japanese and European fintech ecosystems, touching on everything from corporate culture to user experience.

Dr. András Rung, founder and CEO of Ergomania, kicked off the event by sharing the backstory of the publication. Research into international trends began about five or six years ago by examining the African market. The unexpectedly positive reception of the articles published on the company's blog at the time paved the way for the first volume presenting the European markets, and now the new book mapping the Asian continent, which the team has been working on for the past two years.

"The Turkish fintech market is entirely different from the Japanese one, even though Turkey is geographically part of Asia. We tried to make the selection of the examined countries as diverse as possible," András Rung noted. The book covers twelve countries from Turkey and Oman through India to Japan, showcasing local specificities through thirty in-depth interviews with bankers, designers, and fintech founders.

Through concrete case studies, the book proves that without understanding local user habits, even the best digital product can fail. As noted during the event, the publication also serves as a practical guide: if a European company plans to expand into Uzbekistan, for example, a preliminary UX-focused mapping of the market drastically reduces business risks.

Market Size and the Forced Global Focus

The sharpest contrast between the European and Japanese ecosystems stems from market size. Raul Allikivi, an Estonian who has lived in Japan since 2001 and leads GIGA, a company focusing on the financial integration of foreigners, knows both worlds inside out. With 125 million people, Japan is such a massive market that a startup can comfortably grow into a giant without ever crossing the border. Europe, on the other hand, is highly fragmented; even its largest economies are dwarfed by the Japanese market.

This difference fundamentally dictates corporate strategy. For a fintech launching in Europe's 1.3-million Estonian or 10-million Hungarian market, international expansion is not an option but a prerequisite for survival from day one, meaning products are immediately optimized for multiple languages and legal environments. Japanese companies, however, often tailor their software so heavily to specific domestic needs and regulations that they face severe hurdles during global expansion. The proven, locally optimized model simply cannot be transferred to other regions using a "copy-paste" method.

Since European companies are forced to expand anyway due to their narrow and fragmented domestic markets, Allikivi believes the obvious question is: why not head toward Asia? While Western startups traditionally look to the United States, the expert pointed out that the 21st century's economic boom is clearly happening in the East. He illustrated this with a fitting analogy: "When we look to the West, we only see our own shadow, because the sun rises in the East." Although Europe's Open Banking directives are more advanced and offer convenient "out-of-the-box" solutions, the Japanese market holds enormous untapped potential for those willing to understand the local rules and invest energy into negotiating with major banks one by one.

Japanese Banks and Endless Decision-Making

In Japan, cutting-edge tech alone won't guarantee success; understanding the local corporate culture is just as crucial. Makoto Shibata, Chief Community Officer at FINOLAB, who worked at the Mitsubishi UFJ (MUFG) financial group at the dawn of online banking in 1998, spoke about the frustrations foreign companies face in Tokyo. For B2B services, time-to-market is critical, but at Japanese financial institutions, this process can grind to a halt.

"It is often a grueling task to figure out who actually makes the final decision in a Japanese organization, and who is merely doing the planning," Shibata pointed out. Due to traditional, consensus-based decision-making (nemawashi), even the simplest approvals can drag on for months. Over the past decade, countless startups have burned through their capital while stuck in endless Proof of Concept (PoC) testing phases with major banks, without ever reaching actual deployment.

Slowly but surely, however, things are starting to change. Major financial institutions have realized that excessive caution hurts their competitiveness, making them increasingly open to rapid partnerships and startup acquisitions. For European companies, the takeaway is clear: in Japan, patience is not just a virtue, but an essential part of the business strategy. B2B partnerships and market entry must be planned in a way that allows the company enough time and financial reserves to wait out the slow, multi-stakeholder corporate approval chains.

When English isn't Enough, and Forms Become a Nightmare

Language barriers remain a major hurdle in both the B2B sector and the user experience. While an English menu is a given in Europe, most Japanese banks do not offer fully-fledged English online account opening even to expats living in the country. Often, only the welcome screen is translated, followed by an impenetrable Japanese maze, ultimately forcing the customer to visit a physical bank branch.

However, this is not just a translation issue, but a hard technological barrier. Raul Allikivi cited one of the most painful quirks of Japanese IT systems: many banking interfaces still require the use of specific Japanese character encodings ("half-width katakana" and "full-width romaji") in their web forms. For a foreigner used to seamless modern smartphone apps, registration turns into an instant nightmare when the backend system throws an error just for entering their own name.

While generative AI and modern translation tools now make it easier to understand web pages, trust is paramount in finance. A clumsily auto-translated banking interface instantly drives customers away. Localization, therefore, cannot stop at translating words: the entire interaction design and user flows must also be adapted to cultural expectations.

The Power of Cash and the ATM Renaissance

The greatest paradox of the Japanese financial world is the coexistence of high-tech and a massive reliance on cash. While physical banknotes are becoming a rarity in Scandinavia, the share of cashless transactions in Japan still sits below fifty percent. UX research also confirms this: for locals, physical tangibility still equates to reliability.

The massive networks operating in convenience stores essentially function as digital bank branches

Although the number of traditional bank branches is declining there too, services are often migrating not to mobile phones, but to ATMs. The massive networks operating in convenience stores (konbini), such as Seven Bank's 26,000-plus machines that already communicate in ten languages, essentially function as digital bank branches. At the same time, the enduring power of cash and physical presence is highlighted by a sight that is almost incomprehensible to European eyes: walking into a traditional Japanese bank branch to find ten ATMs lined up next to each other. Fintech companies must learn from this that when designing an omnichannel experience in Japan, the smart integration of physical ATM interfaces is just as important as a perfect mobile app.

Regulatory Innovation: Green Light for Stablecoins

Japan's legal environment moves slowly, but it is capable of proactive innovation when global trends demand it. The stablecoin market is the perfect example. Makoto Shibata highlighted that Japan was among the first in the world to establish a comprehensive regulatory framework in this area. JPYC, a FINOLAB member startup, received its license to issue a Japanese yen-based stablecoin after five years of struggle and over two years of tough legal negotiations.

Interestingly, the Japanese authorities' move was paradoxically spurred in part by a US regulatory draft; decision-makers realized that if they didn't act in time, they would fall behind. However, this type of innovation in Japan remains strictly permissioned, unlike the freewheeling European startup scene. New technologies must adapt to the existing system, involving traditional banks. In return, once legal hurdles are cleared, a massive, instantly scalable market opens up, which could radically reduce transaction costs for future payments.

Social Problems as the Engine of Fintech

Perhaps the most important takeaway from the discussion was that the Japanese fintech sector is no longer driven by technological feats, but by pressing national demographic crises. Makoto Shibata highlighted three main priorities: the aging society, the chaos caused by digital payments, and the mobilization of retail savings.

The aging population presents design challenges that Europe won't face for decades. The vast majority of Japanese banking wealth is held by the senior generation. However, the small print in online apps and the constant tech jargon alienate this wealthy demographic. Many banks even prohibit the purchase of securities for customers over 80, arguing that the elderly can no longer properly assess risks. In response, new AI-based cognitive tests have emerged to objectively measure the decision-making capabilities of seniors, restoring their financial autonomy.

In parallel, intergenerational wealth transfer poses a major challenge. It is a common phenomenon that when rural parents pass away, after the hefty Japanese inheritance tax is paid, the wealth flows to younger relatives living in cities, completely draining capital from rural regional banks.

Digital Chaos, Dormant Wealth, and the New Purchasing Power

Meanwhile, the spread of digital payments has created cognitive chaos: an average convenience store bombards shoppers with fifty to sixty different payment methods and loyalty programs. The winners of the future will be AI-driven smart wallets that seamlessly select the optimal payment method in the background.

The third priority mentioned by Shibata is channeling the massive retail savings sitting idle in banks into investments. Although the government tried to steer capital into the domestic market by expanding the NISA (tax-exempt investment account) scheme, a significant portion of the money ended up in US markets. To counter this, decision-makers have introduced new tax incentives and secondary markets for private shares to funnel savings toward the domestic startup ecosystem.

The other unavoidable aspect of these social challenges is the integration of foreign workers. As Raul Allikivi stressed, the Japanese economy would be dysfunctional today without foreigners. The number of foreign residents, currently comprising over two and a half million work permit holders and three million residents overall, is set to double in the next ten years. Traditional banks viewed this demographic as a risk for a long time, but today they recognize its growth potential. The mission of GIGA and similar fintech companies is to integrate this purchasing power into the financial bloodstream through modern services that are easily accessible in English.

Business Begins with Understanding

The conclusion of the Tokyo business breakfast is clear: the future of fintech lies in collaboration and solving real societal problems. As Makoto Shibata noted when summarizing FINOLAB's past ten years: while early fintech was mostly about increasing the efficiency of existing financial services and improving user interfaces, the startups leading the charge today are those offering solutions to Japan's deeply rooted social issues.

But why should a European company bother fighting in such an isolated market governed by unique rules, if the finished product is almost impossible to export directly to other countries later? The discussions at The Flavor of Fintech Asia book launch provided the answer. First, Japan is a demographic time machine. The country is currently battling the structural challenges, such as an aging society, generational wealth transfer, and digital payment chaos, that the Western world will only face in a decade or two. Whoever finds a working model here will be able to tackle future European challenges with an unassailable strategic advantage.

Second, the island nation is the ultimate stress test for digital product design. To succeed, companies must understand the local culture, legal environment, and genuine human needs so deeply that it elevates their adaptability to an entirely new level. Any company that manages to clear the linguistic, bureaucratic, and UX hurdles of the Japanese market gains a level of localization expertise that makes conquering any other market in the world feel like a routine operation.
