![Solving Social Issues Is the Largest Business Opportunity: SusHi Tech's Real-World Examples of "Pain-Point-First Management" [SusHi Tech Tokyo 2026]](/images/columns/solving-social-issues-business-opportunity-2026/cover.png)
Hello, this is Hamamoto from TIMEWELL. "I come from the world's happiest capital, in the world's happiest country." The moment Helsinki's Mayor Daniel Sazonov introduced himself with a smile, the room relaxed into a warm atmosphere. Yet over the next hour, I came to realize that this keyword — "world's happiest" — was not merely a tourism pitch. It was, in fact, a metric pointing to the very essence of a startup ecosystem.
At SusHi Tech Tokyo 2026, the session "Solving the World's Social Issues is a New Business Opportunity" was held as part of GNETs (Global Network of Tokyo Summit). Tokyo was selected as the venue for the third mayoral-level summit of this international city network, which connects more than 50 cities worldwide[^1].
In this report, I want to lay out the contours of "pain-point-first management" as presented by a remarkable lineup — Helsinki, Espoo, Tokyo, and NEC — along with the energy I picked up from the room. Almost without us noticing, social issues are being redefined: they are moving out of the philanthropic domain and into the territory of the largest business opportunities.
About the Event — How GNETs Co-Hosting Has Evolved SusHi Tech
SusHi Tech Tokyo 2026 is one of Asia's largest global innovation conferences, held at Tokyo Big Sight from April 27 to 29, 2026. A record-breaking 770 startups are participating, but the most significant feature this year is the co-hosting of the GNETs mayoral summit[^4].
GNETs is an international network in which urban leaders share knowledge and technology toward solving urban issues. By layering a city-diplomacy dimension on top of a traditional startup conference, SusHi Tech has evolved from one of Asia's largest innovation hubs into an international urban policy platform.
For our coverage of the keynotes — including the "Startup Nation Japan" vision and its three pillars — see our separate piece, SusHi Tech Keynote Report. In this article, I want to zoom in on what hangs off that backbone: the "concrete policy in the field," which is to say, what it actually looks like when cities collaborate on social issues.
Helsinki — 1,500 Startups in a City of 700,000
The numbers Mayor Sazonov shared were striking. Helsinki has more than 1,500 startups (840 in early-stage), more than 22,000 employees, over $35 million in R&D investment, $7.1 billion in annual revenue — and a city population of 700,000[^2].
1,500 startups for a city of 700,000 people. That puts the per-capita startup density among the highest in the world. If you do a simple comparison of Helsinki's population density and entrepreneurial density, for Tokyo to match on "startups per capita," the metropolis alone would need tens of thousands of startups.
| Metric | Helsinki | Tokyo (for scale comparison) |
|---|---|---|
| Population | ~700,000 | ~14 million (metropolitan) |
| Number of startups | 1,500+ (840 early-stage) | Aiming for an agglomeration on the order of tens of thousands |
| R&D investment | $35M+ | At scale, partnership with large enterprises is essential |
| Annual revenue scale | $7.1B | Leading on industrial agglomeration; needs to catch up on density |
The event that has come to symbolize Helsinki is Slush. Fund representatives commanding more than €4 trillion attend, alongside more than 300 affiliated events. This is no longer just an event for one city — it functions as the hub of the European startup ecosystem as a whole. Slush started as a student-led initiative, but it has grown into a destination that VCs from around the world commit to visiting "once a year, no exceptions." It is one of the North Stars SusHi Tech can aim toward.

Mayor Sazonov's Core Argument — "Quality of Life Is the Foundation of the Ecosystem"
What Mayor Sazonov emphasized again and again was the quality of citizens' daily lives as the foundation of an entrepreneurial ecosystem. Political stability, low corruption, advanced transparency, robust education, a strong ICT talent pool, gender equality, a safe and reliable welfare system, and work-life balance. He listed all of these.
At first glance, none of this looks related to startups. But the logic Sazonov laid out was clean: "Entrepreneurial spirit can only blossom when there is a foundation of daily life that lets people focus on creative work."
For Tokyo, this is an extremely important suggestion. Japan possesses world-class public safety, healthcare, and infrastructure. At the same time, it carries structural challenges — long working hours, gender gaps, and slow responses to aging. The framing that "quality of life" is itself one of the metrics of a startup ecosystem is, I believe, a perspective that should be installed into Tokyo's urban policy.
Measuring innovation capacity solely by the number of venture capital firms or total funding raised is one-dimensional. An environment in which founders, employees, and their families feel safe enough to keep taking on long-horizon challenges is what produces agglomeration ten or twenty years later. Listening to this discussion at SusHi Tech, I was struck by how the root is the same as what TIMEWELL routinely proposes to clients — "redesigning ways of working" and "building knowledge environments."
Espoo — A City That Ranks Second in the World in Quantum Technology
Next up was Jaana Tuomi, CEO of Espoo, whose talk crystallized the concept of "the city as enabler."
Espoo is Finland's second-largest city, located 10 minutes from Helsinki. The numbers are remarkable. It is the fastest-growing city in the Nordic region; ranks fourth in Europe in applied patents; sees more than 100 new startups founded each year; hosts more than 1,000 high-tech companies; ranks second in the world in its quantum technology ecosystem (Cambridge holds the top spot); and has cut CO2 emissions by 64% from 1990 levels (with a 2030 carbon-neutral target)[^3].
Espoo is home to clustered startups occupying globally dominant positions: IQM (a world-leading quantum computing company) and ICEYE (operator of the world's largest SAR satellite constellation), among others. The fact that "a city of 300,000 can build clustering at this level" demonstrates that city size and innovation density are not necessarily proportional.
In Japan, "correcting Tokyo-centric concentration" often surfaces as a topic of debate. But looking at the cases of Helsinki and Espoo, the conversation needs to go one layer deeper. It's not "scale," it's "design" — what combination of universities, government, and private sector, focused on what theme, drives concentrated investment? Espoo focused on quantum technology and satellites and reached the top of the world in both. In Japan too, a strategy in which a regional city goes deep on a single world-class theme is genuinely viable.
Espoo's Success Factor — "Radical Multidisciplinary Collaboration"
The success factor Tuomi cited was the concept of "Radical Multidisciplinary Collaboration." A model in which academia (Aalto University, the VTT Technical Research Centre), private enterprise, and the public sector function as an integrated whole, oriented toward the same goal.
The most symbolic example is the Microsoft × Fortum joint project. It uses waste heat from a new data center to cover roughly 40% of Espoo's district heating. Data centers are facilities that consume enormous amounts of energy by nature, but here that waste heat is being repurposed for residential heating. Profit-seeking activity by a private enterprise translates directly into improvements in citizens' quality of life — this kind of integrated design is the essence of a circular economy.
Tuomi emphasized: "Espoo's success is not based on any single company, any single university, or any single policy — it is based on collaboration across all of them."[^3]
This brings to mind the data center debate of the AI era. In Japan as well, energy consumption is becoming a serious headache, but Espoo converted "waste heat" — a liability — into "a heating resource" — an asset. By abstracting the framing of the problem one level higher, a pain point becomes a business opportunity. This kind of design capability is, I believe, the heart of the social-issue-driven business model.
Tokyo's "T 10x10x10 Innovation Vision"
Sheena Iwai, Senior Director of Tokyo's Startup Strategy Promotion Headquarters, presented the "Tokyo T 10x10x10 Innovation Vision" — a clear numerical target.
Over five years, increase startups, unicorns, and public-private partnerships each by tenfold.[^4]
Ambitious — but not impossible. SusHi Tech Tokyo has already established itself as Asia's largest innovation conference (now in its fourth year), recording more than 410,000 visitors per month. Tokyo Innovation Base (TIB) has been visited by figures including French President Macron, and is becoming a global hub.
Under the new strategy, "Global Innovation Strategy 2.0," three projects are being driven forward: "Sustain-Tech Global," "TIB Incubate," and "City Solution Project." In particular, through partnerships with GNETs member cities, the conditions for Tokyo-based startups to tackle international challenges are being put in place.
| Project | Overview | How to Read It as an Executive |
|---|---|---|
| Sustain-Tech Global | Support for international expansion of sustainability-focused ventures | Designed around the assumption that you go to market together with overseas regulations and subsidies |
| TIB Incubate | Incubation centered on TIB | The phase where the "network," not the "physical building," becomes the real product |
| City Solution Project | Pilot collaborations with GNETs cities | Not single-company sales, but a "city × company" sales motion as the mainstream |
The shift from "going global as a single company" to "going global on top of a city platform" carries real implications for mid-sized companies as well. For many Japanese companies that have struggled with overseas expansion, city platforms can also function as a new distribution channel.
NEC's Matsuda — A Concrete Case in International Collaboration on Plastic Waste
The case of "plastic waste reduction" presented by Mr. Matsuda from NEC's Business Innovation Division was a deeply useful concrete example of private × public × international collaboration.
The numbers are sobering. In Japan, 9.1 million tons of plastic are disposed of every year, and the recycling rate sits at just 22%[^5]. The biggest problem is the lack of standardized data and the difficulty of information sharing. Recycled-plastic manufacturers, plastic-using corporations, retailers, and logistics providers — there are simply too many stakeholders, and the information does not connect across them.
Through its "Global City Tech Beach" program, NEC is collaborating with startups to build a data platform that links these players. "Use data to connect industries" — a quintessentially NEC approach.
Challenges that cut across supply chains all share a similar structure. "Local optimization has been pushed about as far as it can go — what's missing is the data foundation for global optimization." This is the same structural pattern across many domains: food loss, supporting the daily lives of foreign workers, information delivery during disasters, regional healthcare. Precisely for that reason, providers capable of designing a data-linkage platform are looking at a massive market for the foreseeable future.
Matsuda's Core Argument — "The Cultural Gap Is the Largest Barrier"
The line Matsuda delivered was the sharpest of the entire panel.
"The cultural gap between large enterprises and startups is bigger than language and cultural differences."[^5]
For anyone working on the ground in international collaboration, this is a truth you can't help but nod at. Language barriers can be handled with interpreters. Cultural differences can be learned over time. But "the sense of time horizons," "the speed of decision-making," and "the attitude toward failure" are inscribed into an organization's DNA — and that makes them extraordinarily hard to change.
To clear this barrier, Matsuda pointed out, the keys are "bidirectional benefits" and "contributing not just usage of the technology but actual revenue." A posture in which the large enterprise is "doing the startup a favor by using their technology" is not sustainable. A frame of equal value exchange is what is needed.
At TIMEWELL we support many situations in which corporate intrapreneurs partner with startups, and the hardest part is always how to design the "equal value exchange." Capital, data, distribution networks, brand — large enterprises have many resources to offer, but whether those resources have been broken down into "units a startup can actually use" is a separate question. We are entering a phase in which large enterprises need internal "translators to the startup world" as a distinct talent profile.
Author's Reflections — The Era of "City-Led Innovation Diplomacy"
What I felt most strongly through this session is that "cities, not nation-states, are becoming the protagonists of innovation diplomacy."
Helsinki's mayor, Espoo's CEO, Tokyo's metropolitan government — they are no longer bound to their national governments and are connecting directly with one another. The GNETs framework is, I believe, a new form of "city diplomacy", and its importance will only grow.
For Japan, this is an extremely positive signal. Without being constrained by the speed of national-level decision-making, the Tokyo metropolitan government can independently partner with Finnish cities. Startup visas, data linkage, joint pilot projects — these concrete policies can be advanced without waiting on bilateral treaties.
From the perspective of a business executive, this represents a new "precondition for business expansion." Until now, the dominant route was the linear one: "win in Japan first, then expand overseas." But once you can use city platforms, the option to run Tokyo, Helsinki, Singapore, and London in parallel becomes a realistic choice.
What It Will Take to Realize "Radical Multidisciplinary Collaboration" in Tokyo
What will it take to realize Tuomi's "Radical Multidisciplinary Collaboration" in Tokyo? In my view, four things:
- Shared KPIs across large enterprises, universities, local governments, and startups
- Physical shared spaces (extensions of TIB, fingate, and similar)
- A new legal framework for IP and data sharing
- The cultivation of a culture that tolerates failure
The most important is point 1, shared KPIs. Today, each player chases a different number — revenue, paper count, policy outcomes, jobs created — so the sense of being "in the same boat" never develops. If a framework like GNETs can establish "city-level social-issue KPIs" that are shared across players, the foundation for radical multidisciplinary collaboration falls into place all at once.
The intrapreneurs TIMEWELL supports are exactly this kind of "boundary-crossing" presence. From inside large enterprises, they move like startups and partner with universities and local governments. As boundary-crossing talent grows, Tokyo's "Radical Collaboration" accelerates.
Cities Need "the Courage to Relinquish Control"
Another striking line from Mayor Sazonov was: "Cities need the courage to relinquish control."
Within regulatory bounds, grant trust and degrees of freedom to startups. For an administrative organization, this is an extraordinarily difficult choice. If something fails, accountability comes back. But excessive control kills innovation. Behind Helsinki and Espoo's global startup successes lies the courage to let go, in measured doses.
The Tokyo metropolitan government has begun to display this courage too, but I'd say we are still mid-journey. "A city's tolerance for failure" is something that will need to be raised further. The same structure applies inside large enterprises pursuing internal new-business initiatives. Holding all decision-making authority while telling people to "go run free" is not a recipe for innovation. The combination of delegated authority and well-designed KPIs is the foundation that continuously produces social-issue-driven businesses.
For another angle on the culture-meets-technology conversation, I've also covered the Kabuki × entertainment-tech session. Reading the "short-term pain points" of social issues alongside the "long-term pain points" of traditional performing arts brings the territory of challenge into much sharper, three-dimensional focus.
Conclusion — The Era When Cities and Startups Together Solve Social Issues
Solving social issues is no longer philanthropy. It is a massive business opportunity. And the model best positioned to capture that opportunity is the city × startup collaboration model.
Helsinki, on a foundation of quality of life and startup density. Espoo, on multidisciplinary collaboration and quantum technology. Tokyo, on scale and market size. Each leverages a distinctive strength while connecting through a shared platform called GNETs. This structure is set to be a decisive factor in the next decade of global urban competition.
What I want to underline as a CEO is that "pain-point-first management" is open to small and medium-sized companies as well. Even if you cannot match large enterprises on capital raised or technical resources, identifying the pain happening in the field faster than anyone, and validating it more doggedly than anyone is something you can do regardless of company size. In fact, when it comes to the speed of change, small and mid-sized companies and startups have an overwhelming advantage.
At TIMEWELL, we want to strengthen our role as a connector — bringing Japan's challengers into the global urban ecosystem. A future in which a Tokyo-born startup solves a Helsinki social issue, partners with Espoo's quantum technology, and expands into Singapore and London — that future has already begun. SusHi Tech Tokyo 2026, I felt strongly during that one hour in the venue, will be remembered as a place that clearly marks the beginning.
If you are a CEO or business leader who wants to sharpen an internal new-business initiative through a "pain-point-first" lens, or design an overseas expansion scenario that rides on global city platforms, please feel free to reach out.
