Shibuya Bit Valley Strikes Back: Why Global Geniuses Are Choosing "Implementation Experience in Tokyo" and "Japanese Universities"
December 11, 2025
"Japan is a developing nation in startups"—this has long been the prevailing narrative.
Whether you look at the number of startups, investment amounts, or unicorns, Japan is overwhelmingly outpaced by Silicon Valley.
Looking only at the numbers, that's "half true."
However, in the late 2020s, a quiet yet undeniable "shift" is occurring worldwide.
Students from top universities in America and Europe—MIT, Harvard, Stanford, Oxford, ETH— are beginning to come to Japan "to gain experience in Tokyo."
Recruitment managers at Google, Meta, and NVIDIA say:
"Those with Tokyo experience demonstrate higher performance after joining our companies."
And an even more astonishing phenomenon is beginning.
Students from the world's top universities are now even considering attending Japan's top universities.
Now, "studying in Tokyo" is increasingly positioned as the strongest career strategy for young people worldwide. It is increasingly positioned as the strongest career strategy for young people worldwide. What lies behind this trend?
The key lies in the rise of the "Bit Valley" centered around Shibuya.
■ Outnumbered. Why the world's geniuses still choose Tokyo
First, let's compare.
Number of Startups
Silicon Valley: 40,000–50,000 companies
Japan: 3,000–4,000 companies
Shibuya: Approximately 1,000 companies
VC Investment Amount
Silicon Valley: ¥20–30 trillion
Japan: ¥1–2 trillion
Number of Unicorns
United States: 200–300 companies
Japan: Over 10 companies
──The numbers are overwhelming.
However, the assessment of young engineers and researchers in recent years is the opposite.
"Working in Tokyo for six months offers more growth than working in Europe for two years."
Why has this reversal occurred?
■ The Core of Bit Valley's Surge: The World-Shocking "Ultra-High-Density City × Implementation Speed"
① The World's Premier "Walkable Tech City"
Within a 4km radius spanning Shibuya, Ebisu, and Roppongi,
Google, Meta, Amazon, NVIDIA
Preferred Networks, SmartHR, freee
RIKEN AIP, and bases for the University of Tokyo and Tokyo University of Science (formerly Tokyo Institute of Technology)
Domestic startups, foreign VCs, CVCs
All within walking distance.
Students from MIT or ETH (Switzerland's top technical university, Eidgenössische Technische Hochschule Zürich / ETH Zurich) are amazed. "Tokyo is the only major city where you can visit 10 companies in a single day."
America is a car society; commutes over an hour are the norm.
Tokyo is a "growth city with zero travel costs."
② World-leading collaborative power between large corporations and startups
Japan's corporate culture may seem conservative at first glance, but it becomes a weapon in the AI era.
Toyota × PFN
FamilyMart × Telexistence
Sony × Robotics AI
A city where proof-of-concept → improvement → mass production cycles at the fastest pace.
This competitiveness can only be achieved in countries with "deep & developed industries."
③ Tokyo is the "World's Leading AI Demonstration City"
Autonomous Driving
Unmanned Stores
Cashless society
Logistics Robotics
Security AI
MIT students call Tokyo this.
"Tokyo is a living lab."
(Tokyo is a living laboratory)
④ Foreign startup talent surges in Shibuya
Indian AI Engineer
Israeli cyber companies
European AI students on short-term internships
Harvard and MIT students' practical training
In Shibuya, companies that operate entirely in English are not uncommon.
⑤ Japan has begun competing globally with "BtoB × DeepTech"
It cannot win in the American-style "app wars."
But Japan possesses world-class strengths.
Factory AI
Robotics
Medical AI
Semiconductor Equipment
Space Systems
Mobility
The future industries themselves are right here in Japan.
This is the magnetism drawing young people from around the world.
■ Companies Symbolizing Bit Valley
● Preferred Networks (PFN)
Collaborating with Toyota and Fanuc, it elevated factory robotics to a world-class level.
● GITAI (Roppongi)
Conducting proof-of-concept with NASA/JAXA. At the forefront of space robotics.
● SmartHR (Shibuya)
A unicorn candidate driving the digitalization of HR infrastructure.
● freee (Osaki)
Making accounting DX the standard for SMEs in Japan.
● Telexistence (Minato Ward（City）)
Realizing remote robotic merchandising at FamilyMart—making global headlines.
● Paidy (Harajuku)
A Japanese Fintech success story acquired by PayPal.
A cluster of companies winning globally through quality, not quantity, is gathering in Tokyo.
■ Another "Quiet Revolution" Happening Now
Top global university students are beginning to consider Japanese universities
Traditionally, studying abroad meant the US or UK.
But now, students from MIT, Stanford, and Cambridge are
are seriously considering studying at Japanese universities.
There are three reasons:
① Japanese universities are emerging as hubs for future industries
University of Tokyo: AI infrastructure, semiconductors, next-generation cloud
Institute of Science Tokyo（formerly Tokyo Institute of Technology）:
Robotics, Materials Science
Rapidly growing STEM capabilities
Kyoto University: Mathematics, Life Sciences
Keio KMD: HCI and AI Social Implementation
Japan offers the optimal environment for learning about "future industries."
② Tokyo itself is the ultimate "experimental environment"
For researchers and students,
-Rapid Proof-of-Concept Testing
-Safe
-Clock-like accuracy of rail infrastructure
-Abundant data for research and analysis
The world's best match between research and the city.
③ Global companies highly value "Tokyo experience"
Hiring managers at Google, Meta, and NVIDIA praise Tokyo-experienced professionals for their strong problem-solving skills.
As a result, top talent from around the world is gathering in Japan, increasing the likelihood of higher international rankings (QS/THE) for Japanese universities.
The main ranking indicators are
International student ratio
International Faculty Ratio
Employer Reputation
Industry Collaboration
All of these are factors currently surging in Japan.
Global talent comes to Japan → Japanese universities become stronger → More top global talent follows.
This positive cycle is beginning to take shape.
■ Key Strategies for Japan to Increase Unicorns
● ① Focus on becoming a DeepTech nation
Invest in areas that support the future of industries, not just apps.
● ② Cultivating a culture where large corporations become the "first customers"
Toyota, NTT, JR, and others are seriously advancing startup adoption.
● ③ Internationalizing Stock Option Taxation
This is key to attracting talent.
● ④ Establishing visas for foreign entrepreneurs and English-based administration
Toward cities where registration and tax payments can be done in English.
● ⑤ Platformizing Universities for Entrepreneurship
Establish an MIT-style model linking research and entrepreneurship.
■ Conclusion: Tokyo as the World's Third-Ranked Tech City—Its Future Has Already Begun
We cannot compete with the US in the sheer volume of startups.
However, Tokyo's unique competitive advantages—its AI implementation capabilities, urban density, large-corporation collaboration strength, and public safety—
are attracting young people from around the world.
Students from MIT, Harvard, and Oxford say:
"Studying in Tokyo dramatically boosts career value."
Moreover, the world's top talent is beginning to choose Japanese universities themselves.
This is boosting Japan's university rankings and
and holds the potential to propel Tokyo into the ranks of the "world's top three tech cities."
Japan is reemerging not as a nation of apps, but as a nation of implemented AI and DeepTech.
At the heart of this transformation lies Shibuya's "Bit Valley."
The future has already begun to unfold.
