J-Startup and Beyond

In 2022, Japan’s government unveiled an audacious plan: create 100,000 startups, attract ¥10 trillion in investment, and produce 100 unicorns — all by fiscal year 2027. Three years in, the numbers tell a story of genuine progress and stubborn gaps. Here’s an honest assessment of where things stand.

The Five-Year Plan at a Glance

The Startup Development Five-Year Plan, launched under Prime Minister Kishida’s “new capitalism” banner in November 2022, was Japan’s most ambitious entrepreneurship initiative ever. It identified three pillars: talent development, funding access, and regulatory reform — all aimed at transforming Japan from a startup laggard into a globally competitive ecosystem.

The flagship program backing this effort is J-Startup, run jointly by METI, JETRO, and NEDO since 2018. Selected companies receive mentorship, co-working space, overseas expansion support, and priority access to government procurement. In March 2025, METI added 31 new startups to the program, with regional variants like J-Startup KANSAI expanding the net further.

Progress Report: The Numbers

The startup count has grown roughly 1.5x — meaningful, but a long way from the 10x target. University-originated startups hit a record 5,074 in 2024, and the mentor program has already exceeded its annual target. But the headline numbers — unicorns and total investment — remain stubbornly behind.

What’s Actually Working

Tax Reform Is Moving the Needle

Japan has methodically overhauled its startup tax regime. The Angel Tax system now offers substantial deductions for individual investors in certified startups. Stock option rules were liberalized in 2024, tripling the tax-advantaged exercise price ceiling from ¥12 million to ¥36 million and letting certain startups delegate option issuance to the board for up to 15 years. Starting January 2026, a new carryback refund system will let angel investors deduct startup investments against prior-year capital gains — a significant incentive for serial investors.

Deep Tech Is Finding Its Voice

Japan’s emerging unicorns tell a revealing story. Unlike Silicon Valley’s consumer-internet dominance, Japan’s highest-valued startups cluster around deep technology:

• Sakana AI (est. 2023, valued at ~$2.6B) — Founded by former Google researchers, it builds foundation models using nature-inspired AI. Achieved unicorn status faster than any Japanese startup in history.
• Preferred Networks (est. 2014, ~$2B) — Deep learning and robotics for industrial applications, with partnerships across Toyota and FANUC.
• Spiber (est. 2007, ~$1.2B) — Structural protein materials that could replace petroleum-based plastics and animal fibers.
• Clean Planet (est. 2012, ~$1B) — Quantum hydrogen energy, a potential breakthrough in clean power generation.
• TBM (est. 2011, ~$1B) — LIMEX, a limestone-based alternative to paper and plastic.

This deep-tech bias is no accident. Japanese universities produce world-class materials science, robotics, and biotech research, and government programs have specifically channeled funding toward lab-to-market translation. Many of these startups are designed to be global-first — a marked shift from the domestically focused consumer apps of a decade ago.

Public Capital Is Filling Gaps

The Japan Investment Corporation (JIC) and its subsidiary JICV have become significant players, deploying public capital to fill late-stage funding gaps that private VCs avoid. The FY2025 budget allocated ¥80 billion through the Fiscal Investment and Loan Programme specifically for startup risk capital. A new ¥1 trillion AI-focused support package is expected to begin in fiscal 2026.

What’s Not Working

The Unicorn Gap Is Real

Japan has 11 to 15 unicorns, depending on the count. The target is 100 by FY2027. That’s not happening. For context, the United States produces roughly 50 new unicorns per quarter. China and India each have hundreds. Japan’s number has roughly doubled from its 2022 baseline — respectable growth, but nowhere near the exponential trajectory the plan envisioned.

Late-Stage Funding Remains Scarce

According to JIC’s 2025 H1 market update, H1 2025 startup fundraising totaled ¥373 billion — well short of the ¥1 trillion annual run rate needed to meet cumulative targets. More critically, investment is skewing toward later-stage, proven companies, creating a widening gap that leaves early-stage ventures underfunded. The average deal size is rising, but the median is not — a classic sign of capital concentration.

Management Talent Is the Bottleneck

The Japan Venture Capital Association has identified management talent acquisition as the single biggest constraint on startup growth. Japan’s risk-averse labor market still steers top graduates toward large corporations. While programs like the mentor network are helping, the cultural shift from “join a big company” to “build a company” remains incomplete.

“Big in Japan” Isn’t Enough

As Global Venturing noted, Japan still struggles to produce startups with genuine global ambitions. SmartHR dominates Japanese HR tech but has no international presence. Many J-Startup companies optimize for the domestic market first, and by the time they consider expansion, competitors in other markets have already scaled. The deep-tech cohort (Sakana AI, Spiber) is bucking this trend, but they remain exceptions.

How Japan Compares

Japan’s ecosystem is the third-largest in Asia by investment volume but punches well below its weight relative to GDP. South Korea, with roughly 40% of Japan’s economic output, has produced nearly twice as many unicorns.

What Global Partners Should Know

For international investors, corporate development teams, and potential partners, Japan’s startup ecosystem offers a distinct value proposition:

• Deep-tech differentiation — Japan’s startups are strongest where others are weakest: advanced materials, precision robotics, industrial AI, and quantum technologies. These are capital-intensive, hard-to-replicate moats.
• Government co-investment — Public funding through JIC, NEDO, and prefectural programs reduces downside risk. Tax incentives are increasingly generous for foreign as well as domestic investors.
• Corporate partnership culture — Japan’s startup ecosystem is deeply intertwined with large corporates. Toyota backs Preferred Networks; major banks invest in fintech startups. This creates revenue certainty that pure-play VC markets often lack.
• The succession catalyst — As established SMEs face founder retirements, a new wave of “startup-like” opportunities is emerging: acquiring legacy businesses with strong fundamentals and injecting modern technology and management.

The gap between Japan’s startup ambitions and reality is real — but so is the trajectory. The government has put serious money, policy reform, and institutional infrastructure behind its bet. Whether it hits the 100-unicorn moonshot matters less than whether it builds a self-sustaining ecosystem. Three years in, the foundations are taking shape.
