How to Choose a Startup to Join in Japan: An Evidence-Based Guide for Job Seekers

Before You Start: A Reality Check

If you have a strongly risk-averse personality, a startup may simply not be the right environment for you.

Let me also be clear about something: we, at Global Recruitment KK, don’t pretend to have the expertise to predict which startups will succeed or fail—whether in Japan or anywhere else. If you are looking for that level of advice or certainty, we suggest you consult with the experts in the field, although chances are that even seasoned investors struggle with it.

What we can do, however, is reduce uncertainty.

Joining a startup is, by nature, a risky decision. According to the U.S. Bureau of Labor Statistics, about 50% of new businesses fail within five years.

Japan, however, presents a very interesting contrast, that might come as surprise to many. According to data published by the Ministry of Economy, Trade and Industry (2017 White Paper on Small and Medium Enterprises in Japan), startup survival rates in Japan are significantly higher:

1 year: 95.3%
2 years: 91.5%
3 years: 88.1%
4 years: 84.8%
5 years: 81.7%

In other words, more than 8 out of 10 startups in Japan are still alive after 5 years.

When compared internationally (U.S., U.K., Germany, France), Japan shows consistently higher survival rates over time, although this also reflects structural differences such as slower growth and more conservative business strategies.

So yes—startups are risky. But in Japan, they are often less fragile, yet also less explosive.

That said, not all startups are equal.

Some operate in environments, industries, and structures that significantly increase their chances of success. As a job seeker, you may not be able to control outcomes—but you can absolutely improve your odds by doing proper due diligence before saying “yes.”

Step 1: Start With Yourself (Are You Even a Fit?)

Before evaluating the startup, evaluate yourself.

In recruitment, we get a very clear view of this. Some candidates walk into conversations with visible excitement when startups are mentioned—you can literally see it in their eyes. They are drawn to speed, ambiguity, ownership, and the desire to have their voice heard from day one.

Others, however, are the opposite. They may not explicitly say “I want to avoid startups,” but over time it becomes clear that they value stability, prefer structured environments, and are uncomfortable with uncertainty

Neither is right or wrong, but misalignment here is one of the most common reasons for early turnover.

Research from Harvard Business Review highlights that working in startups requires tolerance for ambiguity, willingness to take on undefined roles (and even wearing multiple hats), and comfort with risk.

A simple question you should ask yourself is “Do I want to build something uncertain, or operate something already working?”

A Quick Note on Startups in Japan

Japan’s startup ecosystem is unique.

High survival rates (higher than many people think, as seen above)
Fewer unicorns compared to the U.S. or China
Strong government push to increase startup activity

According to the International Monetary Fund, access to venture capital remains one of the key constraints in Japan’s startup ecosystem.

There is also a structural difference, most experts suggest. While in the U.S there is this grow fast → become a unicorn → IPO mindset, in Japan grow steadily → IPO earlier → scale later prevails.

This explains why Japan has fewer unicorns but still produces many stable, successful companies.

For job seekers, this is critical: You don’t need to join a “future unicorn” to make a good career decision in Japan.

Step 2: Evaluate the Startup (What Actually Matters)

The following factors are not exhaustive, but they cover the most meaningful indicators of a startup’s potential.

1. Technology and Market Potential

The McKinsey Global Institute has identified key characteristics of disruptive technologies:

high rate of technological change
broad scope of impact
large economic value

Examples include AI, IoT, biotech.

The takeaway is that startups operating in high-impact sectors benefit from structural tailwinds.

2. Intellectual Property (Patents)

Research shows a strong correlation between patents and startup success.

A European study found that startups with patents are 2.5–3.5 times more likely to succeed within 10 years

Practical takeaway:

Check whether the company owns patents (actually, this might be a clever question to ask during the interview process)
Ask about proprietary technology

3. Founder and Network Quality

A study published in Nature found that a startup’s network position is predictive of success.

In practical terms, a startup founded by someone with strong credentials—such as a senior or C-level background at a large Japanese company—is generally more likely to succeed than one founded by someone with limited experience or weaker professional networks.

The reason is because networks bring access to capital, talent and customers.

What to check:

Founder’s previous roles
Industry reputation
Connections to major firms or institutions

We would say, that’s the “other side” of doing your homework as a job applicant.

4. Financial Status (Runway Matters)

Startups need cash to survive. The key concept is runway; this is, how long the company can operate with current funds.

General guideline:

<12 months → high risk
18–24+ months → more stable

However, a low-funded startup with exceptional potential may still be worth the risk.

5. Traction (Reality vs Vision)

Many startups have great ideas—but only a few have real traction.

This might be more complicated (and unlikely your recruiter might know the details), but whenever possible, look for: paying customers, revenue growth, and user base.

Experts call it market validation, which is said to be one of the strongest indicators of future success.

6. External Validation (Investors, Partnerships)

Strong investors act as a quality signal.

Examples in Japan are SoftBank Vision Fund, JAFCO, Sumitomo Corporation Group, etc.

Who invests in a startup often matters as much as how much is invested. And this is information many startup companies are happy to release to recruiting agencies. Often times, you might even spot it in job descriptions.

A Brief Note on Unicorns (Use with Caution)

A “unicorn” is a private company valued at over $1 billion. Examples in Japan include Mercari, Preferred Networks, and SmartHR. However, unicorns are rare and many successful companies never become one. Japan is said to favor earlier IPOs instead.

In other words, a unicorn status is a signal of extreme growth—not a requirement for a successful career.

Additional Consideration: Access to Talent & Research

Historically, proximity to top universities has helped startups access to talent and good research.

In Japan, we have seen spinoffs from universities such as University of Tokyo and Kyoto University. Although remote work is changing this dynamic, it still matters—especially in deep-tech.

***

Choosing a startup is not about predicting the future. It is about making an informed bet.

Choose sectors with strong tailwinds
Look for patent(s) activity
Evaluate founders and networks
Understand financial reality
Look for real traction
And most importantly—know yourself

Because, in the end, the best startup for you is not necessarily the one that becomes a unicorn, but the one that aligns with your risk tolerance, learning goals, and long-term career strategy.
