Key Takeaways
- Japanese startups largely operate outside seniority, cohort hiring and the traditional career structure.
- Many are more open to foreign professionals and to English as a working language than established firms.
- Stock options exist but the ecosystem is smaller and exits are fewer, so treat equity cautiously.
- Visa sponsorship is possible but depends on the company's stability and paperwork capacity.
- The scene is concentrated in Tokyo, with genuine but smaller activity elsewhere.
Japanese startups are the part of the market where most of the conventions covered elsewhere in this series simply do not apply. No shukatsu cycle, no nenko seniority, no cohort identity, frequently no requirement that you speak Japanese to native standard.
For foreign professionals that combination is genuinely attractive. The trade-offs are the ones startups carry everywhere, plus a few specific to Japan.
This guide covers what the scene looks like, how equity works here, and what to check.

What is different from established companies
No seniority system. Pay and progression follow contribution rather than years, which removes the mid-career disadvantage described in nenko seniority explained.
No cohort hiring. Everyone is a mid-career hire in effect, which removes the graduate-cohort ceiling that exists at traditional firms — see new grad vs mid-career hiring.
Language flexibility. Many startups operate substantially in English, particularly those with international investors or global ambitions. Some are fully Japanese-operating, so it varies sharply — check before applying rather than assuming, and see the JLPT for jobs guide.
Faster hiring. Weeks rather than months, and less formal than the tenshoku process — see the Japan job change tenshoku guide.
Broader scope. You will do things beyond your title, earlier than at an established company.
Less structure. No extensive training, less documented process, and considerably more ambiguity.
Equity, honestly
Stock options exist in Japanese startups, and they warrant more caution than in larger ecosystems.
The ecosystem is smaller. Fewer companies reach an exit, the venture market is less deep than the US, and secondary markets for private shares are limited.
Which means: treat options as a lottery ticket with lower odds than the equivalent in a larger market, not as compensation. If the cash salary is not acceptable on its own, the offer is not acceptable.
Questions worth asking, and a company that will not answer them is telling you something:
- What percentage of the company do the options represent, not just the share count?
- What is the strike price, and what was the last round's valuation?
- What is the vesting schedule and cliff?
- What happens if I leave — what is the exercise window?
- How much runway is there currently?
Tax treatment of options in Japan is its own subject and depends on the scheme structure. Get advice before assuming what an exercise would cost you.
The general framework applies as in startup vs big tech.
Why the share count on its own is meaningless
"We're offering you 10,000 shares" sounds substantial and tells you nothing at all. These three numbers together are what determine whether the grant is worth anything.
| What you need | Why | If they will not say |
|---|---|---|
| Total shares outstanding | 10,000 of 1,000,000 is 1%. 10,000 of 100,000,000 is nothing | Treat the grant as worth zero |
| Strike price | What you pay to exercise. A high strike on a flat company is worthless | Same |
| Last round valuation and date | Lets you value your percentage, and shows whether it is stale | Ask when they last raised |
| Vesting schedule and cliff | Typically four years with a one-year cliff — leave before it and you get nothing | Assume the worst |
| Exercise window after leaving | Frequently 90 days. If you cannot afford the strike then, the options vanish | This is a real cost, not a formality |
| Runway at current burn | Determines whether any of the above matters | The most important unanswered question there is |
Do the arithmetic before you feel good about it. Percentage of the company, multiplied by a plausible exit valuation, multiplied by your vested fraction, minus the strike cost and tax. In a smaller ecosystem with fewer exits, run that with a realistic probability attached rather than the best case.
The exercise window is the trap people fall into. You leave after three years, 75% vested, and have 90 days to find the cash for the strike price on shares you cannot sell. Plenty of people walk away from vested options for exactly this reason.
Visa sponsorship
The practical constraint for foreign candidates.
Startups can sponsor, but capacity varies. Sponsorship requires the company to prepare documentation for the Certificate of Eligibility, and a very small company doing it for the first time will be slower and less certain than an established employer — see the Japan engineer visa guide and the Japan work visa guide.
Ask directly: have they sponsored before, and do they use an administrative scrivener or lawyer to handle it? An affirmative answer to either substantially reduces your risk.
Company stability matters for immigration, not just employment. Immigration considers the employer's financial position when assessing a CoE application, so a very early-stage company with little revenue can complicate approval.
If you already hold a status covering the work, this is far simpler — you notify immigration of the change rather than requiring new sponsorship.
Your risk depends heavily on which situation you are in
| Your situation | Risk level | What to do |
|---|---|---|
| Already in Japan, status covers the work | Low | Notify immigration within 14 days; no sponsorship needed |
| Already in Japan, different field | Medium | Get a certificate of authorised employment before accepting |
| Abroad, company has sponsored before | Medium | Proceed, but confirm they use a scrivener |
| Abroad, first-time sponsor, funded and revenue-generating | Medium-high | Ask for the CoE timeline in writing; do not resign early |
| Abroad, first-time sponsor, pre-revenue | High | The financial position may complicate approval |
| Abroad, company has under 12 months' runway | Very high | Reconsider — your status depends on their survival |
The bottom row is the one worth being blunt about. Losing a job at a startup is a career setback in most countries. In Japan on a sponsored status it is also an immigration problem, on a clock, in a country where you may have just arrived.
That is not an argument against joining a startup here — it is an argument for asking about runway with the same seriousness you would ask about salary, and for keeping some savings against the possibility.
Where the scene is
Tokyo dominates, particularly around Shibuya, Roppongi and increasingly other central areas. The overwhelming majority of venture activity and startup employment is here.
Fukuoka has made a deliberate policy effort to attract startups, including a startup visa arrangement, and has a genuine if smaller scene.
Osaka and Kyoto have activity, particularly in manufacturing technology and deep tech linked to universities — see Tokyo vs Osaka jobs.
Sectors with real depth: fintech, HR technology, SaaS, e-commerce, healthcare technology, and increasingly AI applications.
What to check before joining
Runway and funding stage. How long can they operate at current burn?
Is the salary acceptable without the equity? If not, decline.
Working language, genuinely. Ask what language stand-ups, documentation and customer conversations actually happen in — not what the recruiter says.
Sponsorship history, if you need a visa.
Who else is foreign at the company, and at what level.
What happens to your visa if the company fails. A "Designated Activities" status can cover a job-hunting period in some circumstances, which is worth understanding before you need it.
Testing the working language claim
"We work in English" is the single most over-stated thing in Japanese startup hiring, and it is rarely a deliberate lie — founders genuinely believe it because their own meetings happen in English.
Ask about specific artefacts rather than the general policy:
- What language is the codebase commented in?
- What language are the internal docs and the wiki written in?
- What language does the daily stand-up happen in?
- What language do customer support tickets arrive in?
- What language does the company Slack default to?
- If two Japanese engineers pair on a problem, what do they speak?
The honest answer at most Japanese startups is mixed — English for anything international-facing, Japanese for everything internal and everything customer-facing. That is workable, and it is very different from "we work in English".
Ask to speak to a foreign employee before accepting. One fifteen-minute conversation with someone already doing the job tells you more than the entire interview process, and a company that will not arrange it has answered the question anyway.
Common Mistakes
Treating options as salary. The Japanese venture ecosystem is smaller with fewer exits, so equity here warrants more caution than the equivalent elsewhere.
Not asking the percentage. A share count without the total outstanding tells you nothing about what you actually hold.
Ignoring the post-departure exercise window. Ninety days to fund a strike price on unsellable shares is why people walk away from vested options.
Assuming all startups operate in English. It varies sharply, and founders overstate it sincerely — ask about the codebase, the wiki and the stand-up instead.
Not checking sponsorship history. A company sponsoring for the first time is slower and less certain, and their financial position affects the CoE assessment.
Ignoring runway. It is the single most important question about any startup and the one candidates most often skip.
Not asking to speak to a foreign employee. Fifteen minutes with someone already doing the job beats the whole interview process.
Not understanding option tax treatment. It depends on the scheme structure in Japan and can be expensive at exercise.
Treating visa risk as identical to employment risk. If the company fails, your right to remain is affected too, on a clock.
Expecting structure. Training, documented process and defined progression are largely absent, which suits some people and not others.
Frequently Asked Questions
Do Japanese startups hire foreign professionals?
Frequently yes, and more readily than established domestic firms — many operate in English and lack the cohort and seniority conventions that disadvantage foreign mid-career hires.
Is startup equity worth anything in Japan?
Treat it cautiously. The ecosystem is smaller with fewer exits than the US, so accept an offer only if the cash salary works on its own.
What do I need to know to value an option grant?
Total shares outstanding, strike price, last round valuation, vesting schedule and the exercise window after leaving. A share count alone tells you nothing.
What is the exercise window and why does it matter?
The time you have after leaving to buy your vested shares, frequently 90 days. If you cannot fund the strike price in that window, the options are lost.
Do startups sponsor visas?
They can, but capacity varies. Ask whether they have sponsored before and whether they use a professional to handle the paperwork — both reduce your risk considerably.
Do I need Japanese?
It varies sharply by company. Ask what language the codebase, the wiki, the stand-up and customer tickets are in, rather than what the working language is said to be.
What happens to my visa if the startup fails?
Your status is affected, on a clock. A Designated Activities status can cover a job-hunting period in some circumstances, so understand your options before you need them.
Where is the startup scene concentrated?
Overwhelmingly Tokyo, with genuine smaller activity in Fukuoka, Osaka and Kyoto.
How does hiring differ from established companies?
Faster and less formal — weeks rather than months, with no shukatsu cycle, no cohort system and no seniority structure.

Make This Practical
Judge the offer on cash alone. If the salary is not acceptable without the options, the offer is not acceptable — and before you feel good about a grant, get the total shares outstanding, the strike price and the last valuation, because a share count on its own is meaningless.
Then test the language claim against artefacts rather than policy. Ask what the codebase is commented in, what the wiki is written in, what the stand-up runs in, and what language two Japanese engineers use when they pair. The honest answer at most Japanese startups is mixed, which is workable and is not what "we work in English" implies.
Finally, ask about runway with the same seriousness as salary, because on a sponsored status the company's survival and your right to remain are the same question. And ask to speak to a foreign employee before accepting — fifteen minutes with someone already doing the job tells you more than the entire process, and a refusal has answered you anyway.
