The contract that quietly made our contractor an employee — the 7 steps I now run before any 業務委託 engineer in Japan

The failure looks the same every time. A company needs a senior engineer, hiring is slow, and someone finds a strong developer willing to work on a 業務委託 contract — gyomu itaku, business entrustment. It works. Six months later the arrangement is renewed without discussion. The engineer is in the standup, owns a service, is in the on-call rotation, and has a company laptop.

At that point the contract says one thing and the working relationship says another, and in Japan only the second one counts.

This is not a story about bad actors. Almost every instance I have seen was a well-intentioned team that hired the way it knew how and never revisited the paperwork. The purpose of this guide is to make the substance test visible before it becomes an inspection finding — and to be clear about what the Freelance Act, in force since 1 November 2024, now requires from you regardless of the classification question.

As always: this is an operational guide written from hiring practice, not legal advice. Have your template reviewed by a Japanese employment lawyer or a 社会保険労務士 before you use it.

Step 1: Accept that the label decides nothing

Japanese labour law protects workers, and whether someone is a worker is a question of fact. The concept is 労働者性 (rodosha-sei), literally “worker-ness”, and the analytical framework in general use descends from the Labour Standards Act study group report of the mid-1980s. It has been applied by courts and labour inspectors ever since.

A clause stating that the individual is an independent business operator and not an employee is not worthless — it is evidence of what the parties intended. But it sits at the bottom of the stack, underneath every fact about how the work was actually done. Where intention and practice disagree, practice wins.

Three different authorities can reach this question by three different routes, which is why it rarely stays contained:

• A Labour Standards Inspection Office looking at hours and unpaid overtime.
• The pension and health insurance side, asking whether the person should have been enrolled in 社会保険 all along.
• A court, when a relationship ends badly and the individual argues the termination was a dismissal.

Step 2: Run the six substance tests before you sign

Here is the framework, in the order I actually apply it. The first five are the core; the sixth is the supplementary set that tips borderline cases.

Two of these deserve a warning because engineering teams get them wrong in a specific way.

Remuneration basis. A monthly retainer is not automatically fatal, but a monthly retainer that moves when hours move is close to it. If your finance system is computing a rate multiplied by hours, you are paying for time.

Business-operator character. Exclusivity is the quiet one. An engineer who works only for you, has done so for two years, and has no other clients looks like an employee to an inspector no matter how the contract reads.

Step 3: Separate the contract from the workflow

This is the step that has nothing to do with legal drafting and does most of the damage.

A service contract in which the client directs the individual’s daily work is not a service contract. It is 偽装請負 (gisou ukeoi), disguised contracting, and the effect is that you are operating worker dispatch — a licensed activity under the Worker Dispatch Act. Where an agency sits in the middle, the exposure does not sit only with the agency.

The reason engineering teams walk into this is that every good engineering practice looks like direction. Daily standup. Sprint assignment. Code review with required changes. On-call rotation. Each is a reasonable way to run software delivery and each is evidence that you are directing the work.

You have two coherent options, and the incoherent middle is where the risk lives:

1. Contract for outcomes. Define deliverables and acceptance criteria. Let the contractor decide method and schedule. Review output, not activity. Do not put them in the on-call rotation.
2. Hire them. Direct employment, or an employer of record if you have no entity yet. If you want an engineer embedded in your team the way employees are, that is what they are.

Most teams want option two and are paying for option one because hiring felt slow six months ago.

Step 4: Issue written terms before work starts

Independent of the classification question, the Act on Ensuring Proper Transactions Involving Specified Entrusted Business Operators — the Freelance Act — has applied since 1 November 2024. It covers business entrustment to an individual who operates without employees, which describes most freelance engineers in Japan.

Its first duty is the easiest to comply with and the most commonly breached: the terms of the entrustment must be provided in writing or electronically before the work begins. Scope, deliverables, amount, payment date, and the parties. An engagement that begins on a Slack message and a handshake is non-compliant on day one, however good the working relationship.

The Act also requires measures against sexual, power and maternity harassment toward freelancers — the same protective logic that applies to employees — and adds prohibitions on continuing transactions, including unjust price reductions and unjust refusal of receipt. Enforcement runs through the Japan Fair Trade Commission and the labour authorities, with guidance and recommendations escalating from there.

Step 5: Fix the payment clock at 60 days from acceptance

The Freelance Act sets a hard outer limit on payment terms: payment is due within 60 days of the client receiving the deliverable. Two details matter and both are routinely missed.

First, the clock runs from receipt of the work, not from the invoice date. A workflow in which the contractor invoices at month end and you pay on standard terms can breach the limit while every individual step looks normal.

Second, a contract clause providing for a longer period is void. It does not create a negotiated exception; it simply fails, and the statutory limit applies instead.

If your accounts payable process runs on a fixed monthly cycle designed for corporate vendors, this is worth a specific check rather than an assumption. It is also the single most common finding when a freelance engagement is reviewed for the first time.

Step 6: Plan termination and notice before you need them

For an entrustment that runs six months or more, the Act requires 30 days advance notice of termination or non-renewal. There are limited exceptions, but the default is 30 days and you should plan on it.

Set against that the other scenario. If the relationship is later found to have been employment in substance, ending it was not the expiry of a contract — it was a dismissal, and dismissal in Japan must be objectively reasonable and socially acceptable to be valid. That is a materially higher bar than most non-Japanese employers expect, and an invalid dismissal can mean reinstatement and back pay.

Step 7: Price the reclassification exposure before you scale the model

One contractor is a question. Ten contractors on the same template is a population, and a finding against one is a finding against the pattern.

Model the downside honestly before you scale. The components, roughly in order of size:

• Social insurance. Retroactive enrolment with the employer share of premiums. Our breakdown of what shakai hoken actually costs per engineer is the right starting point — the employer share is the number most budgets omit.
• Unpaid overtime. Once someone is a worker under the Labour Standards Act, statutory hours and premium rates apply to what they already worked.
• Paid annual leave. Statutory entitlement accrues from the start of the relationship, not from the finding.
• Dismissal exposure, if the relationship has already ended.
• The multiplier. Everything above, times everyone on the template.

Put a number on that before the tenth contract, not after. In practice the exercise usually reveals that the genuinely independent specialists — the security consultant, the fractional data architect — are fine, and the four “contractors” who are functionally on the platform team are not.

The three mistakes that cost the most

• Copying a Western contractor template. A US-style independent contractor agreement disclaims employment in language that carries almost no weight in Japan, and omits the Freelance Act duties entirely.
• Renewing without re-testing. Relationships drift toward employment. The engagement that passed the substance test at signature often fails it at the third renewal, and nobody looked.
• Using contracting to avoid a hiring decision. If you want someone embedded in the team long-term, that is employment. The contract structure will not change what the relationship is; it will only delay when you find out.

Worth noting that this is a specifically Japanese problem shape, not a universal one. Singapore draws the contractor line differently and enforces it through a different mechanism — HireDeveloper.sg covers the pass and quota framework there — while in the UAE the constraint is the work permit itself rather than a substance test, which HireDeveloper.ae sets out.

Conclusion

Gyomu itaku is a legitimate and useful structure in Japan. It is the right instrument for genuinely independent specialists who bring their own tools, keep their own clients, and are engaged for defined outcomes.

It is the wrong instrument for a person you want in your standup every morning, and no amount of drafting fixes that mismatch. Run the six tests before you sign, re-run them at every renewal, meet the Freelance Act duties whichever side of the line you land on, and price the downside before you scale the template past a handful of people.

The whole exercise takes an afternoon. The alternative takes considerably longer and arrives at a time of someone else’s choosing.

This article is an operational reading of published Japanese law and guidance and does not constitute legal advice. Worker status, Worker Dispatch Act exposure and Freelance Act obligations are assessed case by case — have your contract template and working practices reviewed by a Japanese employment lawyer or a certified social insurance and labour consultant (社会保険労務士) before relying on them.
