Working in Japan as a Foreigner: Rules and Contracts

Receiving a job offer in Japan is an important milestone. But the salary written in the offer is only one part of the decision.

Before your first working day, you should understand whether the job is permitted under your residence status, what your contract actually guarantees, how overtime will be calculated, which deductions will reduce your take-home pay, and what rights you have if something goes wrong.

Many expensive workplace problems begin with a small misunderstanding:

A job falls outside the worker’s permitted immigration activity
A monthly salary quietly includes fixed overtime
A bonus was promised verbally but not written anywhere
A fixed-term contract has unclear renewal conditions
An employee signs a resignation letter while believing they are being dismissed
Required preparation or overtime is not recorded
Social insurance enrollment is treated as optional when it is legally required

This guide explains the system step by step.

The three-document rule: Before working, understand your residence card, your written working conditions and your payslip. Together, these documents tell you whether you may work, what the employer promised and what you were actually paid.

Important Note Before You Read

This article provides general information as of 23 July 2026. It is not individual legal, immigration or tax advice.

Rules may differ according to your residence status, occupation, contract, working pattern, company, industry and personal circumstances. Technical interns, Specified Skilled Workers, dispatched workers, public employees and independent contractors may also be subject to additional or different rules.

For an official decision, consult the responsible government office or a qualified professional.

Step 1: Confirm That Your Residence Status Permits the Job

Employment law and immigration law are separate systems.

Japanese labor laws may protect you as a worker, but that does not mean every residence status allows every kind of employment. You must satisfy both systems.

Residence statuses with work restrictions

Many work-related statuses permit activities within a defined professional field. Examples include Engineer/Specialist in Humanities/International Services, Skilled Labor, Nursing Care, Instructor, Researcher and Specified Skilled Worker.

A new job should match the activity permitted under your status. A job title alone is not enough. Immigration may consider the actual duties, employer, qualifications and relationship between your education or experience and the work.

Residence statuses without immigration-based work restrictions

Permanent Resident, Spouse or Child of Japanese National, Spouse or Child of Permanent Resident and Long-Term Resident generally do not have immigration restrictions on the type of lawful work they may perform.

Professional qualifications may still be required for regulated occupations.

Students and dependents

Student and Dependent status holders generally cannot begin part-time work without Permission to Engage in Activity Other Than That Permitted under the Status of Residence Previously Granted.

When comprehensive permission has been granted:

The usual limit is 28 hours per week
The limit applies to the combined total across all jobs
International students may generally work up to eight hours per day during officially designated long school vacations
Work connected with adult-entertainment businesses is prohibited, even in a role that does not appear entertainment-related

Do not rely only on an employer saying, “It is fine.” Check your residence card and the permission recorded on its reverse side.

Designated Activities status

“Designated Activities” does not have one universal work rule. Your permitted activity depends on the individual designation issued to you. Check your designation document before accepting employment.

When changing jobs

Changing employers does not always require changing residence status, provided the new work remains within the authorized scope. However, many work-related statuses require notification to the Immigration Services Agency within 14 days after leaving or joining an affiliated organization.

If you are uncertain, ask whether you need:

Notification of your affiliated or contracted organization
A Certificate of Authorized Employment
Permission for an additional activity
A change of status of residence

Losing a job does not automatically cancel your residence status. However, prolonged non-participation in the authorized activity can create immigration issues. Keep evidence of job searching and seek advice promptly.

For a broader explanation, read AIC Japan’s Japan Visa, Residence Card and City Office Basics. Official rules are available through the Immigration Services Agency’s work-permission guidance and affiliated-organization notification guidance.

Step 2: Identify Your Real Employment Type

Japanese workplaces use several employment labels. The label matters, but the contract and actual working relationship matter more.

Common arrangement	Japanese term	What to check
Regular employee	Seishain	Often full-time and indefinite-term, but confirm the contract period, duties, transfers and retirement rules
Contract employee	Keiyaku shain	Usually fixed-term; check the end date, renewal criteria, renewal limit and non-renewal procedure
Part-time employee	Paato / arubaito	Core labor protections still apply; paid leave and some insurance coverage depend on working conditions
Dispatched worker	Haken shain	The dispatch agency is normally your employer, while the client company directs daily work
Independent contractor	Gyomu itaku	You may not receive ordinary employee protections or social insurance through the client

“Full-time,” “part-time,” “regular” and “contract” are not enough by themselves. Ask whether your agreement is:

Indefinite-term or fixed-term
Direct employment or dispatch
Employment or independent contracting
Hourly, daily, monthly or annual salary
Subject to a probationary period

Be especially careful with a gyomu itaku contract. It is normally a business-to-business service arrangement, not an employment contract. Taxes, insurance, expenses, working-time protection and termination rules can be very different.

However, authorities may consider the actual relationship, not only the document’s title. If a company controls your time, place, method and daily work like an employer while calling you an independent contractor, seek professional advice.

Step 3: Read the Written Working Conditions Before Signing

Japanese employers must clearly indicate working conditions when hiring. Core conditions must be provided in writing or, when permitted and preferred by the worker, electronically.

A short verbal explanation is not enough.

Your contract checklist

Before accepting the job, confirm all of the following:

Employer: The company’s full legal name and address
Job location: Initial workplace and possible future locations
Duties: Actual responsibilities and the possible scope of changes
Starting date: The exact first day of employment
Contract period: Indefinite or fixed-term
Renewal: Renewal criteria, renewal procedure and any upper limit
Probation: Length, evaluation standards and conditions
Basic salary: The amount excluding allowances and overtime
Allowances: Housing, commuting, position, language or other allowances
Fixed overtime: Included amount and number of hours, if any
Working time: Starting time, finishing time, shifts and breaks
Days off: Weekly days off, company holidays and shift calendar
Leave: Annual paid leave and any company-specific leave
Insurance: Health, pension, employment and workers’ compensation coverage
Payment: Wage-closing date, payday and payment method
Bonus and pay raise: Whether they are guaranteed, conditional or discretionary
Retirement allowance: Whether a system exists and who qualifies
Resignation and dismissal: Notice procedure and stated grounds
Transfers: Whether relocation, transfer or reassignment may be required
Company rules: Which rules of employment apply to you

Current disclosure rules also require employers to clarify the possible scope of changes to the workplace and duties. Fixed-term workers should receive information about renewal standards and any upper limit on the total contract period or number of renewals.

Verbal promises are difficult to enforce

Statements such as these should be written into the offer, contract or applicable company rules:

“Your salary will increase after probation.”
“You will definitely receive two bonuses.”
“Overtime is almost never required.”
“Your contract will automatically be renewed.”
“You can work remotely three days per week.”
“The company will sponsor your residence-status procedure.”

Ask for clarification before signing, not after the problem begins.

Understand fixed overtime

Some Japanese salaries include a fixed overtime allowance, called kotei zangyo-dai or minashi zangyo-dai.

For example, an offer might state:

Total monthly salary: ¥300,000
Basic salary: ¥250,000
Fixed overtime allowance: ¥50,000
Overtime included: 30 hours

The contract should make the arrangement identifiable. If the legally calculated overtime pay for actual hours exceeds the fixed allowance, the additional amount remains payable.

A fixed overtime allowance is not permission for unlimited overtime, and it should not be used to prevent accurate time reporting.

Watch for contract red flags

Pause and ask for advice if:

You are told to sign a blank or incomplete document
The salary breakdown is missing
Fixed overtime hours are not identified
The company refuses to provide a copy
A recruiter demands a large unexplained fee or deposit
The employer wants to keep your passport or residence card
You are threatened with a predetermined financial penalty for resigning
The job described in the interview is different from the written duties
You are pressured to sign a document you do not understand

Japanese law prohibits contracts that predetermine a penalty or fixed compensation for breaching the labor contract. This does not prevent an employer from pursuing proven actual damage in an appropriate case, but a standard “fine for quitting” is a serious warning sign.

Fixed-term conversion

If fixed-term contracts with the same employer are repeatedly renewed for more than five years, the worker can generally apply to convert the relationship into an indefinite-term contract. Certain special rules and exceptions may apply.

Probation is still employment

Probation does not mean the employer may ignore labor law.

The 30-day dismissal-notice rule has an exception during the first 14 days of employment, but probation is not permission for discriminatory or completely arbitrary treatment. After more than 14 days, advance-notice requirements generally apply.

The MHLW Working Conditions Handbook explains the required working-condition disclosures, fixed-term contracts, predetermined penalties and probation-related rules.

Step 4: Understand Gross Salary, Take-Home Pay and Deductions

The salary advertised in a job offer is normally the gross amount before deductions.

Your take-home pay may be lower because of:

Income tax
Resident tax
Employees’ Health Insurance
Employees’ Pension Insurance
Employment Insurance
Long-term care insurance, when applicable
Lawful company deductions

Examine the salary structure

A monthly figure may include:

Basic salary
Position or qualification allowance
Housing allowance
Commuting allowance
Fixed overtime allowance
Shift or night-work allowance
Performance pay

The basic salary matters because bonuses, retirement benefits, overtime calculations and future raises may use it as a reference.

Commuting reimbursement is common in Japan, but it is not automatically guaranteed in every job. Check the written company policy.

Minimum wage

Japan has:

A regional minimum wage for each prefecture
A specified minimum wage for certain industries

If both apply, the higher rate applies. For dispatched workers, the minimum wage at the place where they are dispatched generally applies.

Minimum wages change, so confirm the current rate through the official minimum-wage portal.

Wage-payment basics

In principle, wages must be paid:

Directly to the worker
In full, except for lawful deductions
At least once per month
On a fixed date

Check every payslip against your attendance record. Confirm:

Basic salary
Days and hours worked
Overtime hours
Night and statutory-holiday work
Allowances
Insurance deductions
Income tax
Resident tax
Absence or late-arrival deductions
Net payment

The resident-tax surprise

Resident tax is generally based on the previous year’s income and is commonly collected from June. A newly arrived worker may initially pay little or no resident tax and then see take-home pay fall after the first assessment period.

Do not build a long-term budget using only your first few payslips.

Step 5: Know the Rules for Working Hours and Overtime

The general statutory limits are:

Eight hours per day
Forty hours per week
At least 45 minutes of break when work exceeds six hours
At least one hour of break when work exceeds eight hours
At least one statutory day off per week, or four days during a four-week period

Some industries, working-time systems and legally defined positions have special rules.

Scheduled hours and statutory hours are different

Suppose your contract schedules seven hours per day. If you work one additional hour, that time must be paid, but the statutory overtime premium may not begin until work exceeds the legal eight-hour daily limit, unless your contract or company rules provide a better rate.

Weekly totals and the company’s working-time system must also be considered.

What is an Article 36 Agreement?

Before requiring work beyond statutory hours or on statutory days off, an employer generally needs a valid labor-management agreement known as a Saburoku Kyotei or Article 36 Agreement.

The general overtime limit is:

45 hours per month
360 hours per year

Temporary special circumstances may allow higher limits, but further monthly, annual and multi-month restrictions apply. An Article 36 Agreement does not allow unlimited overtime.

Minimum premium rates

Work performed	General minimum premium
Statutory overtime	At least 25% extra
Work on a statutory day off	At least 35% extra
Night work from 10:00 p.m. to 5:00 a.m.	At least 25% extra
Statutory overtime exceeding 60 hours in one month	At least 50% extra

Premiums can combine. For example, statutory overtime performed at night may require both overtime and night premiums.

Record your real working time

Keep a personal record of:

Clock-in and clock-out times
Shift schedules
Overtime requests and approvals
Computer login records
Emails and work messages
Work performed from home
Required morning meetings or preparation
Time spent waiting under the employer’s control

Changing clothes, preparing equipment, attending required meetings or remaining on standby may count as working time depending on the circumstances.

An employer may require prior approval for overtime, but an approval procedure should not be used to hide work that the employer required, instructed or knowingly accepted.

Unpaid “service overtime,” called sabisu zangyo, is not made lawful simply because it is common in a workplace.

Also, being given “manager” in an English job title does not automatically remove overtime rights. The legal test is based on the person’s actual authority, responsibility, working-time discretion and treatment, not the title alone.

The current MHLW Working Conditions Handbook explains statutory hours, breaks, Article 36 agreements, overtime limits and premium rates.

Step 6: Understand Paid Leave, Public Holidays and Sick Leave

Annual paid leave

A general full-time employee becomes entitled to 10 days of annual paid leave after:

Six months of continuous employment
Attendance on at least 80% of scheduled working days

The entitlement generally increases with continued service, up to 20 days. Eligible part-time workers also receive annual paid leave, usually on a proportional basis.

Employers must ensure that workers who receive at least 10 days of annual paid leave take at least five days within the relevant year.

Workers generally request the timing of their leave. An employer may change the timing if granting it would seriously interfere with normal business operations, but this does not eliminate the leave entitlement. MHLW guidance specifically indicates that chronic understaffing alone is not a sufficient reason to refuse the requested timing indefinitely.

Unused statutory leave generally expires two years after it arises.

Public holidays

Japan’s national holidays are not automatically statutory days off for every private-sector employee.

Your company calendar, contract, shift system and rules of employment determine whether you are off on a particular national holiday. Working on a national holiday also does not automatically create the 35% statutory-holiday premium unless that day is your designated statutory day off.

Sick leave

Japan’s Labor Standards Act does not create a general universal entitlement to paid sick leave for personal illness.

Depending on the company and situation, a worker may use:

Annual paid leave
Company-provided sick leave
Unpaid leave
A leave-of-absence system
Sickness and injury allowance under Employees’ Health Insurance, if the eligibility conditions are met

Ask about the company’s sick-leave policy before you need it.

Legal systems also exist for maternity, childcare and family-care leave. Eligibility and payment rules should be checked separately.

The distinctions between statutory leave, company leave and public holidays are explained in the MHLW Model Rules of Employment.

Step 7: Check Insurance, Pension and Tax Enrollment

Foreign nationality does not make public insurance optional.

Workers’ Accident Compensation Insurance

Workers’ compensation generally covers workers regardless of nationality or whether they are regular, contract or part-time employees.

It can cover work-related and commuting injuries, illnesses, disability and death. The employer bears the insurance premium.

If you are injured:

Report the incident immediately
Record when, where and how it happened
Identify witnesses
Keep medical documents
Tell the medical provider if the injury may be work-related
Contact the Labor Standards Inspection Office if the company refuses to cooperate

Employment Insurance

A worker is generally covered when:

Prescribed working time is at least 20 hours per week
Employment is expected to continue for at least 31 days

Exceptions apply, including rules affecting many daytime students.

Employment Insurance may provide unemployment and other benefits when eligibility conditions are satisfied.

Employees’ Health Insurance and Employees’ Pension

Coverage depends on the workplace and working conditions. Regular workers at covered workplaces are generally enrolled. Part-time workers may also be required to enroll when the applicable criteria are met.

When coverage is legally required, the employer and worker cannot simply agree to opt out. Contributions are generally shared between them and deducted through payroll.

Japan Pension Service confirms that foreign workers are covered under the same statutory criteria. See its current Employees’ Pension and Health Insurance enrollment guidance.

If you are not covered through employment, you may need National Health Insurance and National Pension procedures through your municipality. For additional background, see Living in Japan as a Foreigner.

Income tax and year-end adjustment

Employers normally withhold income tax from salary. For many employees, the employer completes a year-end adjustment.

A separate tax return may still be required in situations such as:

Receiving salary from multiple sources
Significant income outside employment
Receiving certain overseas income
Leaving employment before year-end adjustment
Earning above the applicable filing threshold
Claiming deductions or refunds not handled by the employer

The National Tax Agency explains when wage earners must file a final tax return.

Step 8: Learn the Workplace Basics Without Confusing Culture With Law

There is no single Japanese workplace culture. A traditional manufacturer, international technology company, hospital, restaurant and small family business may operate very differently.

However, several practices are common.

Communicate early

If you may be late, absent or unable to meet a deadline, inform the responsible person as early as possible.

Confirm important instructions

When duties, deadlines or employment conditions are unclear, confirm them in writing. A short follow-up email can prevent a large misunderstanding.

Understand reporting lines

Many workplaces value ho-ren-so:

Hokoku: Reporting
Renraku: Informing
Sodan: Consulting

The practical meaning is simple: do not allow a preventable problem to remain hidden.

Read the rules of employment

A workplace continuously employing 10 or more workers must generally prepare rules of employment, submit them to the relevant authority and make them accessible to workers.

These rules may cover:

Attendance
Overtime
Leave applications
Remote work
Confidentiality
Data protection
Dress and safety
Disciplinary action
Harassment reporting
Resignation procedures

Company rules cannot reduce protections below statutory minimums.

Workplace culture does not justify harassment

Strict supervision, constructive correction and reasonable performance management are not automatically harassment. But cultural explanations do not excuse power harassment, sexual harassment, discrimination or harassment connected to pregnancy, childbirth, childcare leave or family-care leave.

Employers are required to take measures against workplace harassment. MHLW guidance confirms that these protections apply regardless of nationality or residence status. See the ministry’s foreign-worker harassment guidance.

Step 9: Know What to Do if the Job Goes Wrong

Do not wait until all evidence has disappeared.

If wages or overtime are missing

Compare your payslip with your attendance record
Calculate which hours appear to be missing
Ask payroll or HR for a written explanation
Keep the response
Preserve contracts, schedules, messages and bank records
Contact a labor consultation service if the issue is not resolved

If the company has no work

When an employee cannot work for a reason attributable to the employer, the employer may be required to pay an absence allowance equal to at least 60% of the employee’s average wage.

The result depends on the reason and circumstances, so confirm before assuming every business closure qualifies.

If you are told to resign

Japan distinguishes between:

Voluntary resignation
Encouraged resignation
Expiration or non-renewal of a fixed-term contract
Dismissal
Disciplinary dismissal

Do not immediately sign a taishoku todoke, resignation agreement or document stating that you resigned voluntarily if that is not your decision.

Signing can affect the official reason for separation, unemployment procedures and your ability to challenge what happened.

Ask:

Is the company dismissing me?
What is the reason?
What is my final date?
Will I receive notice pay?
How will the separation be recorded?
Can I have the explanation in writing?

Thirty days’ notice does not automatically make dismissal lawful

An employer must generally provide at least 30 days’ advance notice of dismissal or pay the equivalent average wage for the missing notice period, subject to limited exceptions.

But notice and validity are separate questions.

An indefinite-term dismissal that lacks objectively reasonable grounds and is not socially acceptable may be invalid. Paying 30 days’ wages does not automatically give an employer the right to dismiss anyone for any reason.

Fixed-term workers generally cannot be dismissed before the contract expires unless unavoidable circumstances exist.

Protect your evidence

Keep copies outside the employer’s computer or account where lawful:

Employment contract
Notice of working conditions
Rules of employment
Payslips
Attendance records
Shift schedules
Performance evaluations
Overtime instructions
Emails and messages
Warning letters
Medical and accident records
Resignation or dismissal documents

Do not remove confidential company information that you are not entitled to possess.

The MHLW handbook explains the rules on dismissal, unpaid wages, fixed-term employment and workplace injuries.

Step 10: Leave or Change Jobs Carefully

A clean departure protects your immigration status, taxes, insurance and future job search.

Before leaving

Check the notice procedure in your contract and company rules
Submit your resignation in a form that creates a record
Confirm your final working day and final day of employment
Clarify unused annual leave
Return company property
Save personal copies of employment records
Confirm final salary and expense reimbursement

Resignation timing can differ between indefinite and fixed-term contracts. Fixed-term workers should seek advice before leaving early if the employer disputes the departure.

Request the necessary documents

Depending on your situation, you may need:

Withholding Tax Certificate: Gensen Choshu-hyo, 源泉徴収票
Employment Insurance Separation Notice: Rishoku-hyo, 離職票
Employment Insurance Insured Person Certificate: Koyo Hoken Hihokensha-sho, 雇用保険被保険者証
Retirement Certificate: Taishoku Shomeisho, 退職証明書
Health-insurance loss-of-eligibility document: Kenko Hoken Shikaku Soshitsu Shomeisho, 健康保険資格喪失証明書

The documents you need depend on whether you are starting another job immediately, applying for unemployment benefits or changing to municipal insurance.

Complete insurance and pension procedures

If your next employer will not enroll you immediately, ask the city office and pension office about:

National Health Insurance
National Pension
Dependent coverage through a spouse
Voluntary continuation of employee health insurance, when eligible

Do not assume that coverage changes automatically.

Check resident tax

After leaving, resident tax may:

Continue through your final salary
Be collected in a lump sum
Be changed to payment slips sent to your address
Transfer to the new employer later

Confirm the method before moving or leaving Japan.

Complete immigration notification

If your status requires notification of a change in affiliated or contracted organization, submit it within the required period, commonly 14 days.

Your next job must also remain within the permitted activity. Unemployment benefits, labor rights and immigration permission are separate matters.

For immigration questions, contact the Information Center for Foreign Residents at 0570-013904 within Japan.

Four Practical Examples

Example 1: A student has two part-time jobs

The student works 18 hours at a restaurant and 15 hours at a convenience store.

The total is 33 hours. The ordinary limit is calculated across both jobs, so this may violate the 28-hour permission even though neither job individually exceeds it.

Example 2: A monthly salary includes overtime

The offer says “¥300,000 per month,” but the contract later reveals that the figure includes 40 hours of fixed overtime.

The worker should identify the basic salary, fixed allowance, included hours and payment due when actual overtime exceeds the included amount before accepting.

Example 3: The employer says, “You are fired tomorrow”

The worker should ask for the reason and decision in writing. The employer may have a notice-pay obligation, and the dismissal may still be challengeable if it lacks valid grounds.

The worker should not sign a voluntary-resignation document merely to complete the meeting quickly.

Example 4: The company opens on a national holiday

A national holiday is not automatically a statutory day off for every private-sector worker. The result depends on the company calendar and which day is designated as the worker’s statutory day off.

Final Employment Checklist

Before accepting:

Confirm immigration permission
Identify the real employment type
Read the entire contract
Separate basic salary from fixed overtime
Check the workplace, duties and transfer scope
Confirm contract renewal conditions
Estimate take-home pay
Check insurance enrollment
Keep a copy of everything

After starting:

Obtain the rules of employment
Record actual working time
Check every payslip
Learn the leave procedure
Keep immigration and employment deadlines
Ask questions in writing

When leaving:

Confirm whether it is resignation, dismissal or non-renewal
Do not sign inaccurate documents
Request separation and tax documents
Complete insurance and pension procedures
Check resident tax
Submit immigration notification if required

Final Thoughts

Working in Japan can offer stability, professional growth and valuable international experience. But a good working life begins with clarity.

Do not judge an offer only by the monthly salary. Check the legal permission, employment type, contract period, basic salary, overtime structure, insurance and exit conditions together.

A reliable employer should be able to explain these matters clearly.

The most useful habit is simple:

Do not guess. Ask, confirm and keep a written copy.
