Before You Accept a Job in Japan: A Practical Contract Checklist

Do not sign until the employer has clearly stated your pay, working hours, duties, workplace, contract period, renewal rules, and dismissal terms. Check these against the job advertisement and offer email, and ask for every important promise in writing.

This guide is for foreign residents, international students moving into full-time work, and workers changing employers in Japan. It explains how to review a Japanese employment contract without assuming that you already understand terms such as shūgyō kisoku or fixed overtime pay.

What to check first

Is the salary figure monthly, annual, gross, or take-home pay?
Does the stated salary include a fixed overtime allowance?
Is the job permanent or fixed-term, and is there a renewal limit?
Where can the company transfer you, and how widely can it change your duties?
Is the work permitted under your current or intended status of residence?

If any answer is unclear, pause. A verbal explanation is useful, but a revised document is safer.

First, identify the documents in front of you

A job advertisement, offer letter, employment contract, and notice of working conditions do not necessarily serve the same purpose. Read them together and flag any differences before accepting the job.

You may receive documents with names such as:

Employment contract — koyō keiyakusho (雇用契約書)
Notice of working conditions — rōdō jōken tsūchisho (労働条件通知書)
Job offer notice — naitei tsūchisho (内定通知書)
Rules of employment — shūgyō kisoku (就業規則)
Salary regulations — chingin kitei (賃金規程)

Under Japan’s Labour Standards Act, an employer must clarify specified working conditions when concluding a labor contract. Core matters—including wages, working hours, and certain contract conditions—must generally be provided in writing. Electronic delivery can be used when the worker requests it and can save or print the information.

The employer’s form may combine the contract and notice into one document. The title matters less than whether the required terms are clear and consistent.

Compare every version

Place the advertisement, recruiter message, offer letter, and final contract side by side. Check for changes in:

employer name and employing entity;
job title and actual duties;
workplace and remote-work arrangements;
salary, allowances, bonus, and pay date;
working hours, days off, and expected overtime;
contract length and renewal conditions.

A recruiter may describe a “Tokyo position,” while the contract permits transfers to every office in Japan. A job advertisement may display an annual compensation estimate that includes a conditional bonus. Those differences affect your daily life and should not remain hidden in general wording.

Read the salary from the bottom up

The headline salary is not enough: you need to know the guaranteed base pay, each allowance, and what work the total amount covers. Contract amounts are normally stated before tax and social-insurance deductions, so they are not the amount deposited into your bank account.

Look for these items:

Basic salary — kihonkyū (基本給)
Fixed overtime allowance — kotei zangyō-dai (固定残業代)
position, qualification, housing, or family allowances;
commuting-expense rules and any monthly cap;
pay calculation period and payment date;
salary review timing and whether an increase is guaranteed;
bonus conditions and whether the bonus is fixed, discretionary, or based on performance;
deductions allowed under law or a labor-management agreement.

Treat fixed overtime as a calculation, not a benefit

A salary may include an allowance corresponding to a stated number of overtime hours. Ask the employer to show:

the basic salary excluding overtime;
the fixed overtime amount;
how many hours and which categories of work it covers;
how additional overtime is paid after the included amount is exceeded.

Fixed overtime does not normally mean unlimited unpaid overtime. The Ministry of Health, Labour and Welfare explains that the ordinary-wage portion and overtime portion must be distinguishable, and any shortfall against the legally calculated premium must be paid.

Japan’s statutory premium is generally at least 25% for qualifying overtime and late-night work from 10 p.m. to 5 a.m., and at least 35% for work on a statutory holiday. Overtime beyond 60 hours in one month generally attracts a premium of at least 50%. How these premiums combine depends on when the work occurs.

Check whether a bonus is truly guaranteed

A phrase such as “bonus: twice yearly” does not by itself tell you the amount or guarantee payment. Find out whether the bonus is:

a fixed contractual amount;
calculated under salary regulations;
linked to individual or company performance;
available during probation;
prorated in the first year;
payable only to employees still employed on a specified date.

When comparing offers, calculate guaranteed annual cash compensation separately from a possible bonus. Also keep commuting reimbursement separate unless the employer explicitly includes it in compensation.

Confirm the real working schedule

The contract should let you work out when a normal day starts, when it ends, and when extra pay may begin. “Eight working hours” does not include an unpaid meal break.

Check the following:

starting and finishing times;
break duration;
regular working days and holidays;
whether shifts, flextime, variable hours, or a discretionary work system applies;
whether overtime is required;
how attendance is recorded;
rules for remote work and travel time;
whether Saturday, Sunday, and national holidays are regular days off.

The general statutory limit is eight working hours per day and 40 per week, subject to legal exceptions and special working-time systems. An employer also needs an Article 36 labor-management agreement to require statutory overtime or statutory-holiday work. That agreement does not remove the obligation to pay the applicable premium.

Do not assume that every public holiday is automatically a paid day off for your position. Check the employer’s calendar and the rules of employment.

Paid leave starts under legal conditions

A standard full-time worker generally becomes entitled to 10 days of annual paid leave after six months of continuous employment and attendance on at least 80% of scheduled working days. Part-time workers may receive a proportional number of days.

The contract may provide better terms, but it should not be read in isolation. Ask when leave becomes available, how requests are submitted, whether company-wide closure days consume annual leave, and how unused days are handled.

Check how far the company can move you or change your work

One of the most important current disclosures is the possible future scope of your workplace and duties. Since April 2024, employers must clarify not only the initial workplace and duties but also their expected scope of change.

Compare wording such as:

“Tokyo office” versus “all domestic and overseas offices”;
“software development” versus “all duties assigned by the company”;
“home-based work” versus “a workplace designated by the company.”

Broad language may permit transfers or reassignment, although the legality of a specific future order depends on the contract, the employer’s rules, and the circumstances. If location matters because of housing, childcare, a partner’s work, accessibility, or immigration requirements, ask for a narrower written term before signing.

ここがポイント: The contract should show both where and what you will do at the start, and how far those conditions may change later. A job title alone does not answer either question.

Remote work deserves the same attention. Confirm whether it is a contractual arrangement or a policy the company can change, how often office attendance is required, who pays for equipment and internet service, and whether working from another prefecture or country needs approval.

Understand the contract period and renewal rules

A fixed-term contract needs a clear end date and a realistic explanation of renewal. Do not treat “renewable” as equivalent to permanent employment.

Look for one of these basic forms:

Indefinite-term contract — no predetermined ending date
Fixed-term contract — ends on a stated date unless renewed

For a fixed-term position, check:

the start and end dates;
whether renewal is possible, expected, or not offered;
the criteria used to decide renewal;
any maximum number of renewals or total contract period;
when the employer will make and communicate the decision;
whether the employer can change a newly introduced renewal limit.

The April 2024 disclosure rules added clearer requirements concerning renewal caps. When a company introduces or shortens a cap after the first contract, it must explain the reason to the worker in advance.

The five-year rule is not automatic permanent employment

Under the Labor Contract Act, a worker whose fixed-term contracts with the same employer have been repeatedly renewed for more than five years can generally apply to convert the contract to an indefinite term. Exceptions and special rules exist. Conversion also does not automatically create the salary, title, or benefits of another category of permanent employee.

At the renewal that creates the right to apply for conversion, the employer must clarify the opportunity to apply and the working conditions after conversion. If this may apply to you, consult the Ministry’s official indefinite-contract conversion information rather than relying only on an informal HR summary.

Do not confuse probation with a disposable contract

A probation period does not erase ordinary labor protections. Its length, conditions, and effect on pay or benefits should be written clearly.

Check:

the exact probation dates;
whether salary, leave, remote work, or benefits differ;
the assessment standards;
whether the period can be extended and under what conditions;
what happens if the assessment is unsuccessful.

A contract might contain both a fixed term and a probation clause. Ask the employer to explain which mechanism applies and what happens at each date. Do not assume that passing probation guarantees renewal of a separate fixed-term contract.

Read the rules on resignation and dismissal

You should know the exit rules before the first day, not when a problem occurs. Find the sections covering resignation, retirement, dismissal, disciplinary action, and return of company property.

Important questions include:

How much notice does the company request for resignation?
Where and how must notice be submitted?
What are the grounds and procedures for dismissal?
What conduct can lead to disciplinary action?
Is there a mandatory retirement age?
Are there post-employment confidentiality or non-compete clauses?
How are unused expenses, final wages, and company housing handled?

A contract clause does not automatically settle whether a dismissal or restrictive covenant is legally valid. Japanese labor law places limits on dismissal, and the facts matter. Obtain individual advice if a proposed clause could seriously limit your next job or if the employer asks you to resign immediately.

Check benefits, insurance, and hidden costs

Benefits affect both take-home pay and household planning, but not every worker joins every scheme on identical terms. Eligibility can depend on working hours, contract duration, workplace size, age, and other conditions.

Ask HR to identify the applicable arrangements for:

Employees’ Health Insurance;
Employees’ Pension Insurance;
Employment Insurance;
Workers’ Accident Compensation Insurance;
commuting expenses;
company housing or rent support;
relocation expenses;
dependent or family allowances;
retirement allowance;
childcare and family-care leave procedures.

Confirm whether housing, relocation, visa support, or training costs must be repaid if you leave early. Ask for the repayment formula and triggering conditions in writing. Do not estimate take-home pay by subtracting a single percentage: income tax, resident tax, and social-insurance deductions follow different rules and timing.

Make sure the work matches your immigration status

An employment contract does not by itself give you permission to perform the job in Japan. Immigration status and labor rights are related, but they answer different questions.

A work-authorized status of residence permits specified activities. Statuses such as Student or Dependent generally require permission before paid work outside their main permitted activity, and a comprehensive permission commonly limits eligible part-time work to 28 hours per week. Individual conditions and prohibited activities still matter.

Before signing, verify:

the exact employing company named in the contract;
the real duties, not only the English job title;
the primary workplace;
the intended start date;
whether a status change or other immigration procedure is required first;
whether side work is permitted by both immigration rules and company policy.

Permanent Resident, Spouse or Child of Japanese National, Spouse or Child of Permanent Resident, and Long-Term Resident statuses generally do not restrict work by occupational category. Other statuses may be tied to the kind of activity performed. Use the Immigration Services Agency’s current status-of-residence information or obtain qualified advice for your particular case.

Ask about the rules of employment

The contract may refer to a separate rulebook that contains much of the detail. Request access before signing when possible, especially if the contract says that unspecified matters follow the company’s rules.

The rules of employment may cover:

attendance, lateness, and absence;
leave procedures;
transfer and secondment;
salary calculations;
disciplinary grounds;
resignation and retirement;
remote-work requirements;
side jobs;
confidentiality and data security.

Employers that continuously employ 10 or more workers at a workplace generally must prepare and file rules of employment. The rules must also be made known to workers. Smaller employers may still maintain them voluntarily.

If you cannot read Japanese well enough to understand a document, request an English explanation or translation. An English summary can help, but ask which language controls if the versions conflict. For a high-value offer or an unusually restrictive clause, consider an independent professional translation.

A practical review process before signing

Reviewing the contract in a fixed order makes omissions easier to find. Save the complete document, including attachments and linked policies.

Step 1: Mark the parties and dates

Confirm the legal employer, your name, contract start date, contract end date if any, and signature date. A group brand name may differ from the company that will pay and employ you.

Step 2: Rebuild the offer in plain English

Write a one-page summary containing:

guaranteed monthly basic pay;
fixed overtime amount and included hours;
normal schedule and days off;
workplace and transfer scope;
initial duties and possible changes;
contract period, probation, and renewal cap;
guaranteed benefits and conditional benefits.

If you cannot complete a line, the document needs clarification.

Step 3: List every mismatch

Record differences between the advertisement, interviews, offer, contract, and rules of employment. Send focused questions rather than asking HR whether the contract is “standard.”

For example:

The offer email states that the role is fully remote, but the contract allows assignment to any company workplace. Please confirm the required attendance pattern and revise the workplace clause if the role is limited to remote work and the Tokyo office.

Step 4: Request corrections in the document

Ask for a revised contract or written addendum when an answer changes or limits a clause. Keep the final signed version, attachments, emails, and the rules that applied when you joined.

Step 5: Check immigration timing

Do not begin restricted work merely because the company wants an early start. Confirm any required status change or permission and keep evidence of the actual duties offered.

Common mistakes to avoid

Most contract problems begin with an assumption that was never written down. Watch for these recurring errors:

treating gross salary as take-home pay;
comparing annual salaries without separating conditional bonuses;
overlooking fixed overtime embedded in the monthly figure;
assuming “weekends off” includes every national holiday;
reading a renewable one-year contract as guaranteed long-term employment;
ignoring broad transfer or duty-change language;
assuming remote work is permanent because interviews were online;
signing without reading referenced company rules;
relying on a translated summary while the Japanese version contains additional clauses;
assuming an employer’s offer confirms immigration eligibility.

A seal or hanko may still appear in the signature process, but the real issue is informed agreement. Do not let a request to sign quickly replace a careful review.

When to get help

Seek outside help when the employer will not clarify essential terms, when documents conflict, or when a clause could create a serious financial or immigration risk. Keep copies of the contract, payslips, attendance records, and relevant messages.

The Ministry of Health, Labour and Welfare provides information for foreign workers, multilingual consultation services, and a free Labour Standards Advice Hotline. Prefectural Labour Bureaus and Labour Standards Inspection Offices can also provide guidance within their responsibilities.

For immigration questions, use the Immigration Services Agency or a qualified immigration professional. For individual disputes, dismissal, repayment demands, or restrictive covenants, consider advice from a lawyer, labor union, or appropriate public consultation service.

Final check before you accept

A workable contract should let you answer these questions without guessing:

What is guaranteed pay, and what is conditional?
What hours and overtime system apply?
Where can the company require you to work?
How far can it change your duties?
When does the contract end, and how is renewal decided?
Which benefits and deductions apply?
Does the actual job fit your immigration status?
Which separate company rules become part of the working arrangement?

If one of these remains unclear, your next step is concrete: highlight the clause, ask one written question, and request a corrected document before signing.
