Why Your Japanese Employment Contract Really Matters
In Japan, your contract (and the written โworking conditionsโ notice) is more than just paperwork. It controls:
- How much you are paid and how that pay is calculated
- Your working hours, overtime, and days off
- Your visa stability and future career options
- How hard it is for the company to dismiss you
Japanese labour law sets minimum standards for things like working hours, overtime pay, and dismissal procedures. Companies are not allowed to go below these minimums, even if a contract says so.
What A Japanese Employment Contract Must Include
Under the Labour Standards Act, employers must clearly indicate your core working conditions in writing before you start work.
At minimum, the company must show:
- Contract period (fixed term or indefinite)
- Renewal rules if it is a fixed-term contract
- Workplace and job content
- Working hours, breaks, overtime, days off, and leave
- Wages and payment method
- Promotion and retirement (including reasons for dismissal)
Here is a simple overview of key items and where you usually find them:
| Item you should see | Where it appears | What to check carefully |
|---|---|---|
| Contract period | Contract header, โTerm of employmentโ | Fixed term or no end date? Any trial period? |
| Job title and duties | โPositionโ or โJob descriptionโ | Does it match what HR told you? Any phrase like โand other tasks as orderedโ? |
| Workplace | โPlace of workโ | One location or many? Transfer to other branches? |
| Working hours | โWorking hoursโ or โScheduleโ | Start/finish times, breaks, shift work, night work |
| Overtime and 36 Agreement | Overtime clause | Is overtime โdeemedโ or โincludedโ in salary? How many hours? |
| Days off and holidays | โDays offโ, โHolidaysโ | Weekly days off, national holidays, company holidays |
| Wages | โSalaryโ, โBase salaryโ, โAllowancesโ | Base pay, allowances, overtime calculation, bonuses |
| Social insurance | โBenefitsโ | Enrollment in health insurance, pension, employment insurance |
| Probation | โProbation periodโ or โTrial periodโ | Length, conditions, how termination works |
| Retirement and dismissal | โTerminationโ or โRetirementโ | Notice period, reasons for dismissal, non-renewal rules |
If any of these are missing or vague, ask HR or your recruiter to explain in writing before you sign.

Contract Types In Japan You Need To Know
The label on your contract matters. It affects job security, promotion chances, and sometimes your visa.
Indefinite employment
Many full-time โseishainโ positions use an indefinite-term contract with no fixed end date.
- This is usually the most stable type.
- Dismissal is possible, but Japanese courts expect reasonable grounds and the company must follow strict procedures.
Fixed-term employment
A fixed-term contract has a clear start and end date (for example, one year). The general rule is that the term cannot be longer than three years at once, except for certain special roles.
Important points:
- Many ALT, language school, and dispatch jobs use 6โ12 month fixed terms.
- The contract might say โrenewableโ or โnon-renewable.โ
- Repeated renewals for more than five years in total with the same employer can give you the right to request conversion to an indefinite-term contract, under Article 18 of the Labor Contracts Act.
If your total fixed-term period passes five years, and you want to stay, ask HR about your right to apply for indefinite-term conversion.
Dispatch and outsourced contracts
Some foreigners work through a dispatch company (haken) or are technically employees of an agency while working at a client site. In these cases:
- Your contract is with the dispatching company, not the client.
- You must still receive written working conditions from your employer.
- Your day-to-day duties may be influenced by both companies.
If you are unsure who is actually employing you, clarify this immediately. It affects your rights if something goes wrong.

Probation Period In A Japanese Contract
Most Japanese employment contracts have a probation period (่ฉฆ็จๆ้ / shiyล kikan), usually between three and six months.
During probation, the company checks if you fit the job and the culture. However, this is not a free trial for the employer:
- You are still a regular employee with rights.
- If you have worked more than 14 days, the usual 30-day notice or pay in lieu rules for dismissal already apply.
- Termination must still be based on objective, reasonable grounds (for example, clear performance problems or serious misconduct).
Check in your contract:
- Exact length of probation
- Any differences in salary, benefits, or bonus during probation
- Conditions for passing or failing probation
If the contract says something like โThe company may dismiss the employee at any time during probation without notice or reason,โ that is a red flag and may not match Japanese law.

Working Hours And Overtime In Japan
Your contract must clearly explain your working hours, break times, days off, and whether overtime is expected.
Legal limits
Under the Labour Standards Act:
- Standard working hours: up to 8 hours per day and 40 hours per week
- At least 1 day off per week, or 4 days off every 4 weeks
- Overtime beyond these limits requires:
- A filed โ36 Agreementโ between company and workersโ representative
- Payment of overtime premium wages
Typical premium rates are:
- Overtime beyond legal hours: 25% extra or more
- Late-night work (usually 10 pmโ5 am): 25% extra
- Work on statutory holidays: 35% extra or more
- Overtime exceeding 60 hours per month: 50% extra or more (now also applied to most SMEs)
Your contract may say that a certain number of hours of overtime are โdeemedโ or โincludedโ in your salary. If so, check:
- How many hours are included each month (for example, 20 or 40)
- How additional overtime beyond that is paid
- Whether the deemed overtime seems realistic or excessive
If overtime expectations seem heavy, read Labor Laws in Japan: 10 Rights Foreign Workers Should Know and consider whether the workโlife balance is acceptable for you.
Salary, Bonuses And Allowances
Salary structure
Japanese contracts often separate your pay into:
- Base salary
- Allowances (transport, housing, position, language, etc.)
- Overtime pay (fixed or variable)
The contract should explain:
- Gross monthly salary and any annual salary scheme
- Pay calculation: hourly, daily, or monthly
- Payday and closing date (for example, closing on the 20th, payment on the 25th)
Bonuses and pay raises
Bonuses are common in Japan, often paid twice a year (summer and winter). However:
- Bonuses are usually not legally guaranteed unless clearly specified.
- Many contracts say bonuses are โdiscretionaryโ and depend on performance and company results.
Check the wording in your contract:
- If it says โbonus may be paid at company discretion,โ you should not treat this as guaranteed income.
- If the company says โtwo monthsโ salary x 2 per yearโ in writing, this is stronger, but still may depend on performance.
Pay raises are often mentioned in general terms, such as โsalary reviews once per year.โ This does not mean an automatic raise, but it shows there is a review process.
Deductions
Your payslip will show deductions for:
- Income tax and local resident tax
- Health insurance and pension
- Employment insurance
- Possibly company housing or lunch deductions
The contract or work rules should explain which deductions are allowed. The company cannot freely deduct random penalties from your salary.

Leave, Holidays And Social Insurance
Paid leave
Under Japanese law, full-time employees who have worked for 6 months and meet attendance conditions get at least 10 days of paid annual leave, increasing with years of service.
Your contract or work rules should state:
- How many paid leave days you receive
- How they increase with length of service
- Whether the company adds any extra special leave (seasonal holidays, company holidays, etc.)
Even though many Japanese workers hesitate to use vacation, paid leave is your legal right.
National and company holidays
Contracts often list:
- Whether national holidays are days off
- Company-specific holidays (New Year, Golden Week period, Obon, etc.)
Some companies give days off on all national holidays. Others require you to work some holidays but give different days off. Read the schedule carefully.
Social insurance
Most medium and large employers must enroll you in:
- Health insurance
- Employeesโ pension insurance
- Employment insurance
- Workersโ accident compensation insurance
Your share is deducted from your salary, but in return you get:
- Lower medical costs
- Pension accumulation (with possible lump-sum withdrawal later)
- Protection if you are injured at work or laid off
If your contract does not mention social insurance at all, and you are working regular hours, this is a warning sign.

Work Rules And Company Policies
In addition to your contract, Japanese companies are required to prepare work rules (ๅฐฑๆฅญ่ฆๅ / shugyล kisoku) if they employ 10 or more workers. These rules must be filed with the Labour Standards Inspection Office.
Work rules usually cover:
- Start/finish times, breaks, and shifts
- Leave and holidays
- Promotions and demotions
- Disciplinary actions and dismissal rules
- Harassment policies, dress code, IT use, etc.
If there is a conflict between your contract and the work rules and the work rules are better for you, the better standard generally applies. If the contract is below legal or work rule standards, that part is usually invalid.
Always ask for:
- An English summary of work rules, or
- A chance to sit down with HR and go through important points
This is especially important for understanding disciplinary procedures and what happens if there are problems.
Termination, Notice And Non-Renewal
No one likes to think about the end of a job when they are just starting, but this part of the contract is critical.
Notice period
The Labour Standards Act generally requires employers to give 30 daysโ notice before dismissal or pay 30 daysโ average wages in lieu of notice, even during probation (after 14 days of work).
Your contract may also specify:
- How much notice you must give if you resign
- Any penalties if you leave without sufficient notice (these must still follow legal limits)
Reasons for dismissal
Japanese law expects dismissal to have objectively reasonable grounds and to be appropriate in societyโs view.
Contracts often list examples:
- Serious misconduct
- Repeated poor performance after warnings
- Major rule violations
- Business downsizing
If the dismissal clause is extremely vague or seems to allow firing โat will,โ this conflicts with Japanese practice and is a red flag.
Non-renewal of fixed-term contracts
If you are on a fixed-term contract, the company can choose not to renew at the end date. However, if the contract has been renewed many times and you could reasonably expect renewal, a sudden non-renewal may be treated similarly to dismissal in some cases.
Your contract should explain:
- Renewal conditions
- Notice period for non-renewal
- Whether you can request conversion to an indefinite-term contract after five years
If you feel your non-renewal is unfair, seek advice quickly (see โWhere To Get Helpโ below).

Common Red Flags In Japanese Employment Contracts
Here are some warning signs to watch for:
- No written contract or written working conditions at all
- Very vague job description like โother tasks as orderedโ with no main duties
- Extreme overtime expectations with no clear pay rules
- Contract says overtime is โincludedโ but does not state how many hours are included
- No mention of social insurance even though you are full-time
- Clauses saying the company can fire you โat any time, without reason and without noticeโ
- Penalties or large fines if you resign, especially for normal job types
If you see several of these, pause and ask questions. For many foreigners, checking with a union, lawyer, or trusted friend in Japan before signing is a smart move.
