Employment Contracts in Japan: The 2026 Guide to Working Conditions, Work Rules & Dismissal

An employment contract in Japan is the document that turns a job offer into an enforceable relationship, and Japan’s labour framework is detailed and strongly protective of employees. The Labor Standards Act and Labor Contract Act mandate written working conditions, filed Work Rules for larger employers, strict overtime controls and one of the world’s toughest tests for dismissal — and most of these cannot be contracted away. If you also employ people in the Emirates, our UAE payroll and WPS services keep that side compliant while you apply Japan’s rules here — the two systems diverge sharply on income tax, social insurance, severance and wage protection.

This guide walks through what a compliant Japanese contract discloses, who the LSA and Labor Contract Act protect, how social and labour insurance and payroll deductions work, and how overtime, notice and dismissal must be handled — then closes with a practical Japan-versus-UAE comparison for employers building teams in both markets. Country-specific figures that change frequently are flagged [VERIFY] so you confirm the current number with Japan’s Ministry of Health, Labour and Welfare (MHLW) before relying on it.

Is a written employment contract required in Japan?

Written terms are effectively mandatory, even if a single signed document is not. Under the Labor Standards Act, when hiring an employer must clearly state certain working conditions in writing — the contract term, place of work and duties, working hours and breaks, wages and pay dates, and the rules on retirement and dismissal. These particulars may be delivered on paper or, with the employee’s consent, electronically. Failing to provide them is a breach of the LSA.

In practice, Japanese employers issue either a written employment contract (roudou keiyakusho) or a written notice of working conditions (roudou jouken tsuuchisho), often both, and back them with the company Work Rules. A contract is the first line of defence: it fixes salary, hours, probation and the retirement-allowance treatment before a disagreement arises, rather than leaving them to be argued afterwards under Japan’s demanding dismissal rules.

The controlling principle is that a contract cannot fall below the law or below the Work Rules. Where a clause offers less than the LSA minimum — or less than the Work Rules — it is void to that extent and the higher standard applies. Bilingual (Japanese and English) contracts are common for foreign-invested employers, but the Japanese-language terms typically govern.

What must a Japanese employment contract disclose?

The LSA splits disclosure into items that must always be stated in writing and items that must be stated only if the employer has a policy on them. The table below sets out the essentials that a compliant contract or notice of working conditions must cover.

Beyond these, employers commonly document retirement allowance, bonuses, allowances, and welfare matters (which must be stated in writing only where the employer has a rule on them), plus confidentiality, IP assignment and any restrictive covenant. Getting the mandatory items right at the outset avoids the most common source of disputes: ambiguity about what was actually agreed.

Are Work Rules (shuugyou kisoku) required in Japan?

Yes, above a size threshold. An employer that ordinarily employs 10 or more workers must prepare Work Rules (shuugyou kisoku), cover the mandatory topics, hear the opinion of a representative of the workforce, and file the Work Rules with the Labor Standards Inspection Office. The Work Rules must also be made known to employees. Smaller employers are encouraged, but not required, to adopt them.

Work Rules matter far beyond box-ticking: they form part of the working conditions and, where reasonable and properly notified, their terms bind the employment relationship. They typically cover working hours and shifts, wages and pay dates, promotion and transfer, discipline and grounds for dismissal, retirement age and retirement allowance, and health and safety. Because an individual contract cannot undercut the Work Rules, keeping the two consistent is essential.

Confirm the current threshold and filing procedure before deciding Work Rules are not needed, as the count includes most categories of worker at the workplace [VERIFY]. A mismatch between an individual contract and filed Work Rules is a frequent and avoidable source of disputes.

Who is protected by the Labor Standards Act and Labor Contract Act?

Two statutes do most of the work. The Labor Standards Act (LSA) sets the minimum floor — hours, overtime, leave, notice, wage-payment rules — and applies to essentially all employees, backed by the Labor Standards Inspection Office and criminal penalties for serious breaches. The Labor Contract Act governs the contractual relationship itself, including the doctrine that makes an unreasonable dismissal void and the five-year conversion rule for fixed-term staff.

The practical upshot is that Japanese employment is heavily regulated in the employee’s favour, and the individual contract sits on top of — and cannot undercut — both the statutes and the Work Rules. When in doubt about whether a term is enforceable, the safe assumption is that the more protective standard prevails [VERIFY] the current provisions with MHLW.

What types of employment contracts exist in Japan?

Japan recognises several contract structures, and the choice affects security, benefits and the five-year conversion right. The most common are permanent (seishain) employment, fixed-term contracts, part-time work, dispatch (haken) workers supplied by an agency, and genuine independent contractors who fall outside employment law.

The five-year rule is the one foreign employers most often miss: keep an employee on successive fixed-term contracts whose total continuous term exceeds five years, and they may apply to convert to an indefinite contract, which the employer cannot refuse. Misclassifying an employee as a contractor to avoid insurance and benefits is equally risky — Japanese authorities look at the reality of the relationship, not the label. This mirrors the UAE choice between a MOHRE employment contract and a freelancer engagement, which our payroll team helps structure correctly.

What are the minimum wage and working-hours rules in Japan?

Japan sets a regional (prefectural) minimum wage that is revised each year, alongside some industry-specific minimums; where both apply, the higher rate governs. Statutory working time is 40 hours per week and 8 hours per day, and overtime is lawful only if the employer has filed a “36 Agreement” (named after Article 36 of the LSA) with the Labor Standards Inspection Office.

Minimum wages vary by prefecture and have been rising, with the national weighted average around the ¥1,000-per-hour mark in recent years [VERIFY] the current figures for the relevant prefecture. Under the Work Style Reform rules, overtime is capped at generally 45 hours per month and 360 hours per year, with tightly limited special-circumstance exceptions and hard ceilings above that. Overtime pay carries a premium of at least 25%, rising for very long monthly overtime, with about 35% for holiday work and an extra 25% for night work (typically 10pm–5am), and these premiums can stack [VERIFY] the exact rates.

How do social insurance and payroll deductions work in Japan?

Japanese payroll runs through two systems. Social insurance (shakai hoken) covers health insurance and Employees’ Pension, shared roughly 50/50 between employer and employee. Labour insurance (roudou hoken) covers employment insurance and workers’ accident compensation insurance, where the accident-compensation premium is paid entirely by the employer and employment insurance is shared. Employers also withhold national and local income tax from salary under a PAYE-style system, and long-term care insurance applies to employees aged 40 and over.

Worked example: cost of a local hire

Assume an employee on a monthly salary of ¥400,000. Beyond gross pay, the employer owes its share of health insurance, Employees’ Pension and employment insurance plus the full workers’-accident premium — together commonly adding on the order of 15% of salary [VERIFY] to the employer’s cost. The employee, in turn, has their own insurance shares plus income and residents’ tax withheld. So a ¥400,000 salary might cost the employer roughly ¥460,000 [VERIFY] per month before bonuses and benefits, while the employee’s net is lower after deductions. The exact rates depend on prefecture, age and the health-insurance society and must be confirmed [VERIFY] — but the shape matters: budget employer insurance on top of gross, and remember any promised retirement allowance accrues separately.

What annual paid leave and statutory leave apply in Japan?

Employees earn statutory annual paid leave that grows with tenure. An employee who completes six months of continuous service with at least 80% attendance is entitled to 10 days of paid leave, increasing with each further year up to a statutory maximum of 20 days (reached at six and a half years). Since the Work Style Reform, employers must ensure employees take at least five days of their annual paid leave each year.

Unused annual paid leave generally carries over for a limited period before it lapses, and family-leave schemes are periodically enhanced — so confirm the current day-counts, carry-over rules and eligibility before writing them into a contract [VERIFY]. Contractual leave can always exceed the statutory floor, but never fall below it.

What notice period and severance apply in Japan?

Two points are essential. First, notice: an employer must give at least 30 days’ advance notice of dismissal, or pay 30 days of average wages in lieu (the dismissal-notice allowance). Second, there is no universal statutory severance payment in Japan — unlike Korea or the UAE. However, a retirement allowance (taishokukin) is very common, and where it is promised in the Work Rules or the contract it becomes a binding, enforceable obligation.

Because retirement allowance is contractual/customary rather than statutory, its size and eligibility depend entirely on the Work Rules or contract — typically scaling with years of service and final salary. If your scheme promises it, budget for it as an accruing liability; if it does not, be clear in the contract that none is payable, to avoid a later dispute [VERIFY] the treatment against your Work Rules.

How do you terminate employment lawfully in Japan?

Japan has some of the strongest dismissal protection in the world. Under the Labor Contract Act, a dismissal is void if it lacks objectively reasonable grounds and is not regarded as appropriate in general societal terms — the “abuse of the right of dismissal” doctrine. So even where the 30-day notice is given, a dismissal without solid, well-evidenced grounds can be overturned.

For redundancy (seiri kaiko), courts apply a demanding four-factor test: genuine business necessity, real efforts to avoid dismissal (redeployment, cost-cutting), reasonable and objective selection of who is dismissed, and a proper, consultative procedure. The practical routes to end employment are therefore: dismissal with notice and well-documented just cause; redundancy meeting the four-factor test; and, most commonly in practice, mutual agreement (a negotiated resignation), which sidesteps the litigation risk of a contested dismissal. Fixed-term contracts may also end on lawful expiry, subject to the non-renewal (yatoi-dome) protections.

How does hiring a foreign employee in Japan differ?

A non-Japanese must hold an appropriate Status of Residence (zairyuu shikaku) that permits the work in question before employment begins. The status depends on the role and qualifications, and for most hires the employer first supports a Certificate of Eligibility (COE) application, which the employee then uses to obtain the visa. Working outside the scope of one’s status of residence is a serious violation for both parties.

Status-of-residence categories, criteria and quotas are adjusted periodically, so treat any specific requirement as provisional until checked with the Immigration Services Agency of Japan [VERIFY]. Foreign employees are generally still enrolled in the applicable insurances and pay Japanese tax on Japan-sourced employment income, subject to any tax-treaty relief. This contrasts with the UAE, where work authorisation runs through MOHRE (or the free-zone authority) and there is no personal income tax on salary — the subject of the comparison below.

Japan vs UAE: what changes when you hire in the Emirates?

Japan and the UAE are both attractive bases, so companies often build teams in both. But the compliance machinery is very different, and applying Japanese habits to a UAE hire (or vice versa) leaves gaps. If you employ people in the Emirates, our UAE payroll and WPS setup handles the local mechanics; here is what actually differs.

Three differences matter most day to day. First, the UAE has no personal income tax and no pension for expatriates, so there is no monthly PAYE withholding or social-insurance deduction on an expat salary — instead an end-of-service gratuity accrues and is paid on exit, and only UAE and GCC nationals join GPSSA. Second, UAE salaries must flow through WPS, a MOHRE-monitored transfer system, and non-compliance can block new work permits. Third, dismissal in the UAE, while regulated, does not carry Japan’s abuse-of-dismissal-right hurdle. On the corporate side, employers should also keep UAE corporate tax and, where turnover crosses the threshold, VAT in view. If you’re standing up a UAE entity to employ people, our company incorporation team and payroll specialists set the whole stack up correctly.

Common employment-contract mistakes to avoid in Japan

The disputes we see almost always trace back to a handful of avoidable drafting and process errors. Fixing these at the contract stage is far cheaper than a contested dismissal later.

• No written working conditions — the baseline compliance failure; issue the mandatory written particulars (on paper or, with consent, electronically).
• Contract that conflicts with the Work Rules — the more protective standard wins; keep the individual contract and filed Work Rules consistent.
• Overtime without a 36 Agreement — unlawful regardless of the contract; file the agreement and respect the 45/month, 360/year caps [VERIFY].
• Ignoring the five-year fixed-term rule — rolling successive fixed terms past five years total gives the employee a right to convert to permanent status.
• Assuming notice is enough to dismiss — without objectively reasonable, socially acceptable grounds a dismissal can be void; consider mutual agreement instead.
• Copy-pasting a foreign template — a UAE contract routed through WPS with a gratuity clause is not a Japanese contract with Work Rules, the 36 Agreement and social insurance; use the right template for each jurisdiction.
