Japan has one of the most sophisticated, most demanding labor markets in the Asia-Pacific. Its rigid employment framework, mandatory social insurance requirements, and strict contract rules mean that missteps in hiring are not just costly; they can expose your business to serious legal liability.
For US companies looking to build a Japan team without registering a local entity, understanding what is an employer of record is the first step. Using one in Japan is the fastest, most compliant route to market.
What is an Employer of Record in Japan?
Japan’s employment law landscape is shaped by the Labour Standards Act (労働基準法, LSA), the Labour Contract Act (労働契約法), and the Industrial Safety and Health Act. Together, these laws impose significant obligations on employers: written contracts, mandatory social insurance enrollment, strict fixed-term contract limits, and robust employee protections that make dismissal a serious compliance matter.
An Employer of Record (EOR) in Japan is a third-party entity that becomes the legal employer for your Japan-based workers. The EOR employs workers under its own registered Japanese legal entity, issuing compliant contracts, processing payroll in JPY, handling all tax withholding, enrolling employees in mandatory insurance schemes on day one, and managing every statutory obligation on your behalf.
You retain full operational control: you direct the work, set role requirements, and manage performance. The EOR carries all legal employer liability under Japanese law.
How EOR works in Japan
When you engage an EOR for Japan hiring, the process is structured and fully managed:
- You define the role, compensation, and start date.
- The EOR generates a compliant Japanese employment contract, including the mandatory Working Conditions Notice (労働条件通知書) required under the LSA.
- The employee signs electronically. The EOR handles all required disclosures.
- The EOR enrolls the employee in all mandatory insurance schemes on day one: Health Insurance (健康保険), Employees’ Pension Insurance (厚生年金保険), Employment Insurance (雇用保険), and Workers’ Accident Compensation Insurance (労災保険).
- Monthly payroll runs in JPY, with all withholding tax calculations, insurance deductions, and statutory filings handled by the EOR.
- At year-end, the EOR performs the mandatory year-end tax adjustment (年末調整) for every employee.
When to use an EOR in Japan
An EOR is the right solution when you want to hire in Japan before, or instead of, setting up a Kabushiki Kaisha (KK) or Godo Kaisha (GK). It is also the correct choice when speed to hire matters, when you are testing the Japanese market before committing to a full subsidiary structure, or when your team size does not justify the cost and overhead of local entity registration.
How EOR works in Japan: Step by step
Hiring through an EOR in Japan follows a clear, managed process. Here is how it works end-to-end with Multiplier’s employer of record services, from contract to first payroll run:
Step 1: Define the role and compensation
Share the job title, salary, and intended start date with Multiplier. Multiplier advises on local salary benchmarks, statutory minimums, and any relevant allowances such as commuter benefits.
Step 2: Generate a compliant contract
Multiplier generates a Japanese-language employment contract covering all mandatory terms under the LSA: working hours, compensation, leave entitlements, overtime rules, and termination procedures. The mandatory Working Conditions Notice (労働条件通知書) is included.
Step 3: Employee reviews and signs
The employee signs electronically via Multiplier’s platform. All required legal disclosures are handled at this stage.
Step 4: Social insurance enrollment
On the employee’s first day, Multiplier enrolls them in all four mandatory insurance funds. Enrollment filings go directly to the Japan Pension Service (日本年金機構) and the Public Employment Security Office (ハローワーク).
Step 5: Payroll configuration
Multiplier sets up payroll in JPY, applying the correct income tax withholding table (源泉徴収税額表), insurance contribution rates, and any applicable allowances.
Step 6: Monthly payroll processing
Multiplier runs payroll each month, submits all required statutory reports, and delivers electronic payslips to employees.
Step 7: Year-end and ongoing compliance
Multiplier handles the annual year-end adjustment (年末調整), monitors for changes in statutory rates, and manages all ongoing HR administration for the duration of employment.
Full onboarding is completed in under 48 hours. Contract generation takes under five minutes.
Japan employment laws you need to know
Japan’s employment compliance framework is among the most detailed in Asia-Pacific. The following laws and requirements apply to every employer operating in Japan, including those hiring through an EOR.
Labour Standards Act (労働基準法)
The LSA is the foundation of Japanese employment law. It governs written contract requirements, working hours, overtime limits, annual leave entitlements, payroll frequency, and termination procedures. Key requirements:
- Written employment contracts are mandatory. Every contract must specify working hours, compensation, leave entitlements, overtime rules, work location, and termination notice periods.
- The mandatory Working Conditions Notice (労働条件通知書) must be issued to every employee at the start of employment.
- Payroll must be paid at least once per month on a fixed date. Most employers pay between the 25th and the last day of the month.
- Payroll records must be retained for five years.
Labour Contract Act (労働契約法) and fixed-term contract rules
The Labour Contract Act introduced the 無期転換ルール (indefinite-term conversion rule) in 2013. Under this rule, employees who have worked under fixed-term contracts for a cumulative total of five or more years with the same employer have the right to request conversion to an indefinite-term contract. Key contract limits:
- Fixed-term contracts are capped at three years per contract (or five years for highly skilled specialists and senior professionals).
- Once an employee exercises the conversion right, the employer must comply by the start of the next contract period.
- Failing to manage these conversion triggers correctly is one of the most common compliance failures for foreign companies hiring in Japan.
36 Agreement (三六協定) and overtime
Overtime work in Japan is only legal when the employer and employee representatives have entered into a written 36 Agreement (三六協定) with the Labour Standards Inspection Office. Without this agreement, requiring overtime is a violation of the LSA. Under a standard 36 Agreement, overtime is capped at 45 hours per month and 360 hours per year. A Special 36 Agreement can authorize up to 100 hours of overtime in a single month, but only under specific conditions.
Overtime pay rates:
- Standard overtime: 25% above the regular hourly rate
- Work on statutory days off: 35% above the regular hourly rate
- Late-night work (10 PM to 5 AM): 25% above the regular hourly rate (stackable with overtime premium)
Annual leave requirements
Japan’s annual leave law (有給休暇) grants employees a minimum of 10 days of paid leave after six continuous months of employment, provided the employee has worked at least 80% of all scheduled working days. Leave entitlement scales with tenure, reaching a maximum of 20 days per year after 6.5 years of service.
Since April 2019, the 2018 Work Style Reform Act (働き方改革関連法) requires employers to ensure employees actually take at least five days of paid leave per year. Failure to comply results in fines of up to JPY 300,000 per employee per violation.
Dismissal protections
Japan’s dismissal standards are strict. Under the Labour Contract Act, a dismissal is only legally valid when there is an objectively reasonable cause, and the dismissal is considered appropriate by general social standards (社会通念上相当). Courts apply this test rigorously.
- Notice period: A minimum of 30 days’ advance notice is required, or 30 days of average wages paid as a dismissal allowance (解雇予告手当) in lieu of notice.
- Performance-based dismissal requires documented prior warnings, improvement opportunities, and evidence of reassignment attempts.
- Mass redundancies (整理解雇) are subject to Japan’s four-part court-established test: genuine business necessity, sincere efforts to avoid layoffs, fair selection criteria, and good-faith consultation with employees.
Parental leave
Japan provides some of the most generous statutory parental leave in Asia:
- Maternity leave (産前産後休業): 14 weeks total: six weeks prenatal and eight weeks postnatal. The postnatal portion is mandatory.
- Childcare leave (育児休業): Either parent may take childcare leave until the child turns one year old, extendable to 18 months in certain situations.
- Paternity leave (産後パパ育休): As of April 2022, fathers are entitled to a special four-week leave within the first eight weeks after birth. Benefit payments during leave are funded through Employment Insurance at approximately 67% of pre-leave salary for the first six months.
Work permits for foreign nationals
Foreign nationals require a valid status of residence that authorizes the type of work they are performing. The most common categories for professional employment are:
- Engineer/Specialist in Humanities/International Services (技術・人文知識・国際業務): Covers IT, finance, marketing, and international business roles.
- Highly Skilled Professional (高度専門職): A points-based visa offering expedited permanent residency for highly qualified workers.
- Intra-Company Transferee (企業内転勤): For employees transferring from an overseas parent or affiliate.
Employers or their EOR must file a Certificate of Eligibility (在留資格認定証明書) with the Immigration Services Agency before the visa can be issued. Processing typically takes one to three months. See the Japan work visa guide for full details on each category and application requirements.

Japan payroll and social contributions
Japan’s payroll obligations involve multiple government authorities, interlocking contribution rates, and a year-end reconciliation process that applies to every employee. Getting this right on every payroll run is non-negotiable. See Multiplier’s Japan payroll guide for a full breakdown of calculation rules, deadlines, and filing requirements.
Personal income tax (所得税)
Japan uses a progressive national income tax structure, with rates ranging from 5% on taxable income below JPY 1.95 million to 45% on income exceeding JPY 40 million. A separate inhabitant tax (住民税) of approximately 10% is levied at the local government level.
Employers withhold national income tax monthly using the withholding tax table (源泉徴収税額表) and perform an annual year-end adjustment (年末調整) in December to true up each employee’s actual tax liability. The year-end adjustment is mandatory and applies to all employees. It is not optional or elective.
Social insurance contributions
Japan’s social insurance framework (社会保険) covers four mandatory funds. Employer and employee contribution rates for 2024 are as follows:
Insurance fund | Employer rate | Employee rate |
Health Insurance (健康保険) | Approx. 4.99%–5.23% | Approx. 4.99%–5.23% |
Employees’ Pension Insurance (厚生年金保険) | 9.15% | 9.15% |
Employment Insurance (雇用保険) | 0.95% (general industry) | 0.6% |
Workers’ Accident Compensation (労災保険) | 0.2%–8.8% (industry-dependent) | 0% |
Health Insurance rates vary by prefecture and insurer. Figures reflect 2024 standard rates as published by the Japan Pension Service and the Association Kenpo.
Total employer contributions typically fall between 14% and 16% of gross salary.
Enrollment requirements
- Health Insurance and Employees’ Pension Insurance: Mandatory for all full-time employees and part-time employees working 30 or more hours per week. Enrollment must be completed on day one of employment.
- Employment Insurance: Mandatory for employees working 20 or more hours per week on a contract expected to last 31 days or more.
- Workers’ Accident Compensation Insurance: Covers all employees automatically; the full premium is paid by the employer.
Multiplier handles all enrollment filings directly with the Japan Pension Service (日本年金機構) and the Public Employment Security Office (ハローワーク) on day one. Payroll is processed via Multiplier’s global payroll platform, which automates all withholding calculations, contribution filings, and year-end adjustments.
Payslips and records
Employers are not legally required to issue a payslip in Japan, but doing so is standard practice. Multiplier provides electronic payslips to every employee. Payroll records must be retained for five years under the LSA.
Why Multiplier for EOR in Japan
Multiplier is built specifically for the challenge US companies face when hiring in Japan: deep compliance obligations, a language barrier in contract and statutory documentation, and a market where errors are costly and hard to reverse.
Owned entity: no third-party subcontracting
Multiplier owns its legal entity in Japan. This matters because it means there is a single chain of legal accountability for every hire. Some EOR providers subcontract local employment to a third-party partner in Japan, which introduces an additional layer of legal risk and potential inconsistency in compliance standards. With Multiplier, you are dealing with one entity, one compliance team, and one platform.
Compliance depth that competitors miss
Japan’s compliance requirements are highly specific and change regularly. Multiplier’s Japan compliance team tracks amendments to the LSA, updates to social insurance rates, changes to the 36 Agreement framework, and shifts in immigration policy. This is not a generalist global compliance team applying a one-size-fits-all approach. It is dedicated to country expertise.
Transparent, flat-fee pricing
Multiplier offers flat monthly pricing per employee with full total cost of ownership (TCO) transparency: no per-transaction fees, no hidden setup charges, and no variable pricing that makes budgeting difficult. This is a meaningful differentiator against EOR providers that use per-employee variable pricing models that obscure the true cost of a Japan hire.
API-first integrations
Multiplier’s platform connects via API to major HRIS, payroll, and time-tracking tools. This means your Japan employment data flows directly into your existing systems without manual data entry or disconnected spreadsheets. This integration capability is particularly valuable for US-headquartered companies managing a distributed global workforce across multiple platforms.
Speed and ease of onboarding
Contract generation in under five minutes. Full employee onboarding, including social insurance enrollment, is completed in under 48 hours. For US companies accustomed to long Japan market-entry timelines, this is a material operational advantage.

Japan-specific compliance: What most EOR providers get wrong
Japan’s compliance requirements are not just detailed. They are also highly specific in ways that generic EOR platforms frequently handle incorrectly. If you are evaluating EOR providers for Japan, these are the compliance areas that separate providers with genuine Japan expertise from those applying a template approach.
Fixed-term contract conversion tracking
The 無期転換ルール (indefinite-term conversion rule) requires employers to track cumulative fixed-term contract durations for every employee and proactively manage the five-year conversion trigger.
Many EOR providers do not have automated systems to track this across multi-year engagements. Missing the conversion deadline exposes the employer to a mandatory conversion obligation and potential retroactive liability. Multiplier tracks these triggers automatically and initiates the conversion process within the platform before the deadline is reached.
Day-one social insurance enrollment
Japan mandates enrollment in all four statutory insurance funds on the employee’s first day of work, not within a grace period, not after the first payroll run. Late enrollment filings trigger penalty interest and can result in retroactive contribution demands going back to the date of hire.
EOR providers that batch enrollment filings or process them on a weekly or monthly cycle are out of compliance with Japanese law for Japan-specific hiring. Multiplier processes day-one enrollment filings as a standard step in the onboarding workflow.
36 Agreement and overtime compliance
Running overtime for Japan-based employees without a valid 36 Agreement in place is a criminal violation of the LSA, not just an administrative error. Most EOR providers do not advise clients on the 36 Agreement requirement or help structure it. Multiplier’s Japan compliance team ensures that every employment setup includes the correct 36 Agreement framework, and that overtime authorization is properly documented before it is incurred.
Year-end adjustment (年末調整) accuracy
The 年末調整 is a mandatory annual process in which the employer reconciles each employee’s actual tax liability against the amounts withheld throughout the year. It is not a simple payroll run. It requires collecting employee deduction certificates, recalculating income tax using the actual year-end figures, and issuing corrected withholding amounts before the December payroll.
EOR providers that lack dedicated Japan payroll teams frequently make errors in this process, resulting in under- or over-withholding that employees then have to resolve directly with the tax authorities. Multiplier’s Japan payroll team runs 年末調整 as a structured, validated process for every employee on payroll.
Japanese-language contract compliance
Employment contracts in Japan must be issued in Japanese. The Laboring Conditions Notice (労働条件通知書) must be in Japanese. EOR providers that generate contracts only in English, or that offer Japanese as an optional add-on are not meeting the legal standard. All contracts and notices generated through Multiplier for Japan are in compliant Japanese, with English translations provided for your reference.
EOR vs setting up an entity in Japan
Setting up a legal entity in Japan is viable for companies planning long-term, large-scale operations. For most US companies entering Japan for the first time or building a small distributed team, it is slower, more expensive, and more complex than hiring through an EOR. Here is a direct comparison:
Factor | EOR (via Multiplier) | KK/GK subsidiary |
Local entity required | No | Yes |
Time to first hire | Under 48 hours | Two to four months |
Setup cost | No setup fees | USD 3,000–10,000+ |
Compliance owner | Multiplier | Your company |
Statutory filing management | Fully managed | Your responsibility |
Flexibility to exit | High: offboard via EOR | Low: entity dissolution required |
Permanent establishment risk | Mitigated | Managed by your legal team |
Best for | Market entry, small teams, speed | Established large-scale operations |
For companies that have already established a Japan entity and want HR co-management support, a Japan PEO arrangement may be appropriate. But if you do not yet have a local entity, an EOR is the correct structure. Multiplier acts as the legal employer under its own owned Japanese entity, eliminating the need for you to register, staff, and maintain a local company.
