WTS Energy provides Employer of Record services in Japan for energy, engineering and industrial companies that need to employ local or international professionals without immediately establishing a Japanese entity. We act as the legal employer, manage employment contracts, payroll, statutory deductions, social insurance coordination, immigration documentation and HR compliance, while you manage the employee’s day-to-day technical work.

Japan is a high-value market for LNG, offshore wind, power, hydrogen, grid infrastructure, engineering services and advanced industrial projects. It is also a highly regulated employment environment, with strict rules on working time, overtime agreements, paid leave, social insurance, dismissal, fixed-term contracts and foreign-national residence status.

WTS Energy’s EOR model gives project owners, EPC contractors, developers and technical service companies a controlled way to build teams in Japan. Our workforce specialists and local compliance network help you onboard the right people while reducing the risk of payroll errors, work-status issues and employment-law exposure.

What makes Japan different

Japan rewards careful onboarding, clear work rules, and immigration planning for specialist technical roles where documentation quality is central.

For WTS Energy, our EOR in Japan starts with the operating reality: what the role does, where the person will work, whether immigration is involved, and which payroll or benefit obligations must be visible before mobilisation. That makes the page more than a generic employer-of-record explanation; it is a country-specific hiring route for energy, engineering, and industrial employers.

Key planning themes for Japan:

• Technical talent access.
• Contractor conversion.
• Benefits administration.
• Compliance controls.

Why energy employers use WTS Energy here

Japan rewards employers that prepare carefully. Employment contracts, payroll setup, immigration status, social insurance and work rules need to be aligned before work begins.

With our EOR in Japan, WTS Energy supports companies that need:

• Entity-free hiring for Japan-based technical, commercial or project roles.
• Local and regional HR support for contracts, onboarding, payroll, benefits and offboarding.
• Energy-sector workforce knowledge across renewables, LNG, power, engineering, commissioning and project services.
• Payroll administration for salary, overtime, statutory deductions, annual paid leave and year-end tax processes.
• Immigration coordination for foreign nationals under appropriate work statuses, such as Engineer/Specialist in Humanities/International Services, Highly Skilled Professional or Specified Skilled Worker where relevant.
• Support for mobile workforces moving between Japan, regional project offices, shipyards, fabrication yards, offshore support locations and client sites.
• Practical compliance advice from people who understand how international energy projects operate.

The 2026 employment rulebook in brief

Employment contracts and work rules

Japanese employers must clearly state employment conditions, including wages, working hours, workplace, job duties, holidays, leave, contract terms and termination provisions. For globally mobile energy roles, employers should also address site assignments, travel, overtime approval, confidentiality, intellectual property, data security and safety obligations in the employment contract.

Japanese law permits fixed-term employment but limits employers’ ability to rely indefinitely on repeated fixed-term contracts. When an employer renews fixed-term contracts with the same employee and the total contract period exceeds five years, the employee can request conversion to an indefinite-term contract. Japanese law also generally restricts fixed-term contracts to a maximum of three years, although employers may use terms of up to five years for certain highly specialised workers and employees aged 60 or older.

Minimum wage

Japan sets minimum wages by prefecture. The Ministry of Health, Labour and Welfare’s latest prefectural minimum wage list for fiscal year 2025 applies through much of 2026 until the next annual revisions take effect.

Key 2026 planning points include:

• The national weighted average regional minimum wage is JPY 1,121 per hour.
• Tokyo’s regional minimum wage is JPY 1,226 per hour from October 3, 2025.
• Osaka’s regional minimum wage is JPY 1,177 per hour from October 16, 2025.
• The lowest prefectural rates in the current list are JPY 1,023 per hour in several prefectures.

Energy-sector professional salaries are normally far above statutory minimum wage. Even so, the minimum wage check matters for interns, part-time support, allowances converted to hourly value, and payroll audits.

Working hours, overtime and rest

The general statutory working time limit allows employees to work up to eight hours per day and 40 hours per week. Employers must provide at least 45 minutes of break time when employees work more than six hours and at least one hour when they work more than eight hours. They must also provide at least one day off per week or four days off within a four-week period.

Employers who require overtime or holiday work must conclude a labour-management agreement, commonly known as a 36 Agreement, and file it with the Labour Standards Inspection Office. MHLW guidance generally limits overtime to 45 hours per month and 360 hours per year, although special rules and caps may apply. Employers must pay premium wages of at least 25% for ordinary overtime, 35% for statutory holiday work and 25% for late-night work between 10 p.m. and 5 a.m. When overtime exceeds 60 hours in a month, employers must pay a premium of at least 50%.

For energy projects, employers must account for these requirements when planning commissioning schedules, shutdown support, engineering deadlines and client-site rotations. WTS Energy helps employers structure working hours and approval processes before payroll begins.

Paid leave and statutory leave

Employees who have worked continuously for six months and attended at least 80% of scheduled working days are entitled to annual paid leave. Full-time employees typically start with 10 days, increasing with length of service.

Japan also provides statutory maternity, childcare and family-care protections. Employers must not treat employees unfavourably because they use protected leave rights. For internationally managed teams, these rights need to be built into workforce planning, backfill and project-delivery schedules.

Notice, dismissal and offboarding

Dismissal in Japan requires careful legal and factual review. MHLW guidance states that dismissal may be invalid where it lacks objectively reasonable grounds and is not socially acceptable.

The Labour Standards Act generally requires at least 30 days’ advance notice of dismissal or payment of dismissal notice allowance for the shortfall. This notice rule does not remove the need for a valid reason and a fair process. WTS Energy manages offboarding with local advice so exits are not handled like ordinary commercial contract terminations.

Payroll tax and social insurance

Japan payroll requires withholding and reporting for income tax, local inhabitant tax coordination, social insurance and labour insurance.

For 2026 payroll planning:

• The National Tax Agency publishes the Withholding Tax Guide 2026 and employment-income withholding materials.
• Employees’ Pension Insurance contributions are calculated on standard monthly remuneration and bonuses and are shared equally by employer and employee. The general EPI contribution rate is 18.3%, split 9.15% employee and 9.15% employer.
• Health insurance rates vary by insurer and prefecture. For employees covered by Japan Health Insurance Association arrangements, the rate is set by branch and normally shared by employer and employee.
• Employment insurance rates for fiscal year 2026 are lower than fiscal year 2025. For general businesses, the total rate is 13.5/1000, with 5/1000 borne by the employee and 8.5/1000 borne by the employer.
• Workers’ compensation insurance is employer-funded and varies by industry risk classification.

WTS Energy’s EOR payroll process calculates the employer burden and employee deductions before hiring so project budgets reflect the real cost of employment.

Immigration and work status

Foreign nationals must hold a status of residence that matches the actual work in Japan. A work visa label alone is not enough; the activities performed must remain within the permitted status.

Common work routes include:

• Engineer/Specialist in Humanities/International Services for many professional technical, business and international-services roles.
• Highly Skilled Professional for candidates who meet the points-based criteria and qualify for preferential immigration treatment.
• Specified Skilled Worker for designated industry fields where the worker meets the skills and Japanese-language requirements.
• Intra-company Transferee or Business Manager in narrower cases where the facts support those statuses.

The Ministry of Foreign Affairs explains that a Certificate of Eligibility is normally issued by a regional immigration authority under the Immigration Services Agency before many work visa applications. WTS Energy supports document consistency between the employment contract, role description, salary, work location and immigration filing.

How WTS Energy can support employers here

Japan rewards employers that prepare carefully. Employment contracts, payroll setup, immigration status, social insurance and work rules need to be aligned before work begins.

Our EOR in Japan supports companies that need:

• Entity-free hiring for Japan-based technical, commercial or project roles.

• Local and regional HR support for contracts, onboarding, payroll, benefits and offboarding.

• Energy-sector workforce knowledge across renewables, LNG, power, engineering, commissioning and project services.

• Payroll administration for salary, overtime, statutory deductions, annual paid leave and year-end tax processes.

• Immigration coordination for foreign nationals under appropriate work statuses, such as Engineer/Specialist in Humanities/International Services, Highly Skilled Professional or Specified Skilled Worker where relevant.

• Support for mobile workforces moving between Japan, regional project offices, shipyards, fabrication yards, offshore support locations and client sites.

• Practical compliance advice from people who understand how international energy projects operate.

Managing risk before the first hire starts

Japan is a country where the details of employment administration matter. An EOR structure is valuable because the legal employer must manage payroll, social insurance, working time, leave and immigration correctly from the first month.

Key risks include:

• Misclassification risk where a contractor is actually directed and integrated like an employee.

• Overtime risk where project schedules exceed statutory limits or a 36 Agreement is not in place.

• Payroll risk where social insurance, employment insurance, withholding tax or year-end tax processes are incomplete.

• Immigration risk where the employee’s actual duties do not match their permitted status of residence.

• Dismissal risk where exits are attempted without objectively reasonable grounds and documented process.

• Permanent establishment risk where a Japan-based employee has local authority to negotiate or conclude contracts.

• Fixed-term contract risk where repeat renewals create indefinite-term conversion rights.

WTS Energy delivery model in practice

Before the employee starts

WTS Energy confirms the role, work location, reporting line, salary, expected working hours, contract term, immigration status and project requirements. We prepare compliant onboarding documentation, check payroll and social-insurance assumptions, and define whether overtime approval, travel allowances or site-mobility terms are needed.

For foreign nationals, we review whether the planned duties match the candidate’s residence status and whether a Certificate of Eligibility, change of status or renewal process is required.

Operational employment support

WTS Energy operates payroll, statutory deductions, contribution handling, leave tracking and HR administration. We support contract changes, payroll questions, employment certificates, immigration renewals and project-specific employment letters.

Your team directs the employee’s daily work, technical priorities and performance expectations. WTS Energy remains the legal employer and keeps the employment record aligned with Japanese compliance requirements.

End-of-assignment handling

WTS Energy supports resignation handling, contract expiry, performance exits, redundancy planning and final pay. We coordinate return of property, confidentiality reminders, immigration updates where needed and documentation for any exit that requires local legal review.

Upcoming reforms and planning points

Employers hiring in Japan in 2026 should monitor:

• Social insurance expansion: MHLW states that the monthly wage requirement for certain short-time workers is scheduled to be abolished in October 2026, and company-size thresholds will be reduced in stages from October 2027.
• Pension reforms: MHLW’s 2025 pension reform outline includes changes effective from April 1, 2026 in several areas, with phased implementation for coverage expansion and lump-sum withdrawal payment rules.
• Employment insurance rates: Fiscal year 2026 employment insurance rates are reduced compared with fiscal year 2025, affecting payroll calculations from April 2026.
• Childcare and family-care rules: Revised childcare and family-care obligations introduced in 2025 continue to affect employer information, consultation and flexible-working measures.
• Minimum wage revisions: Japan generally revises prefectural minimum wages annually; the next cycle should be monitored for changes affecting late 2026 payroll.
• Immigration scrutiny: Employers should expect continuing review of whether foreign nationals’ duties match the stated status of residence, especially where work is operational rather than professional or specialised.

WTS Energy monitors these changes and updates employment documentation, payroll settings and immigration planning as the rules evolve.
