Wages, Human Resources, Laws & Regulations How to Set Up a Business in Japan

1. Introduction

Japan is an attractive market for foreign investors because of its strong economy, advanced technology, and highskill workforce. However, establishing a presence there requires a clear understanding of local labor practices, wage standards, and the regulatory framework that governs employment. This guide provides a concise overview of the key HRrelated issues you must consider when setting up a business in Japan.

2. Core Labor Laws You Must Know

2.1 Labor Standards Act (LSA)

The LSA sets the minimum standards for working conditions, including:

• Maximum weekly working hours (typically 40 hours).
• Overtime work must be compensated at a minimum of 25% premium.
• Paid annual leave (minimum 10 days after six months of continuous employment).
• Minimum wage, which varies by prefecture.

2.2 Employment Contracts Act

Employment contracts can be written or oral, but written contracts are strongly recommended. They must clearly state job duties, salary, working hours, and the conditions for termination.

2.3 Equal Employment Opportunity Law (EEO)

The EEO prohibits discrimination based on sex, age, marital status, disability, and other protected characteristics. It also requires companies to set up a workplace environment that prevents harassment.

2.4 Social Insurance System

Employers must enroll workers in four mandatory programs:

• Health Insurance
• Pension (Employees Pension Insurance)
• Unemployment Insurance
• Workers Accident Compensation Insurance

Contributions are shared between employer and employee, typically ranging from 14% to 18% of the salary.

2.5 Labor Union Law

Employees have the right to organize and join unions. While unionlevel collective bargaining is less common than in some countries, employers must negotiate in good faith if a union is recognized.

3. Wage Structure and Minimum Wage

3.1 Minimum Wage

Each prefecture sets its own minimum hourly wage, reviewed annually. As of 2025, the Tokyo minimum is 1,041 per hour, while some rural areas are around 850. Employers must pay at least the regional minimum, regardless of employee status.

3.2 Salary Components

Typical Japanese compensation packages include:

• Base Salary Fixed monthly amount.
• Bonuses (Shgy) Usually paid twice a year (summer and winter) and often amount to 36months of salary.
• Allowances Commute, housing, family, and position allowances.
• Performance Pay Variable component tied to individual or company performance; must be clearly defined in the contract.

3.3 Overtime & Holiday Pay

Overtime rates increase after 60hours per month (35% premium) and after 120hours per month (up to 45%). Work on national holidays must be compensated at least 35% above the regular wage.

4. Hiring Foreign Employees

4.1 Visa Types

The most common work visas for foreign professionals are:

• Engineer/Specialist in Humanities/International Services
• IntraCompany Transferee
• Business Manager (for executives establishing a company)

Each visa requires a certificate of eligibility (COE) issued by the Immigration Bureau before the employee can enter Japan.

4.2 Language Requirements

While Japanese language proficiency is not a statutory requirement, many roles (especially customerfacing) expect at least JLPT N2 level. Providing language training can improve integration and reduce turnover.

4.3 Equal Treatment

Foreign workers are protected by the same labor standards as Japanese employees. The Equal Employment Opportunity Law applies regardless of nationality, so ensure parity in wages, benefits, and working conditions.

5. Setting Up Your HR Infrastructure

5.1 Registering the Company

To hire staff, you must first incorporate a legal entity (Kabushiki Kaisha KK, Godo Kaisha GK, or a branch office). The registration process typically takes 24 weeks and involves:

• Preparing Articles of Incorporation
• Depositing the minimum capital (1 for a KK/GK)
• Filing with the Legal Affairs Bureau
• Applying for a corporate seal (inkan)

5.2 Office Setup and Labor Office Registration

After incorporation, you must register the workplace with the local Public Employment Security Office (Hello Work) and the Labour Standards Inspection Office. This registration is required for socialinsurance enrolment.

5.3 Payroll & Attendance Systems

Most companies use software that handles:

• Monthly payroll calculation, including overtime, bonuses, and tax withholding.
• Socialinsurance premium calculations.
• Timekeeping (shifts, vacation accrual, paid leave).

Popular solutions include SmartHR, Freee, and Money Forward. Many providers also offer compliance updates to keep you aligned with legislative changes.

5.4 Employee Handbook (Rdshgi)

Japanese law requires a clear set of workplace rules (shgy kihon). The handbook should cover:

• Working hours, holidays, and overtime policy
• Dress code and conduct
• Disciplinary procedures
• Safety and emergency protocols

Distribute the handbook to all staff and obtain signed acknowledgment.

6. Compliance Checklist for New Employers

1. Incorporate a legal entity and obtain a corporate seal.
2. Open a corporate bank account and register for tax (Corporate Tax, Consumption Tax).
3. Register the workplace with HelloWork and the Labour Standards Inspection Office.
4. Enroll all employees in the four socialinsurance programs within 5days of hiring.
5. Set up a payroll system that automatically calculates taxes and insurance contributions.
6. Prepare employment contracts that comply with the LSA and Employment Contracts Act.
7. Establish a written employee handbook and have each employee sign it.
8. Ensure minimum wage compliance for each prefecture where you operate.
9. Implement a system for recording working hours, overtime, and paid leave.
10. Provide mandatory workplace safety training (Industrial Safety and Health Act).

7. Common Pitfalls and How to Avoid Them

7.1 Underestimating Payroll Complexity

Japanese payroll includes multiple deductions (income tax, resident tax, pension, health insurance, unemployment insurance, and accident insurance). Using an experienced payroll service or certified accountant mitigates errors and penalties.

7.2 Ignoring Local Minimum Wage Variations

Applying a uniform wage across all locations may breach local minimumwage ordinances. Keep an updated spreadsheet keyed by prefecture.

7.3 Failure to Provide Adequate Documentation

Verbal agreements are not enforceable under Japanese labor law. Always provide written contracts, payslips, and a copy of the employee handbook.

7.4 Misclassifying Workers

Attempting to label fulltime staff as contractors to avoid socialinsurance contributions is illegal and can result in heavy fines.

7.5 Neglecting WorkLife Balance Expectations

Japanese culture values long hours, but the government is pushing for reduced overtime. Implement clear overtime limits and encourage the use of paid leave to stay compliant and retain talent.
