Japan Employment Law Guide for Foreign Employers

Japanese employment law is not contained in one statute. A foreign employer usually needs to read several Acts together: the Labor Standards Act for minimum working conditions, the Industrial Safety and Health Act for workplace safety and health systems, equality and harassment statutes for workplace treatment, and the Employment Contract Act for contract and dismissal rules. This guide links the employment-law articles on this site and explains which statute to check first for each issue.

Minimum Working Conditions

Start with the Labor Standards Act when the issue concerns wages, working hours, days off, overtime, paid annual leave, Work Rules, or labor inspection.

Labor Standards Act: Hours, Wages, and Work Rules explains the statutory definitions of Worker, Employer, Wages, and Average Wage. It also covers labor-contract indication, dismissal notice, wage payment, the forty-hour week and eight-hour day rules, rest periods, weekly days off, overtime agreements, premium wages, paid annual leave, maternity-related protections, Work Rules, and Labor Standards Inspector powers.

This statute supplies many baseline rules, but it does not answer every employment question. For example, a fixed-term renewal issue may require the Employment Contract Act, and workplace safety systems require the Industrial Safety and Health Act. If a rule concerns a form, detailed threshold, or administrative procedure, subordinate regulations may also be needed.

Safety and Health Management

Use the Industrial Safety and Health Act when the issue concerns workplace safety systems, hazard prevention, health examinations, stress checks, safety education, chemical information, or labor inspections concerning safety and health.

Industrial Safety and Health Act: Workplace Duties explains the statutory purpose, Industrial Accident definition, Business Operator duties, and workplace roles such as General Safety and Health Manager, Safety Officer, Health Officer, Industrial Physician, Operations Chief, and Safety and Health Committee. It also explains hazard-prevention measures, worker cooperation duties, safety and health education, work environment measurement, medical examinations, and inspection powers.

This Act often points to Cabinet Orders and Ministry of Health, Labour and Welfare Orders for workplace size thresholds, industry categories, technical measures, and health-examination details. A general article can identify the statutory duty, but implementation usually requires checking those subordinate rules.

Equality, Pregnancy, and Harassment

Workplace equality and harassment measures are split across several statutes. The starting point depends on the protected issue and the type of workplace conduct.

Equal Employment Opportunity Act: Gender and Work covers sex discrimination in recruitment, hiring, assignment, promotion, training, welfare benefits, retirement, dismissal, and contract renewal. It also covers pregnancy- and childbirth-related disadvantageous treatment, sexual harassment measures, maternity-health measures, dispute assistance, mediation, administrative guidance, and publication of employer names in specified cases.

Labour Policy Act: Employment Stability and Harassment covers broader labor-policy measures, foreign-worker employment notifications, treatment-work support, and workplace harassment measures based on a superior relationship. Its harassment provisions require employment-management measures such as consultation systems and appropriate responses, while also prohibiting disadvantageous treatment because a worker sought consultation or cooperated with fact confirmation.

Do not merge these statutes into one generic "harassment law." Each article has its own trigger, protected conduct, employer duty, dispute route, and administrative tool.

Employment Contracts, Work Rules, and Dismissal

Use the Employment Contract Act when the issue concerns contract formation, changes to working conditions, Work Rules as contract terms, transfers, discipline, dismissal, fixed-term contracts, or conversion to indefinite-term employment.

Employment Contract Act: Work Rules and Fixed Terms explains the Act's basic principles, including equality of Worker and Employer, good faith, work-life harmony, and safety consideration. It then covers how labor contracts are formed, how Work Rules can become contract terms, and when a disadvantageous Work Rule change can affect existing labor contracts.

The same article explains Article 14 on secondment, Article 15 on discipline, Article 16 on dismissal, Article 17 on fixed-term contracts during the contract period, Article 18 on indefinite-term conversion after more than five years of total fixed-term contract periods, and Article 19 on refusal to renew fixed-term contracts. These provisions state statutory standards; applying them to facts is a separate analysis.

Foreign Workers and Employment Administration

Foreign-worker employment touches labor law, immigration status, social insurance, tax, and workplace management. The employment-law starting point for notifications and employment-management support is the Labour Policy Act.

The Labour Policy Act article explains Article 28, which requires an Employer to confirm and notify the Minister of Health, Labour and Welfare of specified matters when newly employing a foreign national or when a foreign national leaves employment. It also explains Article 7's employer duty to endeavor to improve employment management for foreign nationals and support reemployment in specified cases.

Those provisions do not replace immigration law. They are employment-policy and notification provisions within the labor-law framework. If the question concerns status of residence, permitted activities, or immigration procedures, the Immigration Control and Refugee Recognition Act and Immigration Services Agency materials must also be checked.
