How to Create Compliant Work Rules (就業規則) in Japan, Step‑by‑step Procedure (2026 Update)

Last updated: 23 June 2026

Every employer in Japan that regularly employs ten or more workers is legally required to prepare written work rules (就業規則, shūgyō kisoku) and file them with the competent Labour Standards Inspection Office. Understanding how to create work rules in Japan is essential for HR managers, in‑house counsel and foreign parent companies establishing or expanding a Japanese subsidiary. The obligation arises under Articles 89–92 of the Labour Standards Act, which prescribe the mandatory content, the employee‑opinion procedure, the filing and posting requirements, and the rules governing subsequent amendments.

This guide walks employers through each stage of the process, from eligibility assessment and drafting through to employee consultation, filing, multilingual distribution and ongoing recordkeeping, incorporating the April 2026 MHLW administrative form revisions and the strengthened guidance on e‑filing and workplace‑environment documentation for foreign staff.

Overview of the Process and Who It Applies To

Work rules in Japan function as the internal employment regulation for a workplace. They set out binding terms on working hours, wages, leave, discipline, dismissal and other conditions that apply uniformly to all employees at an establishment. Under Article 89 of the Labour Standards Act, any employer with ten or more regular employees at a single workplace must prepare work rules and submit them to the Labour Standards Inspection Office that has jurisdiction over that workplace.

The end‑to‑end process follows a consistent sequence: draft the rules, solicit the opinion of a worker representative, finalise and file the rules with the Labour Standards Inspection Office, post or distribute the rules so every employee can access them, and maintain records of each step. Since April 2026, the MHLW has revised its administrative submission forms and reinforced expectations around e‑filing readiness and multilingual documentation for workplaces employing foreign nationals. Employers creating or updating work rules Japan‑wide should confirm they are using the current forms before filing.

Eligibility and Work Rules Requirements

The statutory threshold is straightforward: if a workplace regularly employs ten or more workers, work rules must exist. “Regular employees” includes part‑time staff, fixed‑term contract workers and dispatched workers assigned to the establishment, the count is based on the number of people who ordinarily work at the site, not on the number of full‑time equivalents. Even if headcount drops temporarily below ten, an employer that has already filed work rules remains bound by them until they are formally withdrawn or replaced.

Employers below the ten‑employee threshold are not legally compelled to create work rules, but doing so is strongly recommended. Written rules provide legal certainty on disciplinary procedures, dismissal grounds and overtime calculations, all areas where disputes are common and where a Labour Standards Inspection Office investigation may request documentary evidence.

Before beginning the drafting process, confirm the following prerequisites:

• Headcount. Count every person regularly working at the establishment, regardless of employment type.
• Employment categories. Identify whether separate sets of rules are needed for distinct groups (e.g., full‑time, part‑time, fixed‑term, managerial staff). Separate annexes or supplementary rules are permissible and often advisable.
• Collective agreements. Check whether a labour union exists and whether a collective bargaining agreement (CBA) is in force. Work rules may not set conditions below the CBA standard. Where a CBA exists, the union is typically the body whose opinion must be sought under Article 90 of the Labour Standards Act.
• Foreign staff presence. If the workplace employs a significant number of foreign nationals, plan for multilingual translations and evidence of dissemination from the outset, a point emphasised under the April 2026 MHLW guidance.

How to Create Work Rules in Japan, Step‑by‑Step Procedure

The following numbered steps represent the standard procedure for creating compliant work rules and filing them with the Labour Standards Inspection Office. The summary table below shows who is responsible for each step and the typical duration.

Step 1, Conduct Internal Scoping and Gap Analysis

Identify every employment category at the workplace, full‑time, part‑time, fixed‑term, managerial, dispatched, and determine whether a single set of rules will cover all groups or whether supplementary rules are needed. Assess current informal policies, any existing collective agreements, and language requirements for foreign staff. This scoping stage typically takes one to two weeks and should involve HR, in‑house counsel and, where appropriate, an external employment lawyer familiar with local Labour Standards Inspection Office expectations.

Step 2, Draft Mandatory and Optional Clauses

Article 89 of the Labour Standards Act divides work‑rules content into mandatory items (which must always be included) and conditionally mandatory items (which must be included if the employer operates a relevant scheme). The mandatory items are:

• Working hours. Start time, end time, rest periods, days off, shift patterns and leave (including annual paid leave).
• Wages. Calculation method, payment method, closing and payment dates, and rules on wage increases.
• Retirement and dismissal. Retirement age, grounds for dismissal and dismissal procedures.

Conditionally mandatory items include retirement allowance or severance schemes, bonuses, safety and health provisions, vocational training, workers’ compensation supplementary benefits, disciplinary rules and any other conditions applying to all employees. If the employer operates any of these systems, the relevant details must appear in the work rules.

Drafting typically takes one to three weeks. Employers are strongly advised to use model clauses reviewed by a qualified employment lawyer to avoid ambiguity, particularly on overtime calculation, disciplinary procedures and dismissal grounds, which are the provisions most frequently challenged in labour disputes.

Step 3, Solicit the Employee Opinion (意見聴取)

Under Article 90 of the Labour Standards Act, the employer must hear the opinion of one of two parties before filing: either the labour union representing a majority of workers at the establishment, or, where no such union exists, a person representing a majority of workers. This work rules update employee opinion procedure is a substantive legal requirement, not a formality.

The representative must be chosen by a majority of workers through a democratic process (such as a vote or show of hands); the employer may not unilaterally designate the representative. Once selected, the representative reviews the draft rules and provides a written opinion (意見書, ikensho). The opinion does not need to be favourable, the law requires that the employer hear the opinion, not that the employer obtain consent, but it must be documented and attached to the filing.

Best practice is to allow seven to fourteen days for this consultation. Provide the representative with a copy of the full draft, hold a meeting to walk through each section, and record the meeting minutes. If the representative objects to any provision, note the objection in the written opinion and retain the document. This record is essential evidence during any subsequent Labour Standards Inspection Office inspection.

Step 4, Finalise Rules and Obtain Employer Sign‑Off

After receiving the employee opinion, incorporate any revisions the employer agrees to, add a version number and effective date, and obtain sign‑off from senior management. The final version should be in Japanese. Where multilingual work rules 2026 requirements apply (see the 2026 changes section below), prepare translations at this stage. Finalisation typically takes one to three days.

Step 5, File with the Labour Standards Inspection Office

The employer must submit a copy of the finalised work rules, together with the employee opinion document, to the Labour Standards Inspection Office having jurisdiction over the workplace. This is the core work rules filing Labour Standards Inspection Office obligation under the Labour Standards Act. The filing package consists of:

• The completed work rules (Japanese original)
• The written employee opinion (意見書)
• The relevant MHLW submission form, employers should download the April 2026 revised form from the MHLW website to ensure compliance with the current administrative requirements
• A cover letter identifying the employer, workplace address, contact person and the statutory basis for filing

Filing may be done in person at the local office, by post or, where available, via e‑filing. The April 2026 MHLW revisions have expanded e‑filing work rules Japan options, though availability and technical procedures vary by prefecture. Check with the relevant local bureau before submitting electronically for the first time. There is no statutory government fee for filing work rules.

Step 6, Notify Employees and Post the Rules

Under Article 106 of the Labour Standards Act, the employer must make the work rules known to all employees. Acceptable methods include posting the rules in a conspicuous location at the workplace, distributing printed copies, making them available on the company intranet, or providing electronic copies. For workplaces with foreign staff, distributing a translated summary alongside the Japanese original, and recording the distribution via email or signed receipt, satisfies the heightened 2026 MHLW guidance on how to notify work rules Japan workplaces. Notification should occur immediately upon filing.

Step 7, Maintain Records and Schedule the Next Review

Retain the signed employee opinion, the filing receipt from the Labour Standards Inspection Office, and each version of the work rules for the entire period the rules remain in effect. Archive superseded versions for a minimum of five years. Schedule an annual review, or an ad hoc review whenever there is a material change in law, business operations or workforce composition, to ensure the rules remain current.

Required Documents and Information, Work Rules Checklist

The table below consolidates every document the employer should prepare before and during the work rules creation process. Items marked as “mandatory” must be included in the filing; items marked “recommended” are not legally required for filing but are strongly advisable for compliance and inspection readiness.

Ensuring every document in this work rules checklist is prepared and version‑controlled before the filing appointment reduces the risk of queries or requests for supplementary information from the Labour Standards Inspection Office.

Timeline and Key Deadlines for Work Rules in Japan

The Labour Standards Act does not prescribe a single fixed deadline by which work rules must be filed after an employer reaches the ten‑employee threshold, but the obligation is immediate and ongoing, meaning the employer should create, consult on and file the rules without unreasonable delay. The table below sets out realistic time expectations for each phase.

In aggregate, a first‑time creation project, from initial scoping through to filed and posted rules, typically takes four to eight weeks. Employers with complex structures (multiple categories of employees, shift‑work arrangements or a large proportion of foreign staff requiring translations) should plan for the longer end of that range. Labour Standards Inspection Office inspectors may ask to see evidence that rules were filed promptly after the employer reached the ten‑employee threshold, so documenting the project timeline is advisable.

Costs, Fees and Tax Considerations

There is no statutory government fee for filing work rules with the Labour Standards Inspection Office. The primary costs are professional fees for drafting, filing support and translation. The table below provides indicative market ranges.

Professional fees for drafting and review are generally tax‑deductible as ordinary business expenses. Employers should retain invoices and engagement letters as supporting documentation.

What Changes in 2026, MHLW Form Revisions and Multilingual Guidance

The MHLW released revised administrative forms and updated guidance effective April 2026. The key changes relevant to employers creating or updating work rules Japan‑wide are:

• Revised submission forms. The standard notification form used when filing work rules with the Labour Standards Inspection Office has been updated. Employers should download the current version from the MHLW April 2026 forms page before filing. Using an outdated form may result in the filing being returned for correction.
• E‑filing expansion. The April 2026 guidance reinforces the MHLW’s push toward e‑filing. While not yet universally mandatory, more prefectural Labour Standards Inspection Offices now accept electronic submissions, and employers are encouraged to check e‑filing availability with their local bureau.
• Multilingual work rules and evidence of workplace‑environment measures. For workplaces employing foreign nationals, the updated guidance strengthens expectations that employers provide translated versions of key work‑rules provisions (or at minimum a translated summary) and retain evidence of dissemination, such as email distribution records, signed employee receipts or meeting minutes. While full translation of work rules is not strictly mandated for every employer, industry observers expect Labour Standards Inspection Office inspectors to scrutinise workplaces with foreign staff more closely under the 2026 guidance.

Employers should add a “multilingualisation and evidence” sub‑checklist to their filing packet as a practical compliance step.

Common Pitfalls and How to Avoid Them

• Ambiguous overtime, disciplinary or dismissal clauses. Vague language on overtime calculation, grounds for disciplinary action or dismissal procedures is the most common source of labour disputes. Use model clauses reviewed by a qualified employment lawyer. If a clause is challenged, reissue corrected rules following the full employee‑opinion and filing procedure.
• Failing to record the employee opinion. Skipping or informally conducting the employee‑opinion step leaves the employer without the mandatory 意見書 to attach to the filing and exposes the company to inspection findings. Use a template opinion form, keep the signed original and retain meeting minutes.
• No translation or evidence of distribution for foreign staff. Under the strengthened 2026 MHLW guidance, a Labour Standards Inspection Office inspector may ask for evidence that foreign employees were able to understand the rules. Provide translations in relevant languages and document distribution (email logs, signed receipts). If evidence is missing, prepare translations and re‑distribute promptly.
• Filing with an outdated form. The April 2026 MHLW form revision means that pre‑2026 submission forms may be rejected. Always download the current form from the MHLW or local Labour Bureau website immediately before filing. If a filing is returned, correct the form and re‑submit without delay.
• Not reviewing rules after a material change. Work rules must be amended whenever there is a change to working conditions, wage structures or legal requirements. Failing to update and re‑file creates a compliance gap. Schedule an annual review and trigger ad hoc reviews upon any material operational or legal change.
