The Labor Bureau (Rodo-Kijun-Kantokusho)

The Labor Bureau Japan system, anchored by the 労働基準監督署 (rōdō kijun kantokusho, "Labor Standards Inspection Office"), is where an employee goes when an employer breaks labor law.¹² A consultation costs nothing, and a formal complaint can force an employer to fix unpaid wages or illegal overtime.³²

Overview

This article is for employees with a labor-law complaint, on any work-permitting status and any contract type.⁴ It covers what the inspection office enforces, what it can compel, what it cannot do, and how to file.

The statutes below are national law and apply identically across Japan.⁴⁵ What varies by office is practical: which foreign languages are available, on which days, and at which counter.⁶

Where it sits in the enforcement chain

The inspection office is the front-line enforcement body for the Labor Standards Act.¹ It operates under the prefectural 都道府県労働局 (todōfuken rōdōkyoku, "prefectural Labor Bureau") within the 厚生労働省 (kōsei rōdōshō, "Ministry of Health, Labour and Welfare (MHLW)") chain.⁵¹

MHLW separates this enforcement track from neighboring tracks.⁵ Hello Work handles placement and employment insurance. The Labor Bureau Employment Environment and Equal Opportunity division handles equal-opportunity and childcare-leave statutes. Courts handle mediation, the Labor Tribunal, and lawsuits.⁵

The entry point for most workers is the 総合労働相談コーナー (sōgō rōdō sōdan kōnā, "Comprehensive Labor Consultation Corner"). Corners sit inside each prefectural Labor Bureau and in inspection offices nationwide, 378 locations in total (as of 2026; confirm current figures with the Ministry of Health, Labour and Welfare).³ Where a suspected Labor Standards Act violation exists, the corner refers the matter to the inspection office or another authority holding administrative-guidance power.³

What the Labor Bureau Enforces

The inspection office handles violations of the Labor Standards Act and related labor-standards statutes.⁵¹ Three groups of violations make up most employee complaints.

Unpaid wages and wage payment violations

Unpaid wages and unlawful wage deductions sit at the center of inspection work.¹² This includes pay below the prefectural minimum and missing overtime premium.¹²

The statutory basis includes Labor Standards Act Article 24, which requires full-amount, in-currency, direct, monthly fixed-date payment, and Article 28, which points to Minimum Wage Act standards.⁴ Article 37 sets the premium-pay duty for overtime, holiday, and night work.⁴

Practitioner sources describe roughly a 3-year window to recover unpaid wages before the claim prescribes, though the underlying prescription text was not directly verified for this article.² File promptly rather than waiting to see whether the employer pays voluntarily.

Illegal overtime and working-hours violations

Excessive working hours form the second group: a missing 36 Agreement, overtime beyond the legal caps, or falsified working-hour records.¹² Refusal to grant annual paid leave falls in this group as well.²

The statutory basis includes Article 32 (the 40-hour week and 8-hour day), Article 36 (overtime only under a filed labor-management agreement within statutory caps), and Article 37 (premium pay).⁴ Annual paid leave itself comes from Article 39.⁴

Dismissal-procedure and working-conditions violations

The third group covers procedure, not the fairness of the dismissal itself.¹ It includes dismissal without the required notice or notice pay, failure to provide a written statement of working conditions, and concealment of industrial accidents or failure to apply for workers compensation.¹

The statutory basis includes Article 15 (the employer must state wages, hours, and other conditions as set by MHLW ordinance), Article 20 (30 days advance dismissal notice or 30 days average-wage payment in lieu), and Article 89 (the duty to draw up and file rules of employment at workplaces with 10 or more workers).⁴ Accident compensation sits in Article 75 and following provisions.⁴

What It Can Compel

The inspection office investigates the employer and orders fixes.¹² It does not negotiate between the parties or award anything to the worker directly.

Records, on-site inspection, and interviews

After a complaint, an inspector reviews it and may visit the workplace unannounced.¹² This on-site visit is called 臨検 (rinken, "on-site inspection").²

The inspector checks the records the statute requires the employer to keep: the worker roster under Article 107, the wage ledger under Article 108, and preserved records under Article 109.⁴ Time records, 36 Agreements, and work rules are tested against the same file.¹²

Corrective orders and follow-up

Where violations are confirmed, the office issues a 是正勧告 (zeisei kankoku, "corrective recommendation").² The order tells the employer what to fix and by when.¹²

The inspector then follows up to confirm compliance within the set deadline.¹ In the practitioner-described flow, back pay arrives because the employer complies, not because the office transfers money.¹²

Criminal referral in serious cases

In serious cases, the office can refer the matter to prosecutors for criminal charges.¹² Practitioner sources describe wage theft, repeated violations, fraud, and accident concealment as the typical triggers, and describe actual referrals as relatively rare.¹²

The penal provisions sit in Chapter XIII of the Act, Articles 117 through 121.⁴ A referral ends the administrative track and starts a criminal one, which is why most cases stop at the correction-order stage.¹²

What It Cannot Do

Knowing the boundary saves a wasted visit.⁵² The inspection office enforces statutory minimums against the employer; it does not settle what the employer owes you personally.⁵²

No reinstatement, damages, or settlement awards

Reinstatement after an unfair dismissal, a settlement payment, and damages for harm suffered are civil remedies.⁵² The inspection office cannot award any of them, even when the underlying violation is clear.²

Those remedies live on a separate track that MHLW lists apart from inspection supervision: civil mediation, the Labor Tribunal, provisional disposition, and the main-action suit.⁵ Practitioner sources compare the tracks as follows (as of 2026-03; confirm current figures with the Ministry of Health, Labour and Welfare).²

Track	Best for	Cost	Practitioner-described pace (as of 2026-03)
Labor Bureau mediation (あっせん)	Negotiated settlement where both sides will talk	Free	About 1 to 2 months; needs employer participation
Labor Tribunal (労働審判)	Dismissal and back-pay claims	Filing fee based on claim	About 2 to 3 months, up to 3 hearings
Civil suit (訴訟)	Large claims, reinstatement	Lawyer plus filing fees	About 6 to 12 months or longer

The pace figures above come from a single practitioner source and were not verified against court publications for this article. Treat them as orientation, not promises.²

Harassment and discrimination routing

Harassment claims go to the Labor Bureau, specifically the Employment Environment and Equal Opportunity division, not the inspection office.⁵² Discrimination claims go to the Labor Bureau or the human-rights bureau.²

The consultation corners accept every field of labor problem from either side: dismissal, non-renewal, transfer, wage cuts, recruitment, bullying and harassment including power harassment, and sexual-orientation and gender-identity matters.³ Consultations are free and need no appointment, and the corner routes each matter to the counter that actually holds power over it.³

How to File a Complaint

The path below runs from the first call to the follow-up check.¹² Each step is voluntary; you can stop after advice, or carry through to a formal filing.

A consultation clarifies whether the facts fit a statute the inspection office enforces.¹² If they fit a different track, the adviser says so and points to the right counter.³⁵

Consultation versus formal complaint (shinkoku)

A phone or in-person consultation gives advice only.² A formal complaint, called 申告 (shinkoku, "formal complaint requesting investigation"), asks the office to investigate and can trigger an inspection.²

You can file in writing or verbally at the office.² One practitioner source gives the filing phrase as "会社が法律に違反しているので、申告したいです" (my company is breaking the law and I want to file a formal complaint).²

A consultation alone does not start an investigation

Advice-only contact leaves no case file behind. Workers who stop after a call have not set enforcement in motion; only a formal shinkoku does that.²

Anonymous information and consultations are accepted by phone or the MHLW online form for initial guidance.¹ A formal written complaint typically requires your name and address, though.¹ The online-form detail comes from a single practitioner source and was not verified against an official form URL for this article.¹

Which office and what to bring

File at the inspection office with jurisdiction over the workplace location, not your home address.¹² The office near home is the wrong counter when the job sits in a different district.¹²

Bring the employment contract, pay slips for as many months as available, work-time records, evidence of the violation, and the residence card.² Work-time records can be the company time card, shift records, or your own log; employer messages, emails, and photos count as evidence.²

Bring records an inspector can test against the ledger

A personal hours log plus pay slips carries more weight than a bare account. Inspectors compare employer records against evidence, so dated records shorten the case.⁴¹²

Advisers can help even when documentation is incomplete.¹ A contemporaneous personal log in a notebook or notes app is specifically useful, and even rough dated estimates help.¹

Typical pace and confidentiality

No official guaranteed timeline is published in the sources consulted for this article.¹² The practitioner-described sequence is review, inspection, correction order with a deadline, follow-up, and possible criminal referral.¹²

Hotline consultations are confidential and do not notify the employer.¹ Where a formal complaint leads to investigation, the office contacts the employer as part of the investigation but does not disclose who filed.¹ Labor Standards Act Article 105 binds inspectors to confidentiality over complainant identity, though the article text itself was not directly verified for this article.⁴¹

Retaliation for filing is a separate violation

The employer cannot fire, demote, transfer, or otherwise disadvantage you for filing. MHLW states that disadvantaging a worker for using the consultation or dispute-resolution system is prohibited by law, so report any retaliation as a fresh violation.⁷²

In a small workplace the employer may still infer who complained from the facts alone.¹ Confidentiality protects your name on paper; it cannot hide the substance of a complaint only one person could have made.¹

Foreign-Language Support Reality

Multilingual entry points exist, but they run on limited days and hours.⁶ Plan around the schedule instead of assuming walk-in English support.

Prefectural consultation corners and advice hotline

The Telephone Consultation Service for Foreign Workers covers 13 languages on dedicated lines, weekdays 10:00 to 15:00 with a midday break, closed December 29 to January 3 (as of 2026-08; confirm current figures with the Ministry of Health, Labour and Welfare).⁶ Each language runs only on specific days: English and several others run weekdays, while languages such as Thai, Indonesian, Khmer, and Mongolian run on one or two days a week (as of 2026-08).⁶

The 労働条件相談ほっとライン (rōdō jōken sōdan hotto rain, "Labour Standards Advice Hotline") is a free MHLW-commissioned service covering the hours when bureaus and inspection offices are closed.⁶ It runs weekday evenings 17:00 to 22:00 and weekends and holidays 9:00 to 21:00, with a Japanese line plus foreign-language lines that each operate only on specific days (as of 2026-08).⁶

In-person foreign-worker consultation corners sit at listed bureaus and inspection offices, each with its own languages, days, hours, and phone number.⁶ Examples include the Tokyo Labour Bureau Special Consultation and Support Office for Foreigners and the Osaka Labour Bureau Inspection Division; availability varies office by office (as of 2026-08).⁶

Filing in Japanese in practice

Phone lines give advice; formal action generally means an in-person visit where Japanese is the working language.⁶² Interpreter availability follows the scheduled consultation-corner days, so a language available by phone on Friday may have no interpreter at the inspection window that day.⁶

Practitioner sources count 18 inspection offices in Tokyo and 14 in Osaka, found through the prefectural Labor Bureau site by workplace location (as of 2026-03).² The office count comes from a single practitioner source; use the bureau site, not this figure, to find your counter.²

Good to know

File at the office covering your workplace, not your home

Jurisdiction follows the workplace location.¹² A worker who lives in Yokohama but works in Shinjuku files in Shinjuku. Check the prefectural Labor Bureau site for the office covering the job address before visiting.²

A consultation does not start an investigation on its own

Phone and hotline consultations are advice-only channels.² Workers who describe the problem, hear that it looks like a violation, and hang up have not set enforcement in motion. The investigation starts with the formal shinkoku.²

Bring pay slips and time records, not just a narrative

Inspectors test the employer roster, wage ledger, and 36 Agreement against evidence.⁴ A personal hours log plus pay slips gives the inspector something to compare; a bare account of long hours gives little to check.¹²

Retaliation for filing is itself a violation

Disadvantageous treatment for using the consultation or complaint system is prohibited by law.⁷ A demotion, transfer, or dismissal that follows a filing is a fresh violation to report, not a cost of complaining to absorb.⁷²

Anonymous tips inform but rarely compel action

Anonymous contact gets guidance or alerts the office to a possible violation.¹ A named in-person complaint with evidence is what gets an investigation and a correction order.¹ Choose the anonymous route for orientation, the named route for enforcement.¹
