Practical guidance for documenting time, rest, and pay.
Back to HomeJapan’s labor rules apply to many foreign employees in the same way they apply to Japanese nationals. If you are working under an employment contract in Japan, your employer generally must track your work hours, provide required breaks, and pay wages on time. When something feels “off,” your best leverage is a clear record of what you worked and what you were paid.
Quick takeaways
- Keep your own time log, even if the company uses a clock-in system.
- Save pay slips, bank transfers, messages about shifts, and any schedule changes.
- Ask for clarification in writing when overtime or break rules are unclear.
- If wages are withheld, focus on evidence and a calm, documented request first.
1) Overtime basics: what matters in practice
Overtime disputes often come down to definitions: what counts as “working time,” what your regular schedule is, and whether the employer required or effectively expected the extra work. Time spent preparing for work, closing tasks after your shift, or waiting on-site can matter if it is under the employer’s direction.
Tip: if you are routinely asked to “finish before leaving,” note the request, the task, and the end time each day.
2) Breaks: how to spot violations
Break requirements are tied to how long you work in a day. A break that exists on paper is not enough if you are still expected to answer calls, stay at your desk “just in case,” or can’t freely use the time. If you regularly work through lunch because of staffing shortages, record it as work time.
- Is the break uninterrupted? Being on standby can turn “break” into working time.
- Is it actually taken? If the schedule shows a break but the workload makes it impossible, document the reality.
- Are breaks deducted automatically? Automatic deductions can be a red flag when breaks are not truly taken.
3) Unpaid wages: common patterns
Unpaid wages are not always a total non-payment. They can appear as undercounted hours, missing overtime premium, automatic break deductions, unpaid “training,” or pressure to report fewer hours. Another common issue is delayed final pay after resignation or contract completion.
What to request from your employer
- Itemized pay details (base pay, allowances, overtime, deductions).
- Time records for the relevant period (clock-in/out logs, shift rosters).
- A written explanation of how hours and breaks were calculated.
4) Your documentation kit (bilingual-friendly)
You don’t need perfect Japanese to build a strong record. Consistency beats complexity. Create a folder (cloud + local) and save everything in chronological order.
- Daily time log: start, end, break taken, location, and who approved overtime.
- Schedules and changes: screenshots of apps, chat messages, emails.
- Pay evidence: pay slips, bank statements, tax/insurance notices if relevant.
- Work output timestamps: system logins, sent emails, submission receipts.
Simple log format
YYYY-MM-DD | Start 09:05 | End 20:10 | Break 20m | O/T asked by: (name) | Notes: closing tasks, customer calls
If you can, record in English and add key Japanese terms you see in company messages.
5) Escalation steps if the problem continues
Start with a clear, polite written request that states the dates, the missing hours or amounts, and the evidence you have. If the company does not respond or retaliates, consider getting help from a professional or a public office.
- Internal: email HR or your manager and keep copies.
- Consultation: a labor union, a lawyer, or a support organization that can assist in Japanese.
- Public office: the local Labour Standards Inspection Office (労働基準監督署).

6) Protect yourself while raising the issue
Keep communications factual and avoid signing documents you do not understand. If you are presented with a “settlement” or a resignation-related paper, request time to review it and get it translated. If you feel pressured, write down who said what and when.
