The Japanese Labour Rules Every Boutique Schedule Has to Respect
Guides · 2026-11-13
A monthly rota for a boutique in Japan is a legal document as much as an operational one. The Labour Standards Act (労働基準法) sets limits a schedule must stay inside, and most of them are easy to break by accident when ten advisors, a sale period and three holiday requests meet in one spreadsheet.
This is a manager's checklist of the rules that bear directly on a shift table, and how each one can be written down as a rule the schedule checks for you. It is a summary, not legal advice: your work rules (就業規則) and labour-management agreements decide the details, so confirm them with your HR team or a labour and social security attorney (社会保険労務士).
1. Working hours: 8 a day, 40 a week
Article 32 sets the statutory limit at 8 hours a day and 40 hours a week. Small retail establishments that regularly employ fewer than ten people may use a 44-hour week under a special provision.
Retail rarely fits a flat week, so many boutiques use the monthly variable working hours system (1か月単位の変形労働時間制): hours may exceed 8 on a busy day as long as the average over the period stays within the weekly limit. The condition that matters for scheduling is that each day's hours are fixed before the period starts. A rota published late, or reshuffled freely during the month, undermines the system it relies on.
2. Breaks
Article 34 requires a break of at least 45 minutes when working time exceeds 6 hours, and at least 60 minutes when it exceeds 8. The break has to fall during the shift, not at its end. In a boutique this is a coverage question: with two advisors on the floor, the lunch break is the hour you are most likely to be short.
3. Days off: one a week, or four in four weeks
Article 35 requires at least one day off a week, or four days in any four-week period. These are statutory holidays (法定休日), and they are not the same as the other days off in a contract (所定休日). The difference shows up on the payslip: work on a statutory holiday carries a higher premium than work on an ordinary day off.
A schedule therefore needs to know which rest days count as statutory. Boutique DX lets you set monthly targets for statutory holidays, and attendance exports classify holidays against them.
4. Overtime: the 36 Agreement and its caps
Overtime and holiday work are only lawful under an agreement between the employer and the employees' representative, filed with the labour standards office: the 36 Agreement (36協定), after Article 36. Since the 2019 work-style reform (2020 for small and medium-sized companies), the caps are written into the law itself:
- 45 hours a month and 360 hours a year in principle.
- With a special clause for temporary peaks: at most 720 hours a year, less than 100 hours in any month and an average of 80 hours or fewer over any two to six months (both counting holiday work), and more than 45 hours in no more than six months of the year.
These are totals per person, which is why they are hard to see in a grid of shift codes. The useful view is a running number beside each name. The shift table in Boutique DX shows hours and net overtime next to every advisor, so the person who is about to cross a line is visible while the month is still being planned.
5. Premium pay
Article 37 sets the minimum premiums:
| Work | Minimum premium |
|---|---|
| Overtime beyond statutory hours | 25% |
| Overtime beyond 60 hours in a month | 50% |
| Work on a statutory holiday | 35% |
| Late-night work, 22:00 to 5:00 | 25% |
Premiums stack: overtime that runs past 22:00 earns both. For boutiques in stations and malls that close late, late-night minutes are a regular payroll item, so attendance has to record night hours and overtime the way payroll counts them.
6. Annual paid leave: five days must be taken
Since April 2019, an employer must make sure that every employee granted ten or more days of annual paid leave actually takes five of them within the year (Article 39). The obligation sits with the employer, not the employee. A team that never asks for leave is a compliance problem, not a sign of commitment.
For the schedule this means leave has to be planned in, not fitted around. It also means that closing the request window for a busy period should be a visible, stated rule. Boutique DX handles this with day-off blackout dates: staff see in advance which dates are closed, instead of having a request quietly refused.
7. Rest between shifts
The work interval system (勤務間インターバル制度) asks for a minimum rest period between the end of one working day and the start of the next. Japanese law has made it a duty to make efforts since April 2019, without fixing a number; the figure most often used as a benchmark is 11 hours, the daily rest required in the European Union.
The pattern it rules out is familiar in retail: closing the boutique at 22:00 and opening it at 8:00 the next morning, a gap of ten hours. In Boutique DX the minimum rest is set per contract, and rest-between-shifts templates turn it into a rule the scheduler will not break.
From checklist to rules
Each item above is a number, a period and a group of people: at most this many hours, within this window, for these contracts. That is the form a scheduling rule takes, which is why compliance is better checked while the schedule is being built than discovered on the payslip a month later.
Three questions are worth asking of any tool, including ours:
- Can a manager read each rule, or only the person who configured it?
- When a rule cannot be met, does the tool say which rule, and where?
- Do the hours that were scheduled match the hours payroll receives?
If you would like to see your own work rules written as schedule rules, we can do that with you in a demo. Get in touch.
