Labor at a drugstore — the registered seller's on-site duty and building shifts around opening hours

In short: A drugstore's labor rests on shifts that never lack the store manager and a qualified person (pharmacist or registered seller) during opening hours. Pre- and post-opening work and late-night hours count as working time, with a late-night premium for 10 p.m. to 5 a.m. Long-hours stores can allocate scheduled hours with a variable working-hours system. The license and the qualified-staff placement rules themselves are pharmaceutical matters, handled separately from labor.

A drugstore without dispensing sells, under pharmaceutical law, as a "store-based drug-selling business," centered on second- and third-class over-the-counter drugs. In preparing to open, attention tends to go to premises, the license, and shelving, but "can you place the store manager full-time?" and "can you run shifts without ever lacking a pharmacist or registered seller during opening hours?" tie directly into working-hour, late-night-premium, and social-insurance design. Pin down the labor foundation first. Labor at a dispensing pharmacy (premised on a managing pharmacist) is in labor when opening a pharmacy — the full-time managing pharmacist and shifts; this article focuses on on-site presence and shifts centered on the registered seller of a store-based drug-selling business.

How do you build shifts around opening hours given the on-site duty of qualified staff?

A store-based drug-selling business must place a "store manager" who manages the store on site, and the manager must be a pharmacist or a registered seller (Pharmaceutical and Medical Device Act, Article 28(1)(2)). The manager may not, as a rule, engage in pharmaceutical work at any place other than that store; concurrent work requires the permission of the prefectural governor where the store is located (Article 28(4)). Further, during hours when second- and third-class drugs are sold, a pharmacist or registered seller must be in the store. So "can you place a dedicated, full-time manager?" and "can you avoid lacking a qualified person during selling hours?" are the starting points of shift design.

Issue	What the shift decides
The store manager's hours	Enough dedicated, full-time hours to manage on site (Article 28(4))
Qualified staffing during selling hours	Rotation that never lacks a pharmacist or registered seller (during second-/third-class selling hours)
Social and employment insurance coverage	When coverage obligations arise, as a workplace and for each employee

Note that the pharmaceutical "dedicated, on-site management" and the labor/social-insurance sense of "full-time" are different yardsticks. On the labor side, stating scheduled hours and workdays clearly in the employment contract and work rules, backed by attendance records, is safe for both pharmaceutical and labor purposes. How many hours meet the manager requirement is a matter for the pharmaceutical licensing authority (prefecture / public health center), so confirm it within the license preparation.

How are premium wages and the variable working-hours system handled for pre-/post-opening work and late-night hours?

A drugstore has pre-opening stocking and ordering and post-closing register and cleaning work, and many stores open late at night. Working-hour management follows the Labor Standards Act's principles regardless of industry.

Item	Content
Statutory working hours	In principle 8 hours a day and 40 hours a week (Labor Standards Act, Article 32)
Breaks	At least 45 minutes for over 6 hours, at least 1 hour for over 8 hours (Article 34)
Holidays	At least one day a week, or four days in four weeks (Article 35)
Overtime and holiday work	Cannot be ordered without an Article 36 agreement (Article 36)
Premium wages	Overtime 25%+, late-night (10 p.m.–5 a.m.) 25%+, holiday 35%+ (Article 37)

Pre- and post-opening work is working time if it is under the employer's direction. If "assemble 30 minutes before opening" is effectively mandatory, those 30 minutes count as working time and are paid. For late-night operation, a late-night premium of 25% or more applies separately to the 10 p.m.–5 a.m. band (minimum wage is an hourly amount, so the late-night premium is added on top). For stores with long hours, or different weekday and weekend hours, a monthly-unit variable working-hours system (Article 32-2) or a yearly-unit one (Article 32-4) makes it easier to allocate scheduled hours to weekly or seasonal peaks and troughs. See how to choose between the variable working-hours system and flextime.

How do the registered seller's training and manager requirements affect hiring and labor?

Not every registered seller can immediately become a store manager. To be the manager of a store selling second- and third-class drugs, the rule is, in principle, engagement for 2 or more years within the past 5 years and a total of 1,920 hours or more (or 1 or more years and 1,920 hours or more with both continued and additional training completed, etc.) (Pharmaceutical and Medical Device Act Enforcement Regulations, Article 140 and others). Until meeting these hours, a registered seller is treated in practice as "in training," with limits on selling and providing information alone, working under the management and guidance of a pharmacist or a registered seller who meets the manager requirement (MHLW notices such as "Handling of the registered-seller system"; referenced 6 November 2026).

This directly affects hiring and labor. How many registered sellers you can secure to entrust as managers, how to work into the shifts that you cannot place an in-training registered seller in solo bands, and how to design scheduled hours to meet the required hours — these are the staffing plan and work-rules design themselves. Scheduled hours and workdays also bear on the social-insurance entry point below, so decide them clearly at hiring. Which work counts toward the manager requirement's "engagement hours" and whether training is required are matters for the pharmaceutical licensing authority, so confirm them within the license preparation.

How do you run the labor, the license, and the premises — who handles which, separately?

Opening a drugstore splits by qualification, and each is a separate contract.

Task	Main responsibility
Shift design and work rules, late-night-premium and variable-hours design, social/labor-insurance tests and procedures, payroll	Shakai Hoken Roumushi (our office)
Store-based drug-selling business license, arranging registered-seller/pharmacist placement rules	Gyoseishoshi (or the opener)
Zoning and floor-area and other premises selection, brokerage and disclosure	Real estate transaction agent
Confirmation of change of use under the Building Standards Act	Architect / designated administrative agency
Opening taxes and returns	Tax accountant

We can introduce you to 四葉行政書士事務所 for the license and placement rules and to 四葉不動産 for the premises, but 四葉行政書士事務所 and 四葉不動産 are independent entities separate from our office, and the Shakai Hoken Roumushi work, Gyoseishoshi work, and real estate work are contracted separately (we do not take them on together). Our office receives no referral fee. The detailed arrangement of the license and placement rules is on the Gyoseishoshi side in the drugstore (store-based drug-selling business) structure, equipment, and registered seller, and the premises view in the real estate column.

四葉社会保険労務士事務所 can advise on shift design premised on a full-time store manager, late-night-premium and variable-hours design, the social-insurance test for pharmacists and registered sellers, and preparing work rules. Fees are in the fee schedule, and payroll rates in how much it costs to have a Shakai Hoken Roumushi handle payroll.

From what point do social and employment insurance obligations arise?

First, confirm whether the store is a workplace covered by social insurance (health insurance and employees' pension). Selling drugs — goods — falls within the applicable industry (the business of selling goods) under the Health Insurance Act and Employees' Pension Insurance Act.

Business form	Health insurance / employees' pension
Corporation (KK, etc.)	Compulsory even with the owner alone
Sole-proprietor store	Compulsory with 5 or more regular staff (selling goods is an applicable industry)

Once covered, whether part-time registered sellers and pharmacists join is judged against regular employees: they join if both weekly scheduled hours and monthly scheduled workdays are three-quarters or more of a regular employee's. Even under three-quarters, at a specified covered workplace they become subject if 20+ hours a week, a monthly wage of 88,000 yen or more, expected employment over 2 months, and not a student. The size requirement expands in stages — 51+ insured persons, and 36+ from October 2027 — and the 88,000-yen wage requirement is scheduled to be abolished in October 2026. Counting is in what happens to social insurance when you hire for short hours, the timing in social-insurance coverage expansion to 36+ from October 2027, and explaining it to those within a dependent's range in what employers should do about abolishing the 1.06-million-yen wall. For employment insurance, someone with 20+ scheduled weekly hours (10+ from October 2028) and expected employment of 31 days or more is insured; work rules must be drawn up and filed from 10 or more regular staff (Article 89; from how many people are work rules mandatory).

Frequently asked questions

Q. Can a registered seller become a store manager right after being hired?
A. No, in principle not immediately. To be the manager of a store selling second- and third-class drugs, the rule is, in principle, engagement for 2 or more years within the past 5 years and a total of 1,920 hours or more (or 1 or more years and 1,920 hours or more with both continued and additional training completed, etc.) (Enforcement Regulations, Article 140 and others). Until then they are "in training," with limits on selling alone, working under management and guidance. How many managers you can secure directly shapes the hiring plan, so sort it out early. Whether a specific case meets the requirement is a matter for the pharmaceutical licensing authority.

Q. Do pre-opening stocking and post-closing register work count as working time?
A. If the work is under the employer's direction, it is working time. Pre-opening assembly and preparation that is effectively mandatory, and post-closing settling work, count as working time and are paid. Work beyond 8 hours a day or 40 hours a week presupposes a filed Article 36 agreement, and premium wages apply to the excess. Aligning time-card rules with reality and making start/end times clear in work rules and attendance records prevents unpaid-overtime trouble.

Q. How do you calculate wages at a store open late at night?
A. For work in the 10 p.m.–5 a.m. band you add a late-night premium of 25% or more to the usual wage (Article 37(4)). Because minimum wage is set as an hourly amount, the late-night premium is added on top of that hourly amount. If that late-night work also exceeds statutory hours, the overtime premium (25%+) and late-night premium (25%+) stack. At a store with long hours, a monthly-unit variable working-hours system makes it easier to allocate scheduled hours to peaks and troughs.

Q. Up to how many hours before a registered seller working within a dependent's range joins social insurance?
A. Compared with a regular employee, if both weekly scheduled hours and monthly scheduled workdays are under three-quarters, they in principle do not join. But if the workplace is a specified covered workplace, they become subject with conditions such as 20+ hours a week and a monthly wage of 88,000 yen or more. The size requirement is expanding in stages and the 88,000-yen wage requirement is scheduled to be abolished in October 2026, so judge by the latest requirements. Deciding scheduled hours and workdays clearly at hiring matters.
