Labour at serviced housing for the elderly — staffing for safety checks and daily-life counselling, and the night-time setup

In short: Labour at serviced housing for the elderly (Sakoju) turns on how you place the daytime staff who provide safety checks (status monitoring) and daily-life counselling, and, where night staff are placed, whether they are on actual night-shift work or on permitted night duty — designed through working hours and wages. A general-type Sakoju has no care-insurance staffing ratio like the 3-to-1 (one per three residents needing care, full-time equivalent) of a specified facility (fee-charging elderly home with care). The registration standard requires staff who provide status monitoring and daily-life counselling to be present in principle in the daytime (around 9 a.m. to 5 p.m.); whether to place staff at night is not mandatory under the registration standard, and unstaffed hours are generally covered by an emergency call device in each dwelling unit (Act on Secured Stable Living of the Elderly, Act No. 26 of 2001, Articles 5 and 7, and its enforcement regulations). Where night staff are placed, whether the work is an actual night shift or night duty with ordinarily almost no need to work changes whether late-night and overtime premiums are required. This article sets out, within a Shakai Hoken Roumushi's work, the difference from a specified facility, who provides safety checks and counselling, the night-shift/night-duty distinction, social insurance, and dividing labour from an external home-care provider.

"How many staff, with what qualifications, should I place when I open a Sakoju?" and "I hear one person is enough at night — can that be night duty?" — these are questions we often hear from operators opening and running a Sakoju. This page organises the staffing for status monitoring and counselling and the night-time setup as a labour design — working hours, premium wages and social insurance — on the premise of a general-type Sakoju. Whether the registration itself succeeds and whether the registration standard is met is the domain of the registering authority (prefecture / designated city / core city) and application practice; this article focuses on the labour thinking.

How does staffing differ between a Sakoju and a fee-charging elderly home with care (specified facility)?

The first thing to grasp is that a general-type Sakoju and a fee-charging elderly home with care (specified facility residents' daily-life care) are governed by different laws for their staffing standards.

	Sakoju (general type)	Fee-charging elderly home with care (specified facility)
Basis	Registration standard under the Act on Secured Stable Living of the Elderly	Designation standard under the Long-Term Care Insurance Act (Ministerial Ordinance No. 37 of 1999)
Staff placed	Staff providing status monitoring and daily-life counselling	Nursing staff, care staff, living consultant, functional training instructor and others
Care staffing ratio	None (care is received from an external provider)	At least 1 per 3 residents needing care (full-time equivalent)
Who provides care	An external care provider the resident contracts with	The facility (a provider holding the specified-facility designation)
Night staff present	Not mandatory under the registration standard (an emergency call device may cover)	A night-shift staffing requirement applies under the designation

A specified facility itself provides care-insurance-covered services, so a full-time-equivalent staffing is a requirement for the designation. A general-type Sakoju, by contrast, is at its core "housing plus watch-over (status monitoring and daily-life counselling)," and care is received separately by the resident under a contract with an external provider such as a home-care service. So what the Sakoju operator places under the registration standard is not care staff but staff who provide status monitoring and counselling. For the night shift and staffing of a specified facility, see how do you design the staffing standard and night shift at a fee-charging elderly home with care. Which type you are changes both the staff you place and the working-hours design.

Who provides safety checks and daily-life counselling? (qualifications, presence)

A Sakoju's registration standard requires that status monitoring (safety checks) and daily-life counselling be provided. These are handled by so-called "care professionals" — specifically, qualified people such as the following (or those who have completed a prescribed training).

Item	Content
Who	Physician, nurse, assistant nurse, certified care worker, certified social worker, care manager, or a person who completed a prescribed training (the range is indicated by the registering authority's operation)
Presence hours	In principle daytime; around 9 a.m. to 5 p.m. is assumed
Place of presence	A building on the housing's site or an adjacent site
Method of status monitoring	At least once a day, by visiting the unit or another appropriate method (visit, phone, monitoring device)
Unstaffed hours such as at night	Covered by an emergency call device installed in each dwelling unit

What matters in labour terms is "how you reliably place this on-site staff in the daytime, under what employment contract and shift." Presence only works when a person is there, so build shifts with a margin so the daytime presence is never left empty by paid leave, absence or training. The presence requirement may, since September 2022, be eased where certain conditions are met, but the specific conditions differ by the registering authority's (local) operation, so this article avoids asserting the details (treated as unverified). Work rules must be prepared and filed at establishments with 10 or more workers at all times (Labor Standards Act, Article 89). See from how many workers must you prepare and file work rules.

What setup is needed at night? How do night shift and night duty differ?

At a general-type Sakoju, placing staff at night is not mandatory under the registration standard, and unstaffed hours are generally covered by an emergency call device. Still, many operators place staff at night for residents' peace of mind, and whether you set that up as "night duty" or "night shift" is where the labour treatment divides.

Aspect	Night shift (actual)	Night duty (where permitted)
Actual work	Ordinary watch-over, emergency response, recording — continuous work	Scheduled rounds, standby for emergencies — intermittent work
Working time	Counts as working time	Exempt from working hours, breaks, days off
Late-night premium (10 p.m.–5 a.m.)	25% or more required	In principle not required
Overtime premium	25% or more for time beyond statutory hours	In principle not required
Permission	Not required (managed as working time)	Permission of the labour standards inspection office director required

To take work out of the working-hours rules as night duty, it must be intermittent work with ordinarily almost no need to work, and obtain the permission of the director of the labour standards inspection office (Labor Standards Act, Article 41, item 3; Enforcement Ordinance, Article 23; Notice Hatsuki No. 17 of 13 September 1947). If responses to emergency calls are only occasional and staff can secure adequate sleep at night, it may qualify as night duty; but if watch-over and assistance arise frequently, it is treated as a night shift, requiring the late-night premium (Article 37, paragraph 3) and, for time beyond statutory hours, the overtime premium (paragraph 1). As with care facilities, the reality — not the label — decides. For night-duty permission standards, see what kind of duty qualifies for night-duty permission in medical and care settings; for the night-shift/night-duty difference at a disability group home, see how do night shifts and night duty differ for labour at a group home. Time when one must respond to an emergency call even during a nap can be hand-waiting time and thus working time.

How do you enrol in social insurance and labour insurance?

If the Sakoju operator employs workers, enrolment in social insurance (health insurance and employees' pension) and labour insurance (workers' accident compensation and employment insurance) comes into play.

• Workers' accident insurance: applies once you employ even one worker, regardless of business type or scale. Part-timers are covered without distinction
• Employment insurance: a worker whose prescribed weekly hours are 20 or more and who is expected to be employed for 31 days or more becomes insured (the scope is set to expand in stages, so confirm the latest effective timing)
• Health insurance and employees' pension: corporate establishments are compulsorily covered; sole proprietorships are compulsorily covered in certain business types employing 5 or more at all times. Part-time and short-hour workers enrol where their prescribed hours/days are three-quarters or more of a regular worker's, and even below three-quarters where requirements such as firm size are met

When hours vary month to month under night shifts or a variable working-hours system, mistakes are easy in the standard monthly remuneration and occasional revision, so keep wage regulations and attendance records in order. For the three-quarters line for short-hour workers' social insurance, see how is short-hour workers' social insurance decided by the three-quarters rule. Calculating premiums and the acquisition/loss procedures are the work of a Shakai Hoken Roumushi.

When using an external home-care provider, how do you divide the labour?

At a general-type Sakoju, care for residents is handled by an external home-care provider. Here the labour divides on the point that "staff the Sakoju operator employs" and "home helpers the home-care business employs" are treated as the labour of different business entities.

What is done	Whose labour
The Sakoju's status-monitoring and counselling staff; the night-time setup	The Sakoju operator (the subject of this article)
Home helpers' working hours, travel time and wages for providing care to residents	The home-care business (designed separately per establishment, even if the same corporation runs it on-site)

The same corporation often runs an attached home-care business; then that business's staffing standard (full-time equivalent) and the helpers' travel-time and standby working-hours management arise separately from the Sakoju itself. For the home-care-specific issue of travel time as working time, see is travel time in home care counted as working time. Even for "people working in the same building," the working-hours and wage design differs by which establishment employs them.

Whom should you separate the work to?

In opening and running a Sakoju, who decides divides by role. Separating the roles and entrusting each to its professional is safer.

What is done	Whose domain
Work rules, wage regulations, the 36 Agreement and a variable system; the night duty/night shift design; premium wages; social and labour insurance	Shakai Hoken Roumushi (四葉社会保険労務士事務所)
The Sakoju registration and change filings; documents such as the designation application for an external care service	Gyoseishoshi (四葉行政書士事務所)
Barrier-free design, use and floor area of the building	Architect
Care-fee billing and tax	Operator and tax accountant
Unpaid-wage claims and disputes, labour tribunal and litigation	Attorney

FAQ

Q. Must a Sakoju place staff at the same ratio (3-to-1) as a fee-charging elderly home with care?
A. No. The care-insurance staffing ratio (at least one per three residents needing care, full-time equivalent) does not apply to a general-type Sakoju. What a Sakoju places is staff providing status monitoring and counselling, present in principle in the daytime (around 9 a.m.–5 p.m.). The 3-to-1 is the designation standard for a specified facility (fee-charging elderly home with care) that itself provides care.

Q. I hear one person is enough at night. Can that person be on "night duty"?
A. It depends on the reality. If it is intermittent work with ordinarily almost no need to work and adequate sleep can be secured at night, it may be night duty with the permission of the labour standards inspection office director (Article 41, item 3). But if watch-over and emergency responses arise frequently, it is treated as a night shift subject to late-night and overtime premiums. The reality, not the label, decides.

Q. Can the status-monitoring and counselling staff be unqualified?
A. The registration standard assumes qualified people such as a physician, nurse, certified care worker, certified social worker or care manager, or a person who completed a prescribed training. Which qualifications or training are accepted is indicated by the registering authority's (local) operation, so confirm before the registration application.

Q. Can the labour for the home helpers of an attached home-care business be entrusted under the same contract?
A. Because the establishment unit differs, they are considered separately. The Sakoju's status-monitoring and counselling staff and the home-care business's helpers are, even within the same corporation, the labour of different establishments, with staffing, travel time and wages designed separately. Work rules and wage regulations are also arranged to each establishment's reality.
