Care-Level Certification (Yoshien / Yokaigo)

Care-Level Certification Japan is the municipal procedure that decides how much long-term care a person needs and unlocks covered services under Long-Term Care Insurance.¹ For families, it is the gateway step: without a certified level, there is no covered care plan, only private payment. This article walks through where to apply, what the home visit and doctor letter involve, how long the decision takes, and what each of the seven levels buys.

Procedures, fees, and requirements can change. Confirm current details at the Ministry of Health, Labour and Welfare (厚生労働省, MHLW) certification guidance and your own municipality's Long-Term Care Insurance desk.

Overview

The 要介護認定 (yokaigo nintei, "certification of needed long-term care") and its lighter sibling the 要支援認定 (yoshien nintei, "certification of needed support") are municipal judgments of how much caregiving effort a person needs.¹² The judgment measures care time needed, not disease severity alone. A person with mild physical impairment plus dementia-related wandering can assess higher than a bedbound person without behavioral symptoms.³⁴

Certification is required before any covered service starts. Home-visit care, day services, short stays, equipment rental, and facility placement under insurance all wait on the mailed result notice.²

The terms below recur throughout this article:

Japanese term	Romaji	English gloss
要介護認定	yokaigo nintei	Certification of needed long-term care
要支援認定	yoshien nintei	Certification of needed support
介護保険	kaigo hoken	Long-Term Care Insurance
特定疾病	tokutei shippei	Specified age-related diseases gating age 40 to 64 eligibility

Who certification covers

People 65 and older (the 第一号被保険者, daiichigo hihokensha, "Category 1 insured persons") qualify on need alone, with no specific diagnosis required.¹⁵ People 40 to 64 (the 第二号被保険者, dainigo hihokensha, "Category 2 insured persons") qualify only when the need for care is caused by a specified age-related disease, a list of 16 conditions that includes ALS, Parkinson-related disorders, rheumatoid arthritis, and cerebrovascular disease.¹⁶

Need must be expected to continue for about 6 months in principle.¹ Terminal cases such as end-stage cancer can move on a faster track even below that horizon.⁶ Foreign residents with legal municipal residence are fully eligible under the same rules. There is no nationality gate.¹⁷

Where to Apply

Apply at the municipality's Long-Term Care Insurance desk (the exact division name varies by city).⁷²⁶ Many cities also accept filing through the 地域包括支援センター (chiiki hokatsu shien senta, "community comprehensive support center"), the free neighborhood consultation window that advises whether to apply and can file as your proxy.⁷²

Filing routes are counter submission or mail, and some municipalities offer downloadable forms on their websites.²⁶ Reception hours, counter names, and whether mail filing is accepted are set ward by ward, so confirm with the specific municipality before visiting. Filing itself is free (as of 2026-08; confirm current figures with your municipality).⁶

What to bring and who can file for you

The applicant, a family member, the community support center, or the care manager can file.² A family proxy generally needs a power of attorney on the municipality's designated form plus identification.⁶

Standard items requested at the counter are the Long-Term Care Insurance insured-person certificate, the application form, the health insurance certificate, information on the primary doctor (clinic card, or department and doctor name at a general hospital), and ID.⁷²⁶ Adult-guardian filings add the registration certificate.⁷ Category 2 applicants (40 to 64) need a medical certificate tying the condition to a specified disease.⁶ Preparing the doctor opinion letter itself can carry a separate fee in some cases (as of 2026-08).⁶

The Certification Process

Certification runs in a fixed sequence: application, home-visit survey, doctor opinion letter in parallel, computer-aided primary judgment, expert-board secondary judgment, and a mailed result notice.³¹²⁶ The municipality must interview the applicant face to face and survey physical and mental condition, living environment, and current medical care, and it must separately seek the primary doctor's opinion; both duties sit in the Long-Term Care Insurance Act.¹

The flow looks like this (figures current as of 2026-08; confirm current figures with your municipality for timing):

The home-visit assessment

A trained municipal or commissioned assessor visits the home (or the facility) within days to about a week of application and interviews the person plus family about daily function and living conditions.²⁶ The survey uses the national standard 74-item questionnaire: 62 items on physical and mental function and daily living plus 12 on special medical procedures such as dialysis and pressure-sore care.⁵⁸

The visit takes about an hour, so allow 1 to 2 hours including family interview time (as of 2026-08).⁶² Survey topics include eating, bathing, toileting, dementia symptoms, and communication ability.²

Hand the assessor dated examples of ordinary days

General statements like "Mother is frail" score poorly against a standardized survey. A one-page memo with dated, concrete examples (falls last Tuesday, missed medication twice this month, nights needing supervision) gives the assessor recordable facts and gives the review board something to weigh.⁸

The doctor opinion letter

The municipality asks the family doctor (or hospital doctor) to prepare the 主治医意見書 (shujii ikensho, "primary-doctor opinion letter"), a medical evaluation of the condition, physical function, and dementia status.²⁶ Preparation typically takes several days to a week.²⁶

This track runs in parallel with the survey, and the board cannot finalize until both land, so a slow letter stalls the whole file.²⁶ Confirm the municipality sent the request promptly, brief the doctor on falls and medication problems before it is written, and nudge the clinic early.⁸

A doctor who has not seen the daily problems cannot document them

The board weighs the opinion letter when it overrides the computer result. If the physician only knows the stable clinic presentation and not the falls, the wandering, or the missed doses, the letter understates the case.⁸

Board review and result notice

The primary judgment is computer-aided. Survey answers are matched against national 1-minute time-study data (about 3,500 facility residents observed over 48 hours) through a tree model that estimates standard care minutes across five domains: direct daily-life assistance, indirect assistance, dementia-behavior-related care, function-training-related care, and medical-related care, plus a dementia supplement.³⁴

The municipal Certification Board (介護認定審査会, kaigo nintei shinsakai, "Long-Term Care Certification Board"), a panel of health, medical, and welfare experts hearing each case in a standard group of five, takes the computer result as the draft and reaches the final judgment weighing the surveyor's free-text notes and the doctor letter.³¹⁴ It can move the level up or down from the machine figure.³⁸

Results arrive by mail within 30 days of application in principle, though families commonly experience 30 to 60 days when volume runs high or the doctor letter runs long (as of 2026-08).⁷²⁶ Level thresholds on standard care minutes are fixed nationally: Support 1 is 25 to under 32 minutes; Support 2 and Care 1 share the 32 to under 50 minute band (split by stability and cognition criteria); Care 2 is 50 to under 70; Care 3 is 70 to under 90; Care 4 is 90 to under 110; and Care 5 is 110 or more.³¹⁴

The Seven Care Levels and Monthly Benefit Caps

Results are one of seven levels, from 要支援1 (yoshien 1) lightest through 要介護5 (yokaigo 5) most intensive, or non-certification (非該当, higaito, "not applicable"), meaning assessed as independent with no insurance services.¹²⁸ Each level carries a monthly benefit ceiling (区分支給限度基準額, kubun shikyu gendo kijungaku, "monthly benefit ceiling") for covered home-and-community services, counted in service units.⁸⁹¹⁰

Unit caps are the authoritative figures and convert to yen at the regional unit price, roughly 10 yen per unit in most regions and up to about 11.40 yen in central Tokyo (as of 2026-06; confirm current figures with the Ministry of Health, Labour and Welfare).⁸⁹¹⁰ Amounts above the ceiling are fully private.¹⁰ The table below uses the 10-yen reference conversion; the unit column is what the care manager plans against (as of 2026-06).⁹

Level	Monthly cap (units)	Yen reference (1 unit = 10 yen)	As of	Notes
Support 1 (要支援1)	5,032	about 50,320	2026-069	Prevention-oriented services
Support 2 (要支援2)	10,531	about 105,310	2026-069	Prevention-oriented services
Care 1 (要介護1)	16,765	about 167,650	2026-069	Partial daily assistance
Care 2 (要介護2)	19,705	about 197,050	2026-069	Growing bathing, toileting, mobility help
Care 3 (要介護3)	27,048	about 270,480	2026-069	Extensive daily care; usual tokuyo gate
Care 4 (要介護4)	30,938	about 309,380	2026-069	Near-total care
Care 5 (要介護5)	36,217	about 362,170	2026-069	Total care

Unit figures have been unchanged since the October 2019 revision linked to the consumption-tax rise; the 2021, 2024, and 2026 fee revisions left them in place (as of 2026-06).⁹

Within the ceiling the family pays only the 10 to 30 percent copay on services actually used, tiered by income; the ceiling is a covered-services budget, not a cash payout (as of 2026-06).⁸¹⁰ Facility room and meals sit outside these ceilings, and home-modification work, equipment purchase, and short-stay nights run on separate allowances.⁸¹⁰ New admission to special nursing homes (tokuyo) generally requires Care Level 3 or above.⁸

Over-ceiling spending is fully private without warning at the register

If the month's planned units exceed the ceiling, the excess is billed at 100 percent with no insurance contribution. Mid-month additions like an unplanned short stay are the classic trigger, so ask the care manager to confirm remaining units before adding services.¹⁰

How to read the level table

Support 1 to 2 covers largely independent people needing prevention-oriented help with housework, shopping, or some mobility support.⁸ Care 1 is partial daily assistance, the middle levels add bathing, toileting, and mobility help, and Levels 4 to 5 are near-total or total care, often bedbound or with severe cognitive decline.⁸ These sketches orient only; the assessment keys off functional detail, not labels.⁸

Support 2 and Care 1 share the 32 to under 50 minute band, and the split turns on stability and cognition: unstable acute-phase cases or cases where cognitive impairment blocks understanding of prevention services sort to Care 1.³⁴

The level also works as a switch for covered equipment rental. Wheelchairs, special care beds, pressure-sore prevention mats, and floor-to-bed lifts are in principle excluded at Support 1 to 2 and Care 1 and routinely available from Care 2 upward, with documented-need exceptions the municipality must confirm (as of 2026-06).⁸

Validity, Renewal, and Condition-Change Reassessment

Certification carries a finite validity period set case by case within ordinance bounds.¹ New certification runs 6 months in principle, with the municipality free to set 3 to 12 months.¹ Renewal where the level changed runs 12 months in principle (3 to 36 months at municipal discretion); renewal where the level is unchanged runs 12 months in principle (3 to 48 months at municipal discretion, with extension to 48 months possible since April 2021).¹⁸

Renewal applications can be filed from 60 days before expiry, and the care manager assists with the paperwork.⁷² In practice families experience first certifications around 6 months and renewals commonly around 12 months, while a stable unchanged case can run multiple years without review under the extended bound (as of 2026-06; confirm current figures with your municipality).¹⁸

Renewal timing and the reassessment trigger

When the condition changes materially mid-period (a hospital discharge, a new fracture, faster cognitive decline, or a genuine recovery), anyone can file a classification-change request (区分変更, kubun henko, "classification-change request") that triggers a fresh survey and a new certification rather than waiting for renewal.⁸ This request is the lever that keeps the plan matched to reality between renewals, in either direction.⁸

If a result misses reality in either direction, the municipality explains the review and reassessment routes.⁸ Reapplication is allowed when circumstances change even after a non-certification outcome, so a "not applicable" letter after a fall or illness is a pause, not a final answer.²⁸

Good to know

Prepare for the home visit around an ordinary day

Older applicants often present their best selves to an official visitor, rising unaided from a chair they normally cannot leave alone, and the survey scores what it observes.⁸ Counter this with the dated-examples memo and a family member present who can calmly supply the everyday reality.⁸ Brief the family doctor the same way before the opinion letter is written, since the board weighs the letter when it overrides the computer result.⁸

File early because the clock starts at application

Full-coverage services wait on the mailed result notice, which runs 30 days in principle and up to about 60 in practice (as of 2026-08; confirm current figures with your municipality), so file as soon as the need is clear rather than after a crisis peaks.⁷²⁶ Services used under a provisional care plan before the result arrives carry a real risk: if the certified level comes in lighter than assumed, any over-ceiling portion used provisionally is billed fully private.¹⁰ Confirm the burden risk with the care manager before starting early.¹⁰

The doctor letter can stall the file

The survey and the doctor letter run in parallel tracks and the board cannot finalize until both land.²⁶ A letter that takes more than a week pushes the whole file, and clinics deprioritize paperwork they do not know is urgent.²⁶ Confirm the municipality sent the request, tell the clinic the certification is pending, and follow up within the week.²

Benefit caps are ceilings in service units, not cash payouts

No cash is ever paid out; the ceiling only bounds how much covered service the care manager can plan inside insurance.⁸¹⁰ The family pays the 10 to 30 percent copay on what is used plus 100 percent of any over-ceiling portion.⁸¹⁰ Yen approximations also move with the regional unit price (about 10 yen per unit in most regions, up to about 11.40 yen in Tokyo's top-grade zone), so two families with the same level in different wards see different yen ceilings for identical unit caps (as of 2026-06).⁹¹⁰ Confirm the local unit price when budgeting.⁹

Ward offices differ on counters, hours, and validity length

Counter names, reception hours, mail versus counter acceptance, downloadable forms, and validity length within the ordinance range are municipal choices.⁷² Shizuoka City routes applications through ward Senior Citizen Nursing Care Divisions plus support centers and care-manager and facility proxies, while other cities name a Long-Term Care Insurance Division; neither pattern is national.⁷² Confirm the counter, the hours, and the renewal window with the specific municipality before acting.⁷
