Everything in Japan's system hangs off one municipal decision: the care-need certification. The Long-Term Care Insurance Act sets 30 days as the principle. MHLW's fiscal 2023 figures for 1,559 insurers put the median insurer at 39.3 days. The median of insurers' shares decided within 30 days was 21.4%; this is not the percentage of all applications nationwide.
So the first useful question is not which service to pick. It is what to do in the six weeks before the result arrives. Three things are always worth doing.
- Write down what you observed and the date it happened.
- Tell the parent's regular doctor about daily-life difficulties before the written opinion is requested.
- Arrange for a family member to be present at the home assessment.
If a municipal, hospital, or care-plan term is unfamiliar, keep the Japanese elder care glossary open while reading. It defines 52 terms with romaji for each one.
If you are still deciding whether the situation is serious enough to act, the care needs orientation check gives a six-question starting point before you contact the municipality.

How the system works
Long-term care insurance is compulsory from age 40. Registered residents pay premiums into the pool, and the same fund later covers a parent's home help and facility care. The long-term care insurance guide covers enrolment in full.
A municipal review board sets the care level, not a single doctor. It weighs a home assessment against the parent's regular doctor's written opinion, called the shujii ikensho. The result places the parent at one of seven levels, detailed in the care levels guide.
The assessment behind that level is a standard 74-item survey of physical and cognitive condition, plus the assessor's written notes. The review board weighs that score against the shujii ikensho and can move the level up or down.
Once certified, a care manager writes the actual care plan at no charge to the family. Planning is reimbursed to the care manager's office in full by insurance, so the family's only cost is the 10 to 30 percent co-payment on services used. The care managers guide explains how families choose and change one.
Monthly care costs
Each care level sets a monthly ceiling on covered home services, paid in units worth about ¥10 each. The ceiling runs from 5,032 units at support level 1 to 36,217 units at care level 5. Above the ceiling, extra hours are billed in full.
Monthly benefit ceiling by care level, unchanged since October 2019| Care level | Monthly ceiling (units) | Approximate value |
|---|
| Support 1 | 5,032 | about ¥50,000 |
|---|
| Support 2 | 10,531 | about ¥105,000 |
|---|
| Care 1 | 16,765 | about ¥167,000 |
|---|
| Care 2 | 19,705 | about ¥197,000 |
|---|
| Care 3 | 27,048 | about ¥270,000 |
|---|
| Care 4 | 30,938 | about ¥309,000 |
|---|
| Care 5 | 36,217 | about ¥362,000 |

The ceiling caps what insurance covers, not what a household pays. A separate high-cost care benefit caps the monthly co-payment itself, commonly around ¥44,400 for an ordinary-income household, rising to ¥93,000 for the ¥3.8 to ¥6.9 million taxable band and ¥140,100 above it. Anything paid over the cap is refunded on application, so the refund is claimed rather than automatic. It does not touch rent or meals.
The value column assumes a unit worth about ¥10. The real unit price is set by area and by service type, so a Tokyo ward and a rural town do not convert the same ceiling to the same amount. Treat the units as the fixed figure and the yen as an order of magnitude.
Home care commonly runs ¥10,000 to ¥30,000 a month in co-payments on top of ordinary living costs. A special nursing home runs about ¥80,000 to ¥150,000 all-in with no entrance fee, and a private paid home runs ¥150,000 to ¥350,000 or more plus an entrance fee. The costs guide breaks down each facility type and the reductions families miss.
Across a full period of care, the 2024 national survey average works out to about ¥90,000 a month for four years and seven months, plus ¥470,000 in one-time costs. Whether that fits inside the monthly ceiling depends on night-time needs and how far the nearest provider is, which the home care versus facility care guide walks through.
Who to call first
The community support center is the free municipal window for the first call, with about 5,487 of them nationwide as of April 2025. Staff there can take the first consultation and file the certification application for the family. The community support centers guide lists what to bring.
The municipality's long-term care insurance section is the office that actually processes the application and issues the certification. It is a separate desk from the National Health Insurance section, though both work from the same registered address.
Ask for the long-term care insurance section by name. Bring the parent's insurance card, their registered address and a written account of daily difficulties. Assessors plan around specifics, not general concern.
After certification, a care manager takes over and visits the parent's home at least once a month under the national operating standards for home-care support offices. That is roughly twelve recorded visits a year.
Foreign residents in Japan
Enrolment in health insurance and long-term care insurance is triggered by registering an address, not by the type of residence status held. The registration is a move-in notification, filed at the municipal office within 14 days of settling. That single filing also activates the National Pension and My Number.
A foreign spouse of a Japanese national typically enters on a Spouse or Child of Japanese National status, applied for with a Certificate of Eligibility that the Japanese partner files before the move. The certificate commonly takes one to three months, so it belongs at the top of a moving timeline. The moving to Japan guide sets out the residence-status gate before insurance and care questions.
Once registered, foreign residents are enrolled on essentially the same terms as Japanese nationals. What varies is age category and how recently the residence card was issued. The retiring in Japan guide maps every public system a senior resident enters, in order.
Families living abroad
Municipal offices and care providers keep Japanese business hours, which fall in the middle of the night for London or New York. The home assessment also needs someone in the room who can describe an ordinary bad day rather than a good one. The caring for parents from overseas guide sets out who does what from where.
Filing the application, choosing the care manager's office and approving the care plan can all be done from abroad. Most of it works on paper or by phone through the community support center. What still needs a person physically in Japan is the home assessment and the first provider introductions.
A family member who leaves Japan for good is dropped from the resident register and loses both National Health Insurance and long-term care enrolment at the same time. Coming back resets the clock, and a move-in notification within 14 days re-opens both at two separate municipal desks. The returning to Japan guide walks through the re-registration in order.
Documents to have ready
Municipalities move faster when a family arrives with paperwork rather than only a request for help. The core set rarely changes across cases.
- The care-insurance certificate or its number, if the parent already has one
- The certificate of residence and, for foreign residents, the residence card
- A dated written account of daily difficulties, for the assessor and the regular doctor
- The certification application form, available at the municipal long-term care insurance section
