A house, not a ward
Japan's group homes (guruupu houmu) are dementia care built on a deliberately small scale: units of up to nine residents who share something shaped like household life, with staff cooking alongside residents, laundry hung together, and a routine closer to a home's than an institution's.
The model exists because familiarity and routine are themselves dementia care: in a nine-person house, staff know that Mrs. Sato folds towels when anxious, and the day is built from recognizable domestic acts rather than scheduled programs. The scale is fixed by regulation, not preference: a unit (yunitto) holds five to nine residents and no more, and a single home may run one, two, or at most three of these units side by side, which is why even a large-looking building is really a cluster of small households rather than one floor of beds. Staffing is set to match: during the day the rule is one care worker per three residents counted in full-time-equivalent terms, and at night at least one staff member stays awake in each unit, so a two-unit home keeps two people on overnight. The category's formal name, ninchisho taio-gata kyodo seikatsu kaigo, translates roughly as communal-living care for dementia, and the survey count is substantial: 14,341 such homes were operating nationwide as of the 2024 MHLW facility survey, a figure that has crept up by only a few hundred a year as new openings nearly balance closures. For many families comparing options after a dementia diagnosis, the group home is the warmest-feeling answer on the list, which makes its two hard constraints (eligibility and geography) worth understanding before falling for one. The wider dementia landscape is covered in our dementia care in Japan article.
Who qualifies, and the same-town rule
Group homes are community-based services (chiiki mitchaku-gata), which produces the constraint that surprises families most: residency. As a rule, the parent must be a registered resident of the same municipality as the home.
The other gates: a dementia diagnosis, and certification at support level 2 or any care level. The cutoff sits exactly there: support level 1 does not qualify, while support level 2 enters through the preventive version of the service and care levels 1 and above through the standard one. The parent also has to be stable enough to share a household; the model assumes someone who can take part in cooking, cleaning, and daily life with prompting, not someone bedbound. The residency rule has a real consequence for planning: a family hoping to move a parent near them must usually move the parent's resident registration first, then apply, which adds months and paperwork to any cross-town plan. For overseas families whose parent lives in a small municipality, the local supply might be two or three homes total, so the candidate list is short enough to know personally, and the community support center knows them all.
What it costs
Group homes sit in the middle of the facility cost range, with little or no entrance fee at most homes and a bundled monthly structure.
As orientation: monthly all-in costs commonly land around ¥120,000 to ¥200,000, combining rent, meals, utilities, and the covered care co-payment, varying with the home and region. Two cost behaviors to check in the disclosure documents: how charges change as the care level rises, and what the home's policy is on hospitalization absences (whether the room is held and at what cost). The income-based reductions that lower tokuyo bills generally do not apply to group home rent and meals, which is one reason the cheaper-looking tokuyo often wins on price for low-income residents despite the group home's smaller scale. The reason is structural: the burden-limit certification (futan gendogaku nintei) that caps room and meal charges is written for the public nursing-home institutions, and a group home is legally a community-based service rather than one of those institutions, so a pension-only resident who would pay a heavily reduced rate in a tokuyo pays the home's full posted rent here. A few municipalities run their own modest rent subsidies for group homes, but they are local, small, and not guaranteed, so families should confirm with the parent's town office rather than assume the national reductions carry over.
The two questions that decide whether it lasts
Group homes do not hold every resident to the end, and the exits are predictable enough to ask about on the first visit.
Medical: group homes are care settings, not nursing ones; a nurse is not necessarily on staff, so conditions needing daily medical procedures can force a move. Ask specifically which medical needs the home can and cannot hold, and what happened to the last three residents who left. End of life: homes split on mitori (end-of-life care); some see residents through with visiting doctors, others transfer when decline steepens. A home whose answers are concrete on both has thought about it; one that waves at the questions has not. The same exit logic applies as everywhere: a placement that cannot hold the likely trajectory is a two-move plan, and dementia trajectories mostly point one direction.
Waiting, applying, and judging the house
Good group homes carry waiting lists measured in months, sometimes longer, in exactly the places families want them.
Apply early and to several homes at once (allowed and normal), keep the applications warm with updated information, and use the waiting time for day services or small-scale multifunction services that build the parent's tolerance for group settings. Judging the house itself is mercifully concrete at this scale: visit at mealtime, count how many residents are engaged versus parked, watch whether staff talk to residents or about them, and smell the kitchen, because in a real group home someone is cooking. Nine people is small enough that the atmosphere you observe on a Tuesday is the atmosphere your parent will live in.
Frequently asked questions
Who can enter a dementia group home in Japan?
A person with a dementia diagnosis, certified at support level 2 or any care level, who is a registered resident of the same municipality as the home (group homes are community-based services). The community support center knows the local homes and their lists.
How much does a group home cost monthly in Japan?
As orientation, commonly ¥120,000 to ¥200,000 all-in per month (rent, meals, utilities, care co-payment), usually with little or no entrance fee. Tokuyo-style income reductions generally do not apply, so compare against other options at the parent's actual income.
Can a group home care for a resident until the end of life?
It varies by home. Some provide mitori (end-of-life care) with visiting doctors; others transfer residents when medical needs grow, since nurses are not necessarily on staff. Ask each home concretely which conditions it can hold and what happened to recent leavers.
Can we move a parent to a group home near us in another city?
Usually only by first moving the parent's resident registration to your municipality, because of the community-based residency rule. That adds months and paperwork, so families planning a cross-town move should sequence the registration change before applying.
