Understanding dementia and why it matters in Japan

Dementia is not one single disease. It is a group of conditions where brain cells are damaged, causing problems with memory, thinking, language, mood, and daily activities. Alzheimer’s disease is the most common cause, but there are many others.

In Japan, dementia is a national priority because the population is aging quickly:

• In 2012, about 4.6 million people aged 65+ were estimated to be living with dementia.
• The number is expected to reach around 7 million by 2025, roughly one in five older adults.

More recent projections suggest that when you include people with mild cognitive impairment (MCI), the combined number of dementia and MCI cases could exceed 10 million by 2025.

For expats, this affects:

• Elderly parents who already live in Japan
• Japanese in-laws who are aging
• Retirees who plan to stay long term
• People supporting a parent with dementia from abroad

If you are planning retirement, it’s helpful to read this alongside Healthcare for Retiree Expats: Elder Care and Long-Term Insurance in Japan and In-Home Nursing Care Services in Japan: Options for Injured or Elderly Expats.

Dementia policy in Japan: building a dementia-friendly society

Japan has built a detailed policy framework around dementia over the past decade.

National framework and Basic Act on Dementia

In 2019, the government adopted the National Framework for Promotion of Dementia Policies, which runs until 2025. Its philosophy is that “dementia is a condition that can occur to anyone” and policy should focus on coexistence and prevention – helping people live in their communities while also delaying onset where possible.

In June 2023, the Diet passed the country’s first Basic Act for Dementia, often called the “Basic Law on Dementia.” This law aims to create dementia-friendly communities across Japan and strengthen support for people with dementia and their families.

Key ideas in these policies include:

• Early diagnosis and continuous support, not only late-stage care
• Inclusive communities where people with dementia can stay active
• Support for caregivers, including education and respite services
• Better coordination between medical care, nursing care, and social services

These national plans sit alongside Japan’s broader long-term care insurance (Kaigo Hoken) system, which is the main way dementia care is funded.

How dementia is diagnosed and treated in Japan

Typical pathway to diagnosis

If you suspect dementia, the first step is usually:

1. Visit a family doctor or internal medicine clinic
   • They listen to concerns and do basic checks.
   • They may run simple memory tests and blood work.
2. Referral to a memory clinic or specialist
   • Japan has been building a network of dementia medical centers and memory clinics, including the Center for Comprehensive Care and Research on Memory Disorders at the National Center for Geriatrics and Gerontology.
   • These centers perform more detailed cognitive tests and brain imaging (CT/MRI).
3. Assessment of daily function and care needs
   • Doctors and care managers look at how the person manages money, cooking, medications, and social life.
   • This information later supports the long-term care insurance application.

Early diagnosis is a major goal of recent Japanese dementia policies, not just to prescribe medicine, but to link families to community support and planning.

If you need English support, guides like Top 5 English-Speaking Hospitals in Tokyo (Foreigner-Friendly) and Finding English-Speaking Doctors in Japan can help you choose where to start.

Medical treatment and non-drug support

There is no cure for dementia yet, but doctors in Japan may:

• Prescribe medications to slow symptoms in some forms of dementia
• Treat depression, sleep problems, or agitation
• Manage other health issues (diabetes, hypertension, stroke risk) that can worsen cognitive decline.

Equally important are non-drug supports:

• Occupational therapy and rehabilitation
• Cognitive stimulation and day programs
• Exercise and social activities to maintain function
• Caregiver education and counseling

Articles such as Onsen and Sento 101: Japanese Bathhouse Culture for Health and Relaxation and Staying Active as a Senior in Japan: Community Centers, Gyms, and Parks can also inspire gentle, dementia-friendly activities.

Long-Term Care Insurance and dementia support

How Kaigo Hoken works

Japan’s Long-Term Care Insurance (LTCI / Kaigo Hoken) is a mandatory public system for residents aged 40 and over. Everyone pays premiums; from age 65, people can apply for care services if they need support with daily life due to aging or disability, including dementia.

Key points:

• Managed by municipalities, with funding from premiums, taxes, and user co-payments.
• After an assessment, people are assigned a “support” or “care” level that determines the monthly budget for services.
• Services include home helpers, day centers, respite care, and nursing homes.

Foreign residents who are enrolled in Japanese health and long-term care insurance generally have the same rights as Japanese citizens, as long as they meet the age and need criteria.

For a step-by-step breakdown of eligibility, co-payment rates, and planning tips, see Healthcare for Retiree Expats: Elder Care and Long-Term Insurance in Japan.

Costs for dementia care

Under LTCI:

• Standard co-payment is usually 10% of approved service costs, rising to 20–30% for higher-income households.
• There is a monthly cap on out-of-pocket care costs; if you exceed it, you may get a refund.
• Medical visits (neurologist, psychiatrist, hospital tests) are paid separately under health insurance, typically 30% co-pay for under-75s and 10–20% for many people 75+.

Because the system is complex, many families work with a care manager (kaigo manager), who is assigned after you are certified for care, to design a care plan and choose services.

Community support: support centers, dementia supporters, and cafés

Regional Comprehensive Support Centers

Every municipality in Japan operates Community / Regional Comprehensive Support Centers (chiiki hōkatsu shien sentā). These centers:

• Offer free consultations for older adults and families
• Help with long-term care insurance applications and care plans
• Coordinate medical, nursing, and welfare services in the local area

There are over 5,400 such centers, and more than 7,000 including branch offices nationwide.

If you have a Japanese-speaking relative, they can often call or visit these centers to start the process. As an expat, this may be your best local contact point if you are caring for a parent in Japan but feel lost.

Dementia supporter program and “orange ring”

Japan runs a Dementia Supporter Program, where everyday citizens attend short courses about dementia and how to support affected people in the community. Graduates used to receive an orange wristband (“orange ring”); now many municipalities issue dementia supporter cards instead.

There are also “Team Orange” volunteer groups that organize local activities and support early-stage dementia.

As a foreign resident, you may not join every activity, but knowing these programs exist can make it easier to:

• Recognize supportive badges in the neighborhood
• Ask your city office about dementia-friendly shops, banks, and transport staff

For more on community life, see Making Friends and Building Community as an Expat in Japan.

Dementia cafés and peer groups

Across Japan, NGOs and local governments host dementia cafés and community “salons” where people with dementia and their families can relax, share experiences, and get information. Reports highlight these as key “sources of security” in dementia-friendly communities.

These cafés often:

• Serve simple drinks and snacks
• Invite nurses, social workers, or dementia specialists as guests
• Offer a place where memory problems are understood and not judged

If you or your family are feeling alone, your nearest Regional Comprehensive Support Center can usually tell you where local dementia cafés and groups meet.

Practical steps for expats supporting an aging family member in Japan

Step 1: Notice early signs and talk openly

Common early changes in dementia include:

• Repeating the same questions or stories
• Getting lost in familiar places
• Trouble handling money or schedules
• Sudden mood changes or withdrawal from hobbies

If you notice these, try to:

• Share your concerns gently but clearly with your parent or in-law
• Encourage a check-up at a familiar clinic
• Offer to go along or join by video if you live abroad

Guides like Communicating with Doctors: Language Tips for Non-Japanese Speakers and Overcoming Language Barriers at the Hospital: Using Interpreters and Translation Services can make these first visits smoother.

Step 2: Confirm insurance and residency status

Check:

• Is your family member enrolled in National Health Insurance or Employee Health Insurance?
• Are they paying Long-Term Care Insurance premiums (usually from age 40)?

This matters because dementia care relies heavily on these systems. If you plan to bring parents to Japan, then check out Dependents and Family Visas in Japan: A Practical Guide.

Step 3: Apply for long-term care certification

If a doctor suggests dementia or high care needs:

1. Contact your city hall or Regional Comprehensive Support Center.
2. Apply for nursing care certification (nintei shinsei).
3. An assessor will visit to ask questions and confirm what help is needed.

After approval, a care level is assigned and a care manager is appointed. This person becomes your main guide to services, so try to build a good relationship.

Complement this with Step-by-Step Guide to Japan’s Long-Term Care Insurance Application on your site.

Step 4: Build a care plan that fits your family

Things to consider:

• Does your parent prefer to stay at home as long as possible?
• Are you or your partner able to provide daily support, or do you live far away?
• Is your priority physical safety, social contact, or giving a spouse respite?

A typical plan may combine:

• Day-care twice a week
• Home helper visits for bathing and cleaning
• Occasional respite stays so family caregivers can rest or travel
• Regular visits to a memory clinic

For cross-border families, Healthcare When Traveling Abroad from Japan: Insurance and Practical Tips can help you manage trips while a parent is in respite care.

Step 5: Organize legal and financial matters early

Dementia can make it harder to sign contracts or manage money. Ideally:

• Discuss powers of attorney or similar legal tools while the person can still decide.
• Review savings, pensions, and life insurance to see what funds are available.
• Make basic plans for future housing and, later, funeral arrangements.

Articles like Funeral Arrangements in Japan: A Guide for Expats can help you think ahead without feeling gloomy.

Communicating with Japanese doctors and care staff

Even in English-friendly facilities, knowing some key Japanese terms helps:

• Dementia – 認知症 (ninchishō)
• Alzheimer’s disease – アルツハイマー型認知症
• Memory clinic – 物忘れ外来 (monowasure gairai)
• Long-term care insurance – 介護保険 (kaigo hoken)
• Care level – 要介護度 (yōkaigodo)
• Group home – グループホーム
• Special nursing home – 特別養護老人ホーム (tokuyō)

You can say:

• “My mother has memory problems and I’m worried about dementia.”
  • 母に物忘れが多く、認知症が心配です。
• “Can you explain the diagnosis and care plan in simple English?”
  • 診断と介護の計画について、やさしい英語で説明していただけますか。

Looking after yourself as a caregiver

Caring for someone with dementia is often a marathon, not a sprint. Research from Japan and other countries shows high rates of stress, depression, and physical health problems among family caregivers.

To protect your own health:

• Use respite services (short stays, day care) without guilt.
• Join support groups, including online international communities.
• Consider counseling if you feel overwhelmed; Mental Health for Expats: Counseling and Support in Japan and Teletherapy in Japan: Online Counseling Options for Expats explain your options.
• Keep regular check-ups for yourself as well; do not skip your own medical care.
