Theme 3: 変わっていく人生観 — Research Subject: 高齢化社会 (The Ageing Society)

Welcome to your complete revision guide for 高齢化社会 (The Ageing Society). This topic sits inside Theme 3: 変わっていく人生観 (Changing outlooks on life) for the Pearson Edexcel A Level Japanese (9JA0) specification.

In Paper 1 (9JA0/01) Section C, you are required to write a research-based response of \(600\) to \(700\) characters in Japanese. To secure top marks in AO4 (Knowledge and Understanding of Japanese Society), you cannot simply write broad generalisations like "Japan has many old people." You must analyze specific demographic trends, social issues like isolation, changing family roles, and state-level policy solutions using precise vocabulary and verified facts.

Don't worry if this feels overwhelming at first! We will break down the essential data, cultural concepts, and essay frameworks into clear, digestible steps.

1. Demographic Reality: Japan as a 超高齢社会 (Super-Aged Society)

Japan is officially classified as a 超高齢社会 (chō-kōrei shakai — super-aged society). This means an exceptionally large proportion of the total population is aged \(65\) or older.

Key Statistics to Memorise:

・ Current Demographic Share (2024): \(29.3\%\) of the total population is aged \(65\) or older (a total of \(36.25\) million people).
・ Gender Breakdown: Men aged \(65+\) make up \(26.2\%\) of the male population, while women aged \(65+\) account for \(32.4\%\) of the female population.
・ Centenarians: Japan has recorded over \(95,000\) people aged \(100\) or older as of 2024.
・ Future Projections: According to official projections, the elderly ratio will rise to \(34.8\%\) by 2040 and reach \(36.3\%\) by 2045.

Analogy to remember: Imagine a room of \(10\) people in Japan today—almost \(3\) of them are over \(65\). By 2045, more than \(1\) in every \(3\) people will be an older citizen!

Key Takeaway: When introducing your research essay, use precise terms like 超高齢社会 and state that elderly citizens make up nearly \(30\%\) (\(29.3\%\)) of Japan's population.

2. 高齢者の孤立 (Isolation of the Elderly) & 孤独死 (Solitary Deaths)

As the population ages, living arrangements change, leading to severe social isolation (社会的孤立) and the issue of 孤独死 (kodokushi — solitary deaths).

Social Isolation & Living Alone:

・ Frequency of Interaction: Research shows that among elderly men living alone, \(15\%\) speak to only one person or fewer every two weeks.
・ Solitary Deaths (2025 Data): In 2025, \(76,941\) people who lived alone died at home. Out of these, \(76.6\%\) (\(58,919\) people) were aged \(65\) or older.

Community Prevention Measures:

To combat this severe isolation, local communities and research initiatives are setting up physical support networks:
・ Community Sheds (コミュニティ・シェッド): Gathering spaces such as the "Yoro-ya" (よろーや) in Kumamoto Prefecture allow elderly residents to participate in crafts, gardening, and casual social conversations.
・ Dementia Cafés (認知症カフェ): Local drop-in spots where people with dementia, their families, and local volunteers interact in an open, judgment-free environment.

Key Takeaway: Social isolation is particularly acute among single elderly men. Grassroots initiatives like Dementia Cafés and Community Sheds provide vital social contact to prevent kodokushi.

3. 家族による支援の変化 (Changing Family Support)

In traditional Japanese culture, elderly care was rooted in filial piety (孝行, kōkō) under the traditional multi-generational family structure (家制度, ie seido). Today, this dynamic has shifted drastically.

Changing Household Composition:

・ Elderly in Households: \(49.5\%\) of all households in Japan include at least one elderly person (\(65+\)).
・ One-Person Households: Among households with elderly persons, \(31.7\%\) are single-person households (単身世帯).
・ Decline of Multi-generational Living: Only \(20.2\%\) of elderly households consist of parents living together with unmarried children.

The Phenomenon of 老老介護 (Rōrō-Kaigo):

老老介護 (rōrō-kaigo) refers to situations where an elderly individual is cared for by another elderly person (typically an aged spouse or child).

・ \(65+\) Caregivers: In \(63.5\%\) of caregiving households, the primary caregiver is also aged \(65\) or older.
・ \(75+\) Caregivers: In \(35.7\%\) of cases, both the caregiver and the care recipient are aged \(75\) or older.

Memory Trick: Rō-Rō literally combines the kanji for "old" (老) twice. It means an old person caring for an old person.

Key Takeaway: Due to the decline of traditional multi-generational living, family care often falls entirely upon elderly spouses, resulting in high rates of rōrō-kaigo and caregiver burnout.

4. 社会的支援と政策 (Social Support and Government Policy)

Because family units can no longer shoulder the burden of care alone, the Japanese government has transitioned from "family care" to "socialised care" through legislation and community systems.

1. 介護保険制度 (Long-Term Care Insurance System - LTCI):

・ Implemented: Year 2000.
・ Purpose: Shifted the financial and operational burden of elderly care from family members alone to a shared social insurance system funded by public taxes and insurance premiums paid by citizens aged \(40\) and above.

2. 地域包括ケアシステム (Community-Based Integrated Care System):

・ Target Goal: Set for realisation by 2025.
・ Mechanism: Integrates housing (住まい), medical care (医療), long-term care (介護), and preventative care (予防) so that elderly individuals can continue living in their familiar hometowns within a \(30\)-minute radius of support.

3. 孤独・孤立対策推進法 (Act on Loneliness and Isolation Countermeasures):

・ Effective Date: April 1, 2024.
・ Focus: Promotes national and local public-private partnerships to tackle chronic loneliness and isolation as a national policy priority.

Key Takeaway: Social support in Japan relies on a tripartite foundation: the Long-Term Care Insurance System (financial & structural), the Community-based Integrated Care System (local infrastructure), and the 2024 Act on Loneliness and Isolation (statutory preventative action).

5. Exam Strategy: Paper 1 Section C Research Task

In Paper 1 Section C, you must produce a concise, well-argued response between \(600\) and \(700\) characters. Here is how to structure your answer to maximise your AO4 marks.

Common Pitfalls to Avoid:

1. Being Too Vague: Do not write "日本の高齢者が増えています" (Elderly people in Japan are increasing). Instead, cite specifics: "日本の総人口の\(29.3\%\)が高齢者であり..." (Elderly people make up \(29.3\%\) of Japan's total population...).
2. Pure Description without Analysis: Don't just list facts. Explain why a policy exists (e.g., LTCI was created because the traditional ie system declined and rōrō-kaigo increased).
3. Character Limit Penalties: Keep strictly between \(600\) and \(700\) characters. Writing under \(600\) lacks depth; exceeding \(700\) risks losing structure and focus.
4. Forgetting Research Signposts: Explicitly show the examiner that your points stem from independent study.

Essential Japanese Phrases for Your Essay:

・ Stating Research: 私の調査によると (According to my research...)
・ Citing Data Sources: 厚生労働省のデータによれば (According to Ministry of Health, Labour and Welfare data...)
・ Identifying Problems: この背景には、家族形態の変化や孤立の問題がある。(Behind this lies changes in family structure and issues of isolation.)
・ Concluding with Policy: したがって、地域包括ケアシステムのような社会支援が不可欠である。(Therefore, social support like the Community-based Integrated Care System is essential.)
