Understanding Autonomy in End‐Of‐Life Dementia Care: Cultural and Ethical Perspectives From Japan

1. Background

End‐of‐life care is deeply shaped by culturally embedded conceptions of life and death, and this is especially relevant for persons living with dementia, whose decision‐making capacity tends to decline toward the end of life. In Japan, these challenges are shaped by a sociocultural context in which family involvement in healthcare decisions is both expected and institutionally embedded. While recent policy initiatives have promoted advance care planning (ACP) to support patient preferences, its implementation in dementia care remains complex (Ito et al. 2026).

2. Experience in Japan: How Autonomy Is Perceived and Practiced

Despite these policy advances, ethical understanding has not always kept pace, creating confusion among both professionals and the public.

A 2024 national survey revealed that 70% of Japanese people endorsed advance directives and proxy designations, yet most resisted making such arrangements legally binding. Many preferred to let family members make final decisions without formal designation. This pattern reflects the Japanese cultural norm that “If our hearts are in sync, we understand without words.” The cultural preference for implicit understanding clashes with modern medicine's demand for explicit, documented decision‐making intended to preserve autonomy even after capacity is lost.

Surveys illustrate how this preference operates in end‐of‐life decision‐making. Sixty percent of older adults have never discussed end‐of‐life wishes, though many believe their families know them. In contrast, 77% of adult children report never hearing their parents' wishes; nevertheless, nearly half believe they know what their parents wanted (Shimada 2015). When silence replaces conversation, is autonomy preserved through trust—or lost through assumption?

Professional understanding lags as well. In our survey of 549 healthcare professionals, 86% believed families had legal authority to consent on behalf of adult patients, though no such authority exists in Japanese law. About 30% regarded a DNAR order issued after family consultation as ACP, about half regarded ACP as a process for forgoing active treatment, while 81% considered family‐only discussions as “shared decision‐making.” These findings suggest that both conceptual and practical confusion remain pervasive across professional groups. Notably, equating ACP with treatment withdrawal, when combined with ambiguous legal frameworks, risks undermining patients' fundamental rights to receive care. Clearer ethical and legal guidance is urgently needed in clinical practice.

3. An Ethical Debate About Autonomy in End‐Of‐Life Dementia Care

The Japanese experience may reflect broader ethical challenges observed across parts of Asia. First, there is no shared conceptual framework for autonomy in Asia. Western bioethics prioritizes self‐determination, emphasizing independence, informed consent, and legal safeguards. In contrast, many Asian societies value harmony, filial duty, and collective responsibility (Shirahama 2001). These differing moral foundations lead to distinct interpretations of what it means to “respect autonomy.”

Second, empirical research on autonomy among people with limited capacity remains scarce in Asia (Ito 2025). Most studies address clinical procedures or symptom management rather than ethical and cultural dimensions. Few explore how autonomy functions when cognitive decline blurs the boundaries between patient, family, and professional decision‐making.

Third, sociocultural realities complicate ethical ideals. Traditional family support systems are eroding: the assumption that family members can represent the patient's will is no longer universally valid.

Similar demographic shifts are occurring in South Korea, China, and other rapidly aging societies. Thus, autonomy cannot simply be equated with self‐determination or family harmony—it must be understood within changing social ecologies. Furthermore, mental health conditions including dementia intensify ethical tensions. As cognitive capacity declines, reliance on family decision‐making often increases, heightening the risk that patient preferences may be overridden. Our vignette study in Japan illustrates how such family‐centered norms play out in practice: family opposition sharply reduced professional support for honoring patient wishes, particularly when dementia was involved. This dynamic, in which vulnerability shifts the moral weight from autonomy to protection, represents a shared challenge across Asian contexts. These tensions raise a difficult ethical question: does diminished capacity justify prioritizing family wishes over patient rights, or does ignoring patients' vulnerability fail to respect autonomy?

In cultures where self‐determination is not regarded as the supreme principle, respecting autonomy requires navigating conflicting wishes, family pressures, cultural expectations, ethical duties, and the vulnerabilities of both patients and professionals. This contrasts with Western bioethics, where autonomy, independence, and dignity are equated. In many Asian contexts, the involvement of others in decision‐making is not necessarily perceived as intrusive; rather, autonomy is mediated through family relationships, social harmony, and implicit trust. At the same time, such relational dynamics can also function as a means for individuals to evade direct responsibility for their own decisions. These differences demonstrate that ethical and legal frameworks are inseparable from cultural norms. The concept of relational autonomy, which recognizes the social conditions that enable or limit self‐determination, and emphasizes relationships that foster autonomy as part of therapeutic practice (Buedo and Daly 2024), may resonate with Asian understandings of autonomy.

4. Future Directions: Toward Collaborative and Culturally Grounded Models

Neither Western individualism nor Asian collectivism alone can resolve these ethical dilemmas. Individualism emphasizes legal authority and self‐determination, whereas Asian traditions stress harmony and contextual ethics. Yet both perspectives, when taken in isolation, reveal ethical blind spots: one tending toward moral rigidity and the other toward moral diffusion. The challenge is therefore not to choose between them but to weave their strengths into a more balanced and dialogical ethical framework. The future lies in developing integrative models that combine ethical clarity with cultural sensitivity.

For the Asia‐Pacific region, the next step is to cultivate culturally grounded frameworks of autonomy through shared conceptual understanding, collaborative research, and education that bridges ethics and cultural competence. Such efforts should aim to safeguard individual rights while recognizing family involvement as an ethical resource rather than an obstacle. Japan's experience illustrates both the possibilities and limitations of autonomy in aging societies. It shows that autonomy can coexist with interdependence when trust, respect, and open communication are fostered among all parties involved. The broader lesson for the Asia‐Pacific region is that autonomy must be reframed as a relational practice, anchored in cultural realities yet firmly committed to protecting the dignity of the most vulnerable.
