Dementia is causing global concern with its massive impacts on affected individuals, families, society, and national economies. As the disease progresses, patients’ needs increase in number, depth, and breadth, covering physical, psychological, social, and spiritual domains. Care varies from place to place, from country to country and from east to west. To learn from some of these variations, we explored advanced dementia care in United Kingdom and Japan. Informed by an overview of literature on care of people with advanced dementia, we reflected on direct nonparticipant observations of care in urban areas of Northern Ireland and Japan. While we identified a common purpose to address the complex needs of people living with dementia, there were differences in the approach to care. Broadly, dementia care in United Kingdom tends toward person‐centered care with a strong interest in Advance Care Planning as part of a palliative care approach. In Japan, we found less evidence of early stage palliative care and more of family‐based decision making to inform care of older people. In both countries, dementia care varies regionally, being more available in some areas than others. International knowledge exchange and further comparative studies will help to improve care for people with advanced dementia, everywhere.
