Caring culture is a concept embodying the perceptions and caring practices of caregivers, acknowledging the unique role of cultural beliefs in shaping behavior. A qualitative descriptive study with 13 caregivers of adult family members with a cancer diagnosis in Japan was conducted to gain insight into perceptions and experiences surrounding caregiving. Several major categories were identified, representing rarely reported cultural constructs of high cultural value for the Japanese: On—repayment for what the patient has given, Caregiving as performing a socially expected role, Enryo/meiwaku—restraint in asking for help, Family decision making reflecting strong bonds, Omoiyari—empathizing with the patient’s feelings, and Inori—praying to myriad gods and ancestors. The Japanese cultural construct of ie (the strong relationship to family lineage and spiritual connection to past and future generations) is helpful in understanding these categories. Invisible yet powerful cultural constructs permeated caregiving practices. Insights from Japanese cultural concepts and beliefs may foster sensitivity and individualized care in diverse settings, cultures, and societies.
