The University of Tokyo, Tokyo, Tokyo, Japan The collapse of the traditional Japanese household system and the subsequent social advancement of women has led supporting parents as a family matter, and led more men to assume caregiving roles; however, very few studies have fo- cused on sons’ care motivation. This study aimed to under- stand adult sons’ perceived care motivation and to examine the respective related factors of emotional attachment and reciprocity. A total of 1322 men (M [age] = 44.5) partici- pated in a web-based questionnaire survey. Perceived care motivation for providing five types of support (e.g., helping with daily activities and housework) to each parent and parent-in-law was assessed. Regression analyses revealed that emotional attachment with parents and parents-in-law predicted perceived care motivation for all types of support. Furthermore, the role of reciprocity was indicated by the as- sociation between rearing by mother-in-law and son-in-law’s motivation to provide assistance in financial matters, house- work, and visiting a hospital.
