Across Japan, the number of men who are becoming the main caregivers for their ailing parents is on the rise. Data shows sons are more likely to struggle in the role than other family members, and when that happens they can become frustrated and lash out. We look at the challenges faced by some male caregivers, including one of our own NHK directors, and consider what they can do to make their lives easier as they look after their elderly parents.
