During summer holidays in Japan, grandparents often become temporary caregivers for their grandchildren leading to a unique challenge dubbed "grandchild fatigue." This societal phenomenon tends to surface annually, underscored by the extended holidays and the practice of entrusting child care to grandparents. The issue encapsulates a range of struggles, from physical exhaustion to generation gap related tensions.

In Japanese society, grandparents playing a significant role in childcare is commonplace, especially during the summer holidays when working parents cannot take time off. The respect for elders and the strong familial bonds are deeply rooted in the culture. However, the physical toll and generational gap issues that emerge invoke a debate around social and familial responsibilities.

In the US or EU, summer camps and day-care services are more prevalent, so grandparents may not have as significant a role in childcare during holidays. While grandparents do help with childcare, the level of involvement and expectations can be different compared to Japan. Elderly care and wellness are prominently discussed in these societies.
