The number of comprehensive health checks for 5-year-old children in Japan, commonly known as "5-Year-Old Checkups," is expanding across the country. These checks aim at early detection of health-related issues before children start school. The health checks cover several aspects, including physical health, cognitive development, and emotional well-being. The government is striving to conduct these checks universally across Japan, emphasizing on their importance in children's educational journey.

Japanese society highly values early detection and preventive measures in healthcare. The spread of 5-year-old checkups before school start echoes this value. Being a preventive measure, it contributes to healthier children and could lessen burdens on educational and healthcare systems. The public has been generally supportive, understanding the checks' role in shaping children's future and potential in society.

In the US or EU, child healthcare systems also include preventive measures such as regular health screenings, with a particular focus on early childhood years. However, the implementation varies across countries and states. Despite the differences, the shared objective across these regions is to ensure that children are physically and mentally prepared to start formal schooling.
