What is the age requirement for children to use child seats under Japanese Traffic Law?

In Japan, the law requires that children up to the age of six must be secured in a child seat while riding in a vehicle. This is designed to ensure their safety, as young children are particularly vulnerable in the event of a traffic accident. The regulations are in place to provide optimal protection and to accommodate the physical development of young children. By the age of seven, children are typically considered to be older and better able to use the standard seat belts safely, hence transitioning away from the mandatory child seat requirement. Understanding these regulations is crucial for compliance with Japanese traffic laws, especially for those living in or visiting the country.
