Japan is leading the charge with preventative safety measures in underpasses for the first time ever. The local government has induced these precautionary rules to enhance public safety and improve underpass usage conditions. The regulation includes maintenance rules for underpass safety, an issue looked upon with increasing gravity following numerous accidents and events in recent years. This implementation was rolled out contemporaneously across the country.

In Japan, underpass safety has become a pressing issue due to an increase in accidents and incidents associated with its use. As they are largely used by pedestrians and motorists, a strong emphasis on their safety and responsible usage is a reflection of Japanese societal values of public safety and cleanliness.

In the US or EU, while there are regulations in place for underpass safety, comprehensive and uniform preventative measures like those just implemented in Japan are yet to become a common occurrence. The new regulations show a proactive approach to infrastructure maintenance which is required globally.
