Japanese authorities are facing difficulties in making the population aware of the 30 km/h speed limit on residential roads. Despite efforts to curb speed-related accidents, a significant portion of drivers remain oblivious or indifferent to the enforced regulation. Steps are now being taken to increase visibility and understanding of the speed limit, using a variety of strategies from signage to education.

In Japan, safety is a paramount concern in society. With busy cities and dense populations, issues such as traffic rules and road regulations become directly linked to people's welfare. The decrease of the speed limit and public awareness about it has been perceived as a responsibility shared by the government and citizens.

In the US and EU, strict adherence to speed limits is typically enforced and widespread awareness campaigns have been used to ensure drivers understand and follow these limits. Both regions have been successful in instilling a sense of responsibility and awareness in drivers through stringent traffic laws and penalties.
