The article discusses the issue of cyclists using sidewalks and whether Japan's Blue Ticket System —a form of penalty system for rule violations— is effective. This issue has arisen due to increased instances of collision and conflict between pedestrians and cyclists on Japan's sidewalks. Authorities and city planners are looking for ways to address the problem, such as redesigning roadways or refining the regulations concerning bicycle riding on sidewalks.

In Japan, cyclists are allowed to ride bicycles on sidewalks under certain conditions. However, this has resulted in unintended issues, such as conflicts with pedestrians. The society is divided between preserving the convenience of cycling and ensuring pedestrian safety. The Blue Ticket System, which penalizes offending cyclists, is in focus as authorities look for ways to balance these aspects.

In the U.S. or EU, riding bicycles on sidewalks is generally prohibited, with most cities encouraging cycling on roads or designated bike lanes. They see it as a way to ensure both cyclist and pedestrian safety. Japan's issue of safeguarding both parties while managing urban spaces is a distinct challenge, highlighting differences in urban infrastructure and societal norms.
