The district of Roppongi in Tokyo has seen a consistent rise in the number of "illegal taxis" operating within its boundaries. These taxis have been found flouting regulations set by the Japanese transportation authority, creating a nuisance and posing a potential threat to public safety. Local law enforcement has been made aware and is now ramping up efforts to curb this problem.

In Japan, adherence to laws and regulations is deeply embedded into the fabric of society. The increase in "illegal taxis" not only disrupts harmony but is also seen as a breach of public trust. As Roppongi is a popular entertainment district known worldwide, the impact of such developments can tarnish its reputation and is of significant concern to both the locals and the government.

Unlike in Japan, where taxi operations are strictly regulated at the national level, the US and EU primarily rely on city or state/provincial regulations, which may vary widely. In case of similar issues, these Western countries typically face challenges with ride-hailing services like Uber or Lyft flouting local regulations, rather than traditional taxis.
