The Japanese government has not denied the possibility of allowing online casinos (also known as "onkaji") in the future, despite current regulations blocking their operation. This comes amidst growing interest in the economic potential of digital gambling. The idea is still in its early stages, with government regulators studying the potential impacts and necessary precautions for such an industry.

Online gambling remains a topic of controversy within Japan due to the country's stringent laws around gambling. Most forms of gambling are illegal in Japan, barring some exceptions like public sports, lottery, and pachinko. The prospect of online casinos brings into play social concerns around addiction and the integrity of the game, but it also opens up a potential new revenue stream, which has sparked interest.

Unlike Japan, online gambling is more widely accepted in the US and the EU, with regulations varying by state and country. These regions have found ways to balance the risks and benefits of the industry through licensing, regulations, and strict penalties for misconduct. The comparison serves as a reference point for Japan as it considers the future of its own online gambling industry.
