Japan would establish an independent gaming regulator modelled on the authorities that police casinos in Las Vegas and Singapore under a draft plan to legalise gambling in a market seen as potentially the second largest in the world.

The policy outline, which was prepared by Japanese lawmakers who favour casinos, outlines broad standards for licensing and regulating casino operators and their partners.

After more than a decade of lobbying by lawmakers, a bill to legalise casino gambling is seen as having a good chance of passing in the coming months with the business-friendly Liberal Democratic Party in power and after Tokyo - a likely casino host - won the bid to host the Summer Olympics in 2020.

MGM Resorts International, Las Vegas Sands, Melco Crown Entertainment and Wynn Resorts are among the global operators that have shown interest in developing a casino resort in Japan.

Among the concerns lawmakers who favour legalising casinos believe need to be addressed is what measures will be taken to keep out organised crime, known in Japan as the “yakuza.”

To address those concerns, the draft plan calls for the creation of an agency that would have control over the issuing of licences and the policing of gaming operations.
