Japan’s bill to legalise casinos is looking to be in line with what has been previously reported.

A draft secured by Bloomberg shows smaller regions being permitted to have casinos in addition to the big cities. Initially only a few casinos would be allowed so the country can gain experience and see how they fare.

Although Japan has been considering casinos for years, some are now pushing to have casinos opened in time for the 2020 Olympics in Tokyo. All major operators are interested in developing there, including Las Vegas Sands, Wynn, Caesars, SJM, MGM Resorts and Melco Crown, along with a handful of Japanese companies.

Estimates on how much revenue Japanese casinos could bring in range from $8bn a year to as high as $20bn just for Tokyo and Osaka combined.
