"We think now is the time that investors need to understand the handful of key legislative events set to occur during the next few years, as these actions will shape Japan's attractive integrated resort opportunity," says a 100-page analysis by Moody's on Japan's gaming developments quoted by Nasdaq website.
It also said Japan could quickly become the world's third-largest gaming market, earning revenue of $21 billion in 2024 - its first expected year of operation.
But the road to gambling in Japan is only partly paved. Japan's parliament wants to pass a bill that would lay out the industry structure, such as laws and regulations, taxes, licensing terms and measures against problem gambling and money-laundering. But before that, Japan also plans to pass a bill on gambling addiction.
"There is resistance by residents and politicians who are concerned about the social ills that can be caused by gaming," said Morningstar analyst Dan Wasiolek.
