In a detailed report on the potential for Japan’s gambling industry, UBS said it estimates a market size of $9.4 billion in 2020, the year it expects the first casino to open, growing to $18.4 billion by 2030. It expects three casinos to open initially and at least two further complexes after that. UBS said it expects the bill to legalise casinos to be passed by the end of June. “The lifting of Japan’s casino prohibition will give leading overseas operators an opportunity to develop a new market. On the other hand, it will also create concern among neighboring countries and regions as well as sectors over a loss of market share from increased competition,” the report said. UBS’s top stock picks based on Japan’s casino industry are Las Vegas Sands Corp., Melco Crown Entertainment, Genting Singapore, Sega Sammy HD, Kajima, Japan Airlines, H.I.S. In a separate report, Telsey Advisory Group put the potential size of the market at $23.8 billion.
