Lawrence Ho, son of Macau gambling tycoon Stanley Ho, plans to invest more than $5 billion in Japan if Melco Crown Entertainment Ltd. receives permission to build a casino here as he sees constraints on development at home.

Ho's maneuver to build projects in the world's third-largest economy is part of his strategy to expand overseas for future growth, as government policies, limited land and a labor shortage in Macau could eventually restrict gaming development.

"We still have the most eggs in the Macau basket," Ho, co-chairman of Melco Crown, said in an interview in Tokyo on Saturday. "Given the Macau government and the Chinese government want to control the growth rate," the company is seeking other opportunities outside the city, he said.
