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.
