Genting Singapore Plc is walking away from its casino joint venture on South Korea’s Jeju Island as it gears up for a possible integrated resort license application in Japan.

The casino operator announced over the weekend that it is selling its 50 percent stake to its joint venture partner, Hong Kong property developer Landing International Development Ltd., for $420 million—a “modest gain” relative to Genting’s contributions totaling $381 million.

With the Jeju casino out of the way, Genting said it will now focus on its existing Singapore operations while, at the same time, “enhance the balance sheet for a run at a Japan IR license.”

Casino operators have started lining up to gain Japan’s elusive approval for an integrated resort development following reports that Japanese lawmakers are renewing the push for casino gambling legalization. Aside from Genting Singapore, Hard Rock Café International, MGM Resorts International and Las Vegas Sands have expressed their interest in getting a casino license in Japan.
