Shogun, Mustique

On an island already famous for its over-the-top exclusivity (Mick Jagger has a holiday home here, and Prince William and Kate Middleton came to celebrate her 30th birthday), the Japanese ryokan–style Shogun, which is 9,000 square feet, stands alone for its outlandish opulence. The house, built on five bucolic cliff-side acres on the western saddle of the island in 1980—and newly renovated this year—is a showcase for Japanese art and antiques, and sports two swimming pools, a private putting green, three vehicles (one Suzuki jeep and two open “mules”) and a game-fishing powerboat. Each of the nine silk-upholstered, shoji-screened bedrooms is named for a Japanese flower; most look over a 1,000-square-foot central pond, stocked with a small fortune’s worth of koi. mustique-island.com
