The Team

Masa Shimakawa


Driven by the importance of innovation, Chef Masa Shimakawa creates thoroughly original dishes using Western ingredients in Eastern style. Indoctrinated into the culinary arts as a dishwasher in his early years, the acclaimed chef quickly worked his way through the discipline, beginning with studies at Hakodate Professional Cooking School and a sushi-chef position in Tokyo. This was followed by work in Montreal, Chicago and New York before he found his way to Four Seasons Hotel Westlake Village.
