In 2004, Takayama opened his eponymous restaurant, Masa, in New York City. Located in recently constructed Time Warner Center, it had a 26-seat dining area. The idea for the location came from fellow chef and admirer Thomas Keller, who was opening his own restaurant, Per Se, in the complex. Continuing the ideas he developed in Los Angeles, Masa continued to serve only an omakase menu, tracking his customers' meals and reactions, and sourced 90% of his fish from Tokyo's Tsukiji fish market.
