TOKYO OPENINGS: New store openings in Tokyo have been scarce on the ground lately but more than five months after the devastating earthquake struck northern Japan, retail activity appears to be percolating once again. On Friday, Bally designers Graeme Fidler and Michael Herz will host a cocktail to fete the Swiss brand's recently opened flagship in Ginza. Meanwhile, the Aoyama neighborhood is getting some fresh storefronts. Los Angeles-based designer James Perse is opening a boutique this Friday in a street behind the Comme des Garcons flagship. Perse said the store, which features a ping pong table on the second floor, evokes a Southern California feel: "comfortable, casual but sophisticated." Moncler is opening a flagship just around the corner next week in a spot formerly occupied by D&G. Moncler chairman and creative director Remo Ruffini will fly to Tokyo for the store's opening party August 31.
