Don't call it fast food.

New York-based Bareburger, which opens its first restaurant in Tokyo this weekend, says it aims to penetrate the competitive Japanese market by focusing on organic patties and healthy vegetables.

Bareburger — whose gourmet burgers will be priced at ¥1,500 and upward — launched in the United States in 2009 and now operates 26 outlets in the U.S. and Canada.
