Muji to Go, Narita International Airport

Simplicity rules at the 750-square-foot outpost of Muji, the popular Japanese accessories giant. Glass-and-blond-wood shelves are stocked with a pared-down selection of the chain’s smartest travel merchandise: regulation-size refillable plastic bottles (perfect for shampoos and mouthwash), a cool portable unisex raincoat, and chic-simple umbrellas.
