THE STYLE GUIDE FOR REPORTING ON JAPAN, AS ACTUALLY PRACTICED: Our Man provides it:

2. Do not use pictures of Japanese people behaving normally, such as shopping at CostCo, walking around IKEA or eating a hamburger, as this will imply to potential readers that you don't know the real Japan. As everyone knows, the real Japan is only evident in pictures of geisha, sumo wrestlers and toothless grinning old men, or if 19 and a beddable girl, in cosplay gear, or French maid outfit pouting for the camera making peace signs with her other nubile friends. Bonus points if they are in high school uniforms. Other acceptable cover art include blurry shots of commuters, female fashion victims walking on zebra crossings in the rain, or robots/people in multicoloured motorbike helmets.
