Women – although not so much an aspect of Japanese business etiquette as of culture, many Japanese men do not relate easily to women with authority in business and that can present problems for women executives from the US and Europe. To avoid being treated as an ‘office-lady’, I recommend that you wear shorter (or tied back) hair, trouser suits or longer skirt suits with seasonal colors as for men. Japanese women are very fashion conscious and many wear Gucci, Chanel, Prada etc. outfits to and from work (although most companies require their female staff to wear company uniform while working). Most Japanese companies do not allow female employees to wear jewelry, very short skirts or high-heeled shoes. Women too are not properly attired without Japanese business cards!  Article
