Hataraki Man (働きマン, Hataraki Man?) is a manga by Moyoco Anno, serialised in the seinen magazine Morning. It has been adapted into a TV anime, which screened in Japan from October to December 2006 and a drama that aired from October 2007 to December 2007. The story centres on 28-year old Hiroko Matsukata, editor at the magazine Weekly JIDAI (週刊「ＪＩＤＡＩ」, Shūkan JIDAI?). Talented and hard-working, Hiroko's colleagues refer to her as Hataraki Man (literally "working man") because of her dedication to her job. But despite her successes in the workplace, she struggles with moments of self-doubt and with the challenge of balancing life and career.
