Stations in Japanese metropolis are compounded with the commercial function. Station sign planning and indoor advertisement are intermingled in the public space. The present stations offset the communication effect by self-assertion such as a railroad company's advertisement, a business advertisement, a store signboard, a souvenir shop stand signboard, a clock, etc.. It is important that transfers acquire the information on the destination efficiently in a station yard. This study makes JR Tokyo Station a case study, and attempts an actual situation survey of a sign planning and an indoor advertisement as a fundamental study. Consideration for their coexistence is performed.
