The present invention provides a position-related information registration apparatus, a position-related information registration system and a registration display system. A portable information terminal (70) (position-related information registration apparatus) accesses a geographic information management server (60) (key word information storage unit) which performs related storage on each geographic key word (key word for retrieval) and each piece of position information, thereby acquiring position information (corresponding position information) which corresponds with the key word for retrieval from the key word extracted from the content of a registrated object for retrieval. Additionally, the portable information terminal (70) transmits registration request for registrating the information in which the content and the corresponding position information are related to content-related position-related information to a spatial tag information management server (position-related information management server)(50) besides the content and the corresponding position information, and registrates the spatial tag information to the spatial tag information management server (position-related information management server)(50).
