摘要

A spot information retrieving device (120) sends a retrieval request adopting an arbitrary shop or various facilities (as will be called the 'spot') from a sending unit (121) to a spot information providing device (110). The spot information providing device (110) retrieves, when it receives the retrieval request at a receiving unit (111), the information on the spot at a spot retrieving unit (112), and retrieves the information on such other spot (as will be called the 'relative spot') at a relative spot retrieving unit (113) that the retrieving device having made the retrieval request with the same key word will make a retrieval request highly possibly. Each retrieved information is sent by a sending unit (114) to the spot information retrieving device (120). In this spot information retrieving device (120), a receiving unit (122) receives each information sent from the spot information retrieving device (120), and an output unit (123) outputs the information.
