Supporting an event, water polo game analyses is executed by the scientific section of the Japanese Water Polo Committee, and the data is being offered to the athletes and the spectators at the venue. Moreover, the same data can be seen on a web site established for the game analyses. Also, statistical data of the games that aren't distributed at the venue has been uploaded to the web site. The purpose of this study is to examine the utility value of the web site from the number of access hits and from a questionnaire survey. 1) The number of access hits increases rapidly from the first day of an event, and it continues to a high total until the statistical data is completely uploaded. Of course, depending on the event, there is a difference in the number of total access hits. 2) The web site user would prefer to see more detailed data rather than quickly uploaded data. 3) The web site user would like to see the uploading of game reviews and game broadcasts, in addition to the current contents. 4) It will be suggested to examine charging for the data sheets and the software for the game analysis in the future.
