In this research, we focused on how to establish knowledge-sharing system by using websites named “Sato-net” in depopulated rural areas. We investigated 3 websites, which were developed and deployed in 3 elementary school districts in Sasayama City to disseminate information of these districts and to vitalize communication through the websites. We used log-data of Sato-net and access-analysis data by ‘Google Analytics’. As a result, we found that Sato-net is efficiently used to post notifications of events in those districts. Nonetheless, it is not used to vitalize communication and knowledge sharing online. In conclusion, we discussed how to improve them to take advantage of such websites in depopulated rural areas.
