Mobile social media generate valuable data for analyzing human behavior and events in the real world. In this study, we developed a distributed system for collecting geo-tagged data from Twitter. The proposed system can collect several times as much data as commonly used methods. We also developed a spatio-temporal visualization tool for displaying the collected data. We conducted a data-collection and visualization experiment in central Tokyo and showed that the collected data reflected many events in the real world.
