Summary

The purpose of this study was to document the Tama River—how it was utilized—in the year 2010 in order to preserve records for future generations. This was a study planned and implemented as a continuation of the “Campaign to Document the Tama River in the Year 2000” carried out ten years ago. From January to October 2010, four surveys were conducted. We compared the state of the Tama River of ten years ago with its current state. The record will be passed on to the next generations.



The surveys were conducted mainly in areas under the direct jurisdiction of the Tama River Class 1 Water System (approximately 62 km of the main river). Groups were assigned to each km post set up on the right and left banks. 360-degree panorama pictures were taken and surveys were conducted to find out how the riverbed was used. The surveys were mainly carried out by residents of the basin, NPOs, and university students. The four surveys had the cooperation of 176 participants. For every survey, we set up a theme based on the timing of the survey and carried out a special survey. Similar to the study in 2000, we gathered video images for the ten years, and edited them into digital data. The river utilization study results, special survey results, and list of image materials were collectively published as activity reports.



This time, we made new appeals to universities that had campuses in the Tama River basin to solicit their participation. A total of 29 students from five universities participated as researchers. As a collaborative program for the young people who will be shouldering the activities of the next generations, as citizens and residents, this study provided the opportunity for exchanges, enlightenment, and development of networking programs. It also contributed to river development and environmental management. It is also hoped that this kind of scientific research by citizens and residents will spread to other rivers in the future.



The digitalized images and information materials are shown regularly at two exchange spots along the Tama River with the hope to heighten the citizens’ interest in the Tama River.



We have now collected basic information and images of the people’s use of the Tama River in 2000 and 2010. We have great expectations for the young generations who participated in this study to conduct similar studies in the next five, and then ten years.
