Understanding of Internet users for real-time precipitation or water level information was researched based on Internet questionary survey in February 2007. The percentage of recognition for “River Disaster Prevention Information”, administrated by River Bureau, was only 4.7%. It is hardly different from the result of similar survey in 2004. Even if real-time heavy rainfall disaster information Web pages were introduced to respondents, the answer with a clear use intention was about 10%. The use intention of cellular phone web pages was still lower. “The television is more useful for an emergency” etc. was mentioned as the reason. It is possible that even if well-known to these pages, many people may not use. There is no doubt about public presentation of information is important. However, it is also important to develop simple information communication system to general public for heavy rainfall disaster prevention.
