Promotion of Service-Related Measures

In addition to steadily implementing infrastructure-related measures such as the construction of river control structures, the Bureau also takes service-related measures, including providing information on rainfall and river levels and broadening the public interest in and knowledge of rivers, to protect the lives and livelihoods of residents from disasters such as heavy rains, floods, storm surges, and landslides.

Providing River-Related Information

Providing Information via the Internet and Other Means

On the website of the Tokyo Metropolitan Government Integrated Flood Prevention Information System, the TMG provides information concerning flood risk, including rainfall, river levels, river images from monitoring cameras, and flood forecasts.

Information on flood risk is also provided via Twitter.

Broadening the Public Interest in and Knowledge of Rivers

The Bureau implements various measures to increase residents’ interest in rivers and make them more aware of the dangers of floods, sediment disasters, and water accidents.

In July, which is designated as River Month, a wide range of events are held every year, including riverside walking tours, study tours to river control facilities, trash pickup events, exhibitions, photo contests, and symposiums.
