### a. Fundamental Countermeasures against Sediment-related Disasters

Large-scale sediment discharge from devastated mountainous areas can cause serious damages to important community facilities such as downstream towns, roads, and railways. Construction of sediment-related disaster prevention facilities is being promoted to prevent large-scale sediment discharge from devastated mountain areas and riverbed rise in the downstream area, and to protect lives, property, and important community facilities from the damages by sediment discharge.

### b. Emergency Countermeasures against Sediment-related Disasters in Sediment Disaster Affected Areas

In order to ensure safety and security, and to maintain and promote socio-economic vitality in the areas where sediment-related disasters caused loss of life and great damages to people's living, concentrated construction of sediment-related disaster prevention facilities for preventing recurrence of disasters is being promoted.

### c. Countermeasures against Sediment-related Disasters to Protect Those Requiring Assistance during Disasters

People requiring assistance during disaster such as the elderly and children who cannot evacuate by themselves are liable to suffer the damages by sediment-related disasters. Among the dead and missing of sediment-related disasters, the percentage of people requiring assistance is high. So, in order to protect social welfare facilities, medical facilities, etc., for people with special needs, construction of sediment-related disaster prevention facilities such as sediment control dams is promoted in a focused manner.

Also, based on the “Act on Promotion of Sediment Disaster Countermeasures for Sediment Disaster Prone Areas (Sediment Disasters Prevention Act)”, the construction of facilities where people require special assistance is restricted in special sediment-related disaster hazard areas, and also matters concerning facility names, locations and information about sediment-related disasters are defined when making municipal disaster prevention plans. Considering the above, combination of structural and non-structural measures are being promoted.

### d. Countermeasures against Sediment-related Disasters for Urban Areas Near Mountain Base Slopes

For urban areas near mountain base slopes, forestry bands are fostered as green belts on the mountain base slopes adjacent to urban areas to enhance sediment-related disaster safety and maintain and create urban environments and landscapes with abundant greenery.

### e. Sediment Disaster Measures for Slopes Near Roads

Slope disaster prevention measures are taken for the slopes which have a risk of landslide near roads.

### f. Countermeasures against Sediment-related Disasters to promote Regional Disaster Prevention

In hilly and mountainous areas at high risk of sediment-related disasters which has a large impact on community people, construction of sediment disaster prevention facilities for protecting people’s lives as well as maintaining the important facilities such as evacuation shelters, evacuation routes, and town offices, that play an important role in regional disaster prevention is promoted for sustention and development of regional society.
