A license is needed to undertake certain development actions.

When selling residential lots and houses, or undertaking development actions (including construction) for facilities that house people who need support in case of a disaster (social welfare facilities, medical facilities, etc.), a license is needed to ensure safety.

Designation of these areas is intended to restrict the construction of buildings in dangerous places.

Construction of a house is subject to approval of structures/regulation of structures.

Approval of structures is needed to ensure that the structure of a house can safely withstand the force of sediment, etc. that is estimated could act on the house.

When constructing a house, it is necessary to set up strong walls or retaining walls that can withstand the force that is estimated could act on the house.

Advice is given to relocate buildings, etc.

The prefectural government may advise owners of buildings that may suffer great damage, etc. to relocate such buildings. Financing and other support programs are available to those who relocate such buildings.

When there is no chance of ensuring safety by reinforcing buildings, etc., advice may be given to relocate such buildings.
