Beyond what is provided for in the preceding two Articles, transitional measures necessary for the enforcement of this Act (including transitional measures concerning penal provisions) are specified by Cabinet Order.

If five years have elapsed since this Act came into effect, the Government is to review the status of enforcement of the provisions as amended by this Act, and, when it finds it to be necessary, take the necessary measures based on the results of the review.
