 Declaration of individually selected "shi" and changes of given name initially (in February 1940) were conducted on the basis of voluntary notification.However, at the April prefectural governors' meeting, because of instructions such as "Special consideration should be taken so that the "shi" registration of all households can be completed by the coming July 20" the administration began to seriously promote the policy, and as a result, starting from April, the number of households registering individually selected "shi" began to rise sharply.As of April, only 3.9% of all households had provided notification for creation of a "shi", but by August 10, that figure had risen to 80.3%.
