Non-delegation and the Constitution in Japan

Japan has a Coronavirus Special Measures Act(CSMA). Article 32 of the Special Measures Act delegates to a Cabinet Order the necessary cases for the Prime Minister to issue a state of emergency.
Article 32 of the CSMA stipulates that the government shall issue a declaration of a state of emergency and report to the Diet when the infection situation worsens, in accordance with the requirements specified by the Cabinet Order. When the government issues an emergency declaration, it must publicly announce the duration, area, and content of the emergency.
This paper deals with the issue of whether it is an infringement of the legislative power under Article 41 of the Constitution to set forth the requirements for declaring a state of emergency subordinate to the law, which has a great impact on the lives of the people.
