Government of Japan

The Government of Japan is the executive authority of Japan, a parliamentary constitutional monarchy in East Asia. It is led by the Prime Minister and the Cabinet, accountable to the National Diet, Japan's bicameral legislature. The Emperor serves as a ceremonial head of state. The government administers national policy across economic, social, and foreign affairs, including immigration and residency, managed largely through the Immigration Services Agency under the Ministry of Justice. Japan has historically maintained relatively restrictive immigration arrangements while introducing programmes to admit foreign workers in response to demographic ageing and labour shortages, such as specified skilled worker categories. Its policies and their outcomes are documented in official statistics and remain subject to public debate.
