In japan, the emperor, a hereditary ruler, serves at the head of state, while the people participate in governing and elected officials make laws. what type of government does japan have?
oligarchy, direct democracy. communist . parliamentary democracy/

From the description, it is clear that Japan’s type of government is (D) parliamentary. To be more specific, Japan is a constitutional monarchy – thus, the head of the state is represented by the monarch, which in the case of Japan, is an emperor, while the head of the government is represented by a prime minister.  

The parliament of Japan, more specifically the legislative body, is called The National Diet, which consists of a lower house called House of Representatives and an upper house called the House of Councillors.

in an absolute  monarchy, the  monarchrules as an autocrat, with absolutepower  over the state and government — for example, the right to rule by decree, promulgate laws, and impose punishments. the  monarch isnominally sovereign but the electorate, through their legislature, exercise political sovereignty.
