What is the government system of Japan like?

The Japanese government, as in many democratic countries, is composed of a legislative branch, an administrative branch, and a judiciary branch.
Each of the branches is independent from the others in terms of power.
The Diet is vested with legislative powers, the cabinet with administrative powers, and the court with judiciary powers.
The execution of administrative powers is based on the "parliamentary cabinet system" in which the cabinet is organized by the Diet.
The prime minister is designated by the Diet and the state ministers are chosen by the prime minister.
However, unlike in some democratic countries such as the United States, the majority of state ministers are chosen from among members of the Diet.
This fact can obscure the line between the legislature and the administration.
