Japan's political parties are, for the most part, very small and very short-lived. This is largely because the National Diet is filled by a combination of proportional representation and first past the post elections, making it easy for a small party to get a foothold in the assembly, but difficult for a small party to become dominant. The Liberal Democratic Party is the only real exception to Japan's trend toward small parties.
