Factions are an accepted part of the Liberal Democratic Party (LDP), the ruling party of Japan, which began with eight formal factions when it was first formed by merger in 1955. A political faction may be defined as a sub-group within a larger organization. While factions characterize other political parties in Pacific Asia, Japanese factionalism is distinguished by its stability and institutionalization. Although factions reconstitute themselves from time to time, the habatsu active today can be traced back to their 1955 roots, a testament to the stability and institutionalized nature of Liberal Democratic Party factions.

The Liberal Democratic Party , frequently abbreviated to LDP or Jimintō (自民党), is a major conservative and Japanese nationalist political party in Japan.
