Abstract: Japanese politics is generally characterized by the long-term rule of the Liberal Democratic Party(LDP), with rare occurrences of governmental power shifts between political parties. However, due to the presence of different factions within the LDP, power shifts among these factions also constitute a form of governmental change. Since various parties hold distinct political ideologies, these ideologies often lead to policy fluctuations during power shifts. Consequently, both governmental power shifts and policy changes can trigger a “pendulum” phenomenon in politics. Specifically, in the parliamentary politics of Japan, the ruling party and the opposition parties exhibit a swing from “one-party dominance” to “ruling coalition”, and then back to “one party dominance” through the “two major parties”. Within the LDP’s political landscape, this is manifested as a shift in dominance between the party‘s conservative right-wing and conservative liberal factions, presenting a “pendulum” phenomenon. The current cabinet led by Prime Minister SnaeTakayichi has also demonstrated a shift from conservative liberal dominance to conservative right-wing dominance, thereby causing Japanese parliamentary politics to once again exhibit the “one-party dominance” phenomenon, characterized by a “pendulum” phenomenon.

Key words: “pendulum” phenomenon, the conservative right, the conservative liberals, right deviation
