Continuity and Change in Party Politics in Japan, Taiwan and South Korea

The 2012 elections in Japan, Taiwan and South Korea exhibit both long-term trends and short-term variations in each country's political landscape. All three societies are moving towards two-party competition lately, thanks mostly to the mixed-member majoritarian system adopted for legislative elections, despite the social cleavages that provide, to varying degrees, niches for small parties. The cleavage structure coupled with the electoral system largely explains the changing political landscape in these societies.
