Although Japan has started her third major political reform in 1993, it's still on the way to its destination. However, from the processes of development and results, one can clearly visualize that these political and administrative reforms have changed the Japan's governing system from 'Centralization' to 'Decentralization', such as the model of decision-making being changed from the 'gigantic bureaucratic system' to an 'effective issue leading system'; party politics, also unavoidably, changed from 'monopolized party system' to 'two major-party system' which mainly consist of those multi small parties. Therefore, the ”two layer power structure” created by the factions of LDP (Liberal Democratic Party) is also tearing apart, not to mention the factions' influences. Instead, the chairman and the party cabinet have revived the strong leading style to make their own decisions in order to survive in new political structure in Japan.
