Japan's decentralized government allowed radical nationalists to impose their plans on the nation by weakening the power of the central government and giving more autonomy to local governments and military factions. This created a power vacuum at the national level, allowing radical nationalists to exert their influence and implement their ideologies. Moreover, the lack of strong central control made it easier for these radical nationalists to manipulate and coerce local governments and military factions to support their agenda. Additionally, the decentralized government structure made it difficult to coordinate and implement effective resistance against these radical nationalists.
