In 4 sentences, summarize how Japan’s decentralized government allowed radical nationalists to impose their plans on the nation.

Japan's decentralized government allowed radical nationalists to impose their plans on the nation due to several factors. Firstly, the fragmented power structure of Japan's government allowed for a lack of central control, making it easier for radical nationalists to gain influence within certain regions. Secondly, the decentralization led to a lack of coordination and communication between different levels of government, making it difficult to counter or regulate the actions of radical nationalists. Thirdly, the absence of a strong central authority made it challenging to enforce laws and regulations, facilitating the implementation of radical nationalist policies. Lastly, the decentralized government system created a breeding ground for radical ideologies to flourish, as regional autonomy allowed for the incubation of extremist ideas without immediate intervention.
