Japan's decentralized government allowed radical nationalists to impose their plans on the nation by creating a power vacuum with weak central control. This allowed extremist factions and military forces to gain influence and execute their aggressive and expansionist policies. The fragmented political structure also hindered effective countermeasures against radical elements, leading to a proliferation of nationalist ideologies and actions. Furthermore, the lack of strong central authority made it difficult to effectively suppress or restrain these radical nationalists, allowing them to exert their influence and achieve their goals.
