What are reasons for the rapid expansion of Japanese imperialism in the 1930s?

The rapid expansion of Japanese Imperialism in the 1930s was driven by several key factors. Economic needs, particularly the desire for resources such as oil and rubber, fueled expansionist policies as Japan sought to secure raw materials for its growing industrial economy. Additionally, the rise of militarism and nationalist sentiments within Japan fostered a belief in the country's destiny to dominate Asia. Lastly, the political instability and weaknesses of neighboring countries provided Japan with opportunities to assert its influence and territorial claims through military aggression.
