Final answer:
Before resuming military expansion, Japan explored diplomatic and economic strategies aimed at East Asian dominance, following Western models of industrialization alongside a nationalist desire for an empire, 'Asia for the Asians.'
Step-by-step explanation:
Before returning to military expansionism, Japanese leaders were also considering diplomatic and economic strategies as they sought to establish their country as the dominant power in East Asia.
Embracing Westernization, Japan underwent a transformation in economic, industrial, and military modernization and followed the path of European countries in embarking upon foreign conquests, particularly targeting Korea and Manchuria to build an empire.
The concept of 'Asia for the Asians' emerged alongside a growing ultra-nationalism among military officers who were dissatisfied with civilian leadership and sought to replace European influence in the region. Furthermore, during the American Occupation, Japan faced demilitarization and significant political and economic reforms geared towards preventing future militaristic endeavors.
