For generations, Japan, a devoutly spiritual society, is closed to the outside world, but by the late 19th century, the country emerges as a budding regional power, enticed by the promise of modernization and commercial trade. After triumphing in clashes with neighboring China and Russia, Japan begins the 20th century with continued growth and militarization. In 1924, a new emperor, Hirohito, ascends to the throne, and is largely swayed by Imperial Army and Navy leaders tethered to a fervent belief in Japanese racial superiority and a greater destiny. With scarce natural resources to support Japan’s booming population, many begin advocating an expansion of the empire, particularly on the Asian mainland, where China is immersed in civil war.
