The periods we will explore today will stretch from the Meiji restoration until the Manchurian Incident in 1931. The Meiji Period saw the rise of the emperor to power and Japan becoming an Empire once again.
The Taisho period saw the rule by a sickly emperor and the widespread democratization of the Japanese government.
These periods saw the modernization of Japan, transforming from a medieval society to an Imperial Nation-State in the style of A Euro-American empire. The problems that the Japanese EMpire would face were the same that all colonizing powers do, internal turmoil brought about by over expansion.
