"Starting multiple wars .." Had nothing to do with Europeans and gunboat diplomacy and colonialism? Have never been fond of imperial Japan and their atrocious behavior in Asia but it is quite disingenuous to consider Japan's behavior only from the 1930 and onward. To fairly consider the matter it is necessary to broaden the scope both in terms of nations involved and the timeline. An honest consideration of the historic events likely should start with the Opium War.
