I want to know the answer to the following question:
What was the reason Japan gave for the war?
All the background I'm provided with is that "Japan used the name Greater East Asia War (大東亜戦争, Dai Tō-A Sensō?), as chosen by a cabinet decision on 10 December 1941, to refer to both the war with the Western Allies and the ongoing war in China.". Is that enough to answer the question?
