General Tojo Hideki's granddaughter insists that Japan fought a war of self-defence

Fumimaro Konoe who was the prime minister when Guāndōng Army invaded China without approval/order in 1937.

Does this refer to what the Wikipedia says on Fumimaro Konoe in the following ?

After the Marco Polo Bridge Incident in July 1937 and under pressure from hard-liners, his cabinet agreed to expand operations in China and handed the entire conduct of the conflict in China to the military leaders to progress without government oversight.

That does not stand coherent with James L. McClain's account in Japan: A Modern History, W.W. Norton & Company, 2002, Ch. 13, Japan Enters War:

Konoe's cabinet issued official approval to dispatch three additional units to China, July 27, 1937, at the request of the military in the hope of subjugating Jiang Jieshi's army through resolute military action.

August 14, 1937, the Japanese cabinet approved additional reinforcement troops to China; Prime Minister Konoe declared, 'China has arrogantly violated the ritual protocol, and Japan is obliged to take resolute action to chastise the cruel Chinese.'

Why is it that certain revisionist historians try to portray Konoe and his cabinet's role in the 2nd Sino-Japanese War as something they cannot be responsible for because they were dictated by the military ? How would that help lessen either Konoe or Tojo's guilt in the International Military Tribunal of the Far East ?

This is genuinely odd and illogical, when China, Korea, Taiwan, and other countries are ready to accept the past and move on into a peaceful future in which past enemy countries can coexist and prosper, that Japan alone goes on to embellish its past seeking absurd justifications for the wrongs, when such distortions can only raise eyebrows ? Why provoke when it can only bring back horrible memories and more shame to Japan ? Don't they realize that a misrepresentation will demand corrections ?
