The intervention tore Japan's wartime unity to shreds, leading to the army and government being involved in bitter controversy and renewed faction strife in the army itself. The official conduct of the Siberian Intervention was later bitterly attacked in the Japanese Diet, with the Army being accused of grossly misrepresenting the size of the forces sent, misappropriating secret funds, and supporting figures such as lieutenant general
Roman von Ungern-Sternberg, rumors of whose atrocities had reached the press.
Japanese casualties from the Siberian Expedition included some 5,000 dead from combat or illness, and the expenses incurred were in excess of
¥900 million.
