The map, 108.5 centimeters long and 79.5 centimeters wide, was brown due to aging and a little broken along the edges. But despite its condition words on it could still be clearly identified and it carries 298-word "imperial edict" upon enthronement of the "emperor." The editor was named Nobuharu Kojima.

This is the first map ever found with words like "commemorative map for enthronement." Japanese invaders propped up Aisingiorro Puyi, the last emperor of the Qing Dynasty (1644-1911), in 1932 to establish a so-called Manchuria State in the three Chinese provinces in the northeast. The puppet state was used as the headquarters by the Japanese to continue to invade China.

The establishment of the puppet state was also verified by a Japanese soldier whose diary was left in Harbin, capital of Heilongjiang Province in northeast China.

The diary written by Sueta Murakami, who wrote in detail how Japanese troops forcibly occupied land in northeast China, stole its resources and migrated Japanese people to China for further exploitation.

Murakami recorded his own experiences within less than two months on 30 pages of the 140-page notebook.

Zhang Yifeng, 74, found the diary in August, 1945 in an abandoned barrack, once used by Japanese troops, which retreated when the former Soviet Union army launched a large-scale military attack against them.
