Two notebooks belonging to a notorious Japanese aggressor responsible for the brutal germ warfare in China during World War II have been found in Tokyo, a local daily reported Thursday.  

The notebooks were discovered at residence of a following of Shiro Yishii, head of the Japanese aggression army's Unit 731 that carried out a germ warfare in China before and during the war, which resulted in the deaths of many Chinese people from pest and cholera.

In case of being seized by US troops, Yishii entrusted the following to keep the notebooks at home right after the end of the war, the Asahi Shimbun said. But Yishii died in 1959 and never came to fetch them.

After analysis, the notebooks have been confirmed belongings of Yishii since some senior officials' residential addresses recorded in the books were high secrets of the Japanese militarism army during the period.

Written on the covers of the notebooks are "Note of war end, Aug. 16, 1945" and "Note of war end, Shiro Yishii" respectively, according to the newspaper. There are also abundant brachylogies and argots available in the notebooks.
