Japan set up its first consulate in China in 1872 in the Shanghai Public Concession.Since 1884, Japan has dispatched police officers to the Shanghai Consulate General under the pretext of protecting and banning overseas Chinese.Japan has set up various police agencies such as police stations, police departments, dispatch offices, police stations, branch offices, and the “Central Police Department” inside and outside the consulate. The Shanghai Consulate has a maximum of 25 police agencies and 220 police officers. As the establishment of these police agencies has no legal basis, their existence and their activities are null and void.Initially, the Shanghai consulate police only engaged in the “protection and ban” of Japanese overseas Chinese. Since the Revolution of 1999, he has been mainly engaged in intelligence activities on the Chinese political situation. In particular, after the September 18th Incident, the Japanese Consulate General in Shanghai set up the largest intelligence agency in mainland China, the “Extra High Police Section” (referred to as “Extra High Section”, externally known as “Second Section”). The “super high police” actively monitored and banned the resistance movement of the Chinese people, and publicly searched and arrested the anti-Japanese people in various countries with guns.These police officers have been present since the surrender of Japan in 1945, during which time they committed unforgivable crimes of aggression in China.
