Senbu


The term senbu was used by the Imperial Japanese Army to refer to psychological warfare operations intended to pacify local populations and accelerate the process of Japanization.

Summary

The first senbu team was organized in 1932 by, a civilian employed by the Kwantung Army, as part of the preparations for the Battle of Rehe. The term comes from the envoys dispatched in ancient times by Chinese states to maintain control over regions destabilized by war.
Remnants of defeated Chinese armies frequently broke apart into marauding gangs of honghuzi who terrorized the rural population. This, combined with reports of violence against civilians by Japanese forces as well as the general chaos that followed the fires of war, contributed to panic and brought about a collapse of functioning society as masses of civilians fled to urban areas where they could expect protection by garrisoned Japanese troops. According to the scorched earth policy of the National Revolutionary Army, retreating Chinese forces routinely destroyed the homes, property, and food supplies of local people. It was not uncommon for Chinese soldiers to simply murder locals in order to prevent them from assisting the Japanese.
In the aftermath of this, senbu teams following the main Japanese force would, through the distribution of humanitarian aid and the implementation of Japanese-funded social development projects, attempt to win the hearts and minds of the populace while also restoring the economic strength and social cohesion of society. By building a relationship of trust with the local people, the senbu projects also had the effect of gaining their voluntary cooperation, including the provision of labor and human intelligence. Continuing to fight a different kind of battle after the shooting had stopped, senbu operatives were praised as "soldiers without weapons". Athletic events were also organized to improve relations with locals.
By restoring the fabric of society, the self-defense ability of rural settlements from bandit raids would be improved. This allowed citizens to better protect themselves from loss of life or property, and at the same time cut the bandits off from their rapport with the apathetic and poorly-educated Chinese populace, who had long since become accustomed to their presence, and their supply of food, "thus bringing about self-annihilation...".
Senbu operatives operated as forestry and logging supervisors to ensure Chinese guerillas could not hide in densely forested areas. Teams were also deployed to uncover and wipe out cells of Communists, arrest Soviet military spies, and infiltrate the Chinese Communist Party in order to make arrests and assassinations.
According to senbu progenitor Yaginuma Takeshi, " senbu ought to apply also to our Imperial Army. We must reform our own soldiers who behave cruelly toward the Chinese before reform the Chinese themselves".
Tōhikō, a gunka describing a senbu team's exploits against Chinese communists in the Khingan Mountains, was commissioned by the Kwantung Army. The lyrics were written by Yaginuma Takeshi and it was recorded by Fujiwara Yoshie.
