After war had officaly ended in August 15th, a leaflet was droped by locals, but they thought it was a propaganda trick made by Allies, so they continued to raid locals, attacking the enemy which no longer existed. After that, leaflets were dropped from plane with surrender orders.
In 1949, one of his soldiers, Yuichi Akatsu escaped from the group and surrended to Philiphine soldiers in 1950.
In 1952, they dropped leaflets again from plane but this time, there were pictures of their families. But again, they thought it was a trick. In fact, this events increased their paranoia.
They were shooting locals because they were in civilian clothing which led them to believe they were disguised soldiers of Allies.
