Monument of the Death of Inspector Koyama and Goto, Police Officer Baratsu of Karenkou Prefecture

The Monument of the Death of Inspector Koyama and Goto, and Police Officer Baratsu of Karenkou Prefecture is located on the mountainside by the Batongguan Traversing Historic Trail, about 50 meters north from Ying Bridge (No. 7 Bridge). There were originally two wooden pillars commemorating the two inspectors who were killed in an ambush on April 11, 1922. The indigenous police officer who died in the same incident was not listed. Therefore, when the pillars were replaced with a reinforced concrete obelisk in the 1930s,  the names of the three victims were placed side by side.
