This is the castle of Fujiwara no Chikata, who appears in the Taiheiki, or Records of Great Peace. In the Heian Period, noble family Fujiwara no Chikata started war with the imperial court, used the yonki (four devils: gold devil, wind devil, water devil, stealth devil) to distress the imperial armies. The waka poem of Kinotomo, who had come to put down Fujiwara no Chikata, said “All things, whether grass or tree, are ruled by the Emperor, and not even a devil can turn his back to the Emperor and live in this land” to disperse the four devils and Fujiwara no Chikata was defeated. The four devils are said to have been the original archetype for ninja. The Chikata deity was built in 1760, and commemorates Fujiwara no Chikata and Wakamiya deities.
