Hiratsuka Shrine
平塚神社Hiratsuka Shrine is said to have been founded in the late Heian period. Prince Hachiman Taro Minamoto Yoshiie visited this area with his brother on his triumphal march to conquer Oshu, and was given a piece of armor by the lord Toyoshima Taro Chikayoshi. Konyoshi buried the armor he received in a clean ground and built a mound to protect his castle. The mound was called an armor mound, and because it had no height, it was also called a flat mound. In addition, Kinyoshi built a shrine and enshrined the three brothers Yoshiie, Yoshitsuna, and Yoshimitsu as Hiratsuka Sansho Daimyojin, and wished for the prosperity of the family.
During the Tokugawa period, Yamakawa Castle official Sadahisa, who was a blind man in Hiratsuka-go, prayed to Hiratsuka Myojin for a career and went to Edo, where he obtained a high position as an inspector and became a close associate of the shogun Tokugawa Iemitsu. Later, when Iemitsu fell ill, Yamakawa prayed to Hiratsuka Myojin for Iemitsu's healing. The shogun's illness was quickly cured, and Yamakawa Castle, grateful to the gods, restored the Hiratsuka Akira Shrine. Iemitsu himself donated a fifty-stone red seal land to Hiratsuka Myojin and often visited it for pilgrimage.
