Koma Shrine is located in Niihori, Hidaka City, Saitama Prefecture. The enshrined deities are Koma no Koshiki Jakko, Sarutahiko no Mikoto and Takenouchi no Sukune (a legendary statesman). The shrine was founded in 716 by an emissary from Goguryeo, Koma no Koshiki Jakko, as the head shrine to guard the Koma district (present-day Hidaka City). It was originally named Shirahige Myojin and is the headquarters of all the 55 Shirahige and Shirahige Myojin shrines in the Musashi province (present-day Saitama Prefecture), from which it is also called Koma Soja Shrine (the head shrine).
In the precinct are a lot of cultural properties including the Old Koma Family Residence. Since the Meiji period, a lot of people, who had visited this shrine to offer a prayer, became powerful politicians including prime ministers, the shrine has been worshipped as Shusse (career success) Myojin. Koma Shrine is also famous for cherry blossoms in spring and chrysanthemum flowers in fall.
