Kandaten Shrine located in Koshu City in Yamanashi Prefecture is a shrine pertaining to the Takeda clan. Enshrined are Susanoo no Mikoto and other seven deities. It is said that the shrine was founded in 842 by the provincial governor, Fujiwara Iseo, by the Imperial order. When Sugawara no Michizane was enshrined together in 1004, the kanji “suga (菅)” was borrowed and the shrine came to be called Kandaten (菅田天). In the precinct is the statue of Zagyu (lying cow), which is believed to be the messenger of Sugawara no Michizane.
During the Warring States period (1493-1573), the shrine was protected by the Takeda clan as the god to guard the ominous direction of the provincial capital. The shrine is known for the possession of Kozakura Kawaodoshi Yoroi, which was one of the 8 armors handed down to the descendants of the Genji (the Minamoto clan). This armor was so strong that the one who wore it didn’t have to use a shield, so it was called “Tate-nashi-no-yoroi (the armor without a shield).” It was handed down to the heads of the Takeda clan, one of the rightful descendant family of the Seiwa Genji, as the family treasure together with Japan’s oldest Rising Sun flag.
