Coming down the small hill on which lies Oh Shrine there is a second small shrine, Goh Shrine, which enshrines Wake no Kiyomaro, a government official in the 7th Century.
He is connected to the famous Dokyo Incident. Usa Shrine, now Usa Hachimangu, rose to power to a certain extent due to its oracles. One oracle in 769 suggested that the monk Dokyo should be the next emperor. Dokyo is often likened to Rasputin. He was very much in favor with Empress Koken after he cured her of an illness in 761. Wake no Kiyomaro was sent to Usa to check the oracle and came back with a second oracle refuting the first by saying that only descendants of Amaterasu, and not commoners could become Emperor.
Under Dokyos influence the Empress banished Kiyomaro, but after her death he was recalled and promoted. He undertook an investigation and found that more oracles were deemed fraudulent and the head priest of Usa was removed.
He is also credited with convincing Emperor Kammu to abandon Nagaoka and move to what is now known as Kyoto.
