the Imperial court in Kyōto recognized his leadership of Eastern Japan following the decline of the Taira. The two good things having happened Yoritomo proceeded to build and dedicate a shrine utilising the Kanjō process to enshrine Sugawara, the kami of the Dazaifu Tenmangū. The gyūishi was installed as the shintai. The site chosen by Yoritomo was to the east of the shrine's current location, but during the Kan'ei Period (1624-1645) it was moved to its current location following the formation of the Mito Domain.

Description

10 min walk from Korakuen, Kasuga, and Iidabashi Stations. There is an interesting story about the in-ground Ōta Jinja which was featured in the Shinpen Tōkyō Meisho-zue (新撰東京名所図絵,  "New Illustrated guide to Famous Tōkyō Sights") a pictorial magazine published from 1890 to 1914. It was based on the reminiscences of old people living in the Koishikawa area.

<The original kami of the Ota Jinja was Koroyama-ten-nyo (黒闇天女), the kami of poverty, and Benzaiten's older sister. During the Edo Period there was a low-ranking feudal retainer living in the area. Owing to his status his life was basic, but not particularly unhappy. One night Koroyama-ten-nyo appeared to the retainer in a dream and told him that she had also been living in the house, which for her had been quite comfortable. However, the time had come for her to move on, but as an expression of her gratitude she wanted to give him a chance of a better life. To realize this, he would have to make offerings of red rice (赤飯) and deep-fried slices of tofu (油揚げ)  to her three times a month. He immediately began to do so and soon became quite rich. He had a statue of Koroyama-ten-nyo made and prayed to it daily. On his death his descendants, fearful that their lives would revert to poverty, explained the situation to the priests at Kitano Jinja and as a result the statue was enshrined there. A nearby master carpenter later heard of this, and prayed to the goddess for success in winning a contract from the Bakufu, offering to build a new shrine for her if he succeeded. He did, and built a jinja, now known as Ota Jinja, enshrining Koroyama-ten-nyo. Thereafter she became known as the Kami of Happiness. The shrine's home page tells us that Ota Jinja and Takagi Jinja between them enshrine the husband and wife team of  Ame-no-uzume-mikoto, the Kami of Entertainers, and Saruta-hiko-mikoto, the Kami of Roads, as well as Uka-no-mitama mikoto.
