He is the main deity enshrined at Hachiman shrines throughout Japan, and Onnazuka Shrine also has a history of being called “Hachiman Shrine.”

History and Origins of Onnazuka Shrine
Founding Date and Former Name
The founding date of Onnazuka Shrine is unknown, but it was formerly called Hachiman Shrine and was revered as the tutelary deity of Onnazuka Village and Misono Village. It is believed to have already functioned as a local guardian shrine during the Edo period.
The original location was Onnazuka Village, No. 429, near the current east exit of Kamata Station. This former shrine site is located in the bustling area around Kamata Station, where the Keihin-Tohoku Line runs, suggesting that it was the center of the village before the railway was built in the Meiji era.
Relocation and Renaming in the Meiji Era
The most important turning point in the history of Onnazuka Shrine was the construction of the railway in the Meiji era.
1872 (Meiji 5): The construction of Japan’s first railway, the Shinbashi-Yokohama line (later the Tokaido Main Line and Keihin-Tohoku Line), was decided, and the grounds of the Hachiman Shrine were acquired as railway land.
1888 (Meiji 21): The Hachiman Shrine was relocated to its current location and simultaneously renamed Onnazuka Shrine. This renaming originates from the ancient burial mound called “Onnazuka” that existed at the relocation site. With the relocation, it became the guardian shrine only for Onnazuka Village.
This relocation is a valuable example demonstrating the impact that Japan’s modernization and the development of the railway network had on local religious beliefs. The current Tokyo railway network was formed through the relocation and reorganization of many shrines and temples.
The Legend of the Onnazuka Tumulus and Shōshō no Tsubone
Within the grounds of Onnazuka Shrine lies the Onnazuka Tumulus, from which the shrine derives its name. This tumulus holds a tragic history from the Nanboku-chō period.
The Story of Nitta Yoshioki and Shōshō no Tsubone
Nitta Yoshioki (1331-1358) was the second son of Nitta Yoshisada, who overthrew the Kamakura Shogunate, and a warrior of the Southern Court. In Shōhei 13/Enbun 3 (1358), Yoshioki was murdered at the Yaguchi ferry crossing in Musashi Province (near present-day Yaguchi, Ōta Ward) due to a plot by Ashikaga Takauji.
It is said that Shōshō no Tsubone, a lady-in-waiting who served Yoshioki, also lost her life in loyalty to her lord. The villagers, pitying the young and tragic death of Shosho-no-Tsubone, are said to have built a mound in this place to enshrine her.
This legend is a valuable historical legacy that conveys the Japanese spiritual culture that values the bond between lord and vassal and loyalty. Nitta Yoshioki himself is enshrined at Nitta Shrine (Yaguchi, Ota Ward) near the Yaguchi ferry crossing, and there is a deep historical connection between this shrine and Onnazuka Shrine.
Archaeological Aspects of Onnazuka Kofun
Archaeologically, Onnazuka Kofun is estimated to be a circular burial mound constructed during the Kofun period (around the 6th-7th centuries). While the legend of Shosho-no-Tsubone was added later, it is certain that a mound existed in this area since ancient times and was some kind of object of worship.
Currently, Onnazuka Kofun is preserved within the shrine grounds and is positioned as an important historical site that conveys the history of Ota Ward.

History of Ota Ward and Onnazuka Shrine
Origins of Ota Ward
Ota Ward was formed in 1947 (Showa 22) through the merger of Omori Ward and Kamata Ward. The Nishikamata district, where Onnazuka Shrine is located, was formerly part of Kamata Ward and has transformed from an agricultural area to an industrial area and then to a residential area.
Railways and Regional Development
The construction of the railway in 1872 (Meiji 5) not only led to the relocation of Onnazuka Shrine but also served as a catalyst for the development of the entire Kamata area. The area around Kamata Station developed into an important transportation hub in southern Tokyo, and today it is a diverse town with a mix of commercial, residential, and industrial areas.
The history of Onnazuka Shrine can truly be considered a living witness to the modernization of Tokyo and the transformation of the region.
Summary: A Recommendation to Visit Onnazuka Shrine
Onnazuka Shrine, located in the urban area of Nishikamata, Ota Ward, Tokyo, is a valuable shrine that conveys two historical events: the tragedy of the Nanboku-cho period and the modernization of the Meiji era.
Its excellent accessibility (a 5-minute walk from Hasunuma Station), the Onnazuka Kofun (ancient burial mound) remaining on the shrine grounds, and the story of Nitta Yoshioki and Shosho-no-Tsubone leave a deep impression on visitors. Since the Goshuin (temple/shrine stamp) is given at Kamata Hachiman Shrine, planning a pilgrimage route that includes both shrines will allow you to gain a deeper understanding of Ota Ward’s history and faith.
Nestled in a quiet residential area, Onnazuka Shrine offers a place to pray while reflecting on history. Be sure to visit it when sightseeing in Tokyo or visiting shrines.
