Who was Taira no Masakado?
Taira no Masakado was a busho (military commander) and gōzoku (local powerful family) in Kanto during the mid-Heian period, the son of Taira no Yoshimasa of the Kanmu-Heishi (Taira clan originating from Emperor Kanmu), and the third son of Prince Takamochi (Taira no Takamochi), Emperor Kanmu's great-grandson. He is a historical figure who instigated a rebellion against the imperial court, serving as a turning point from the aristocratic society of the Heian period to the samurai society of the Kamakura period and beyond. While rebels are typically treated as villains, in the Eastern provinces where Masakado was involved, various legends remain, and numerous shrines and temples dedicated to Masakado still exist, honoring him as a local hero. His rebellion is known as "Taira no Masakado's Rebellion," and when combined with "Fujiwara no Sumitomo's Rebellion" that occurred in the Seto Inland Sea around the same time, it is collectively referred to as the "Jōhei-Tengyō Rebellion".
Taira no Masakado was born in Encho 3 (903) to Taira no Yoshimasa and the daughter of Agata no Inukai no Harue. He is said to have died on February 14, Tengyo 3 (March 25, 940), hit by a stray arrow in the "Battle of Kitayama" during the "Taira no Masakado Rebellion."
The historical background of Shimosa Province, Musashi Province, Hitachi Province, and other regions at that time included over 100 years of the Imperial Court's continued subjugation of the Emishi, subsequent Emishi rebellions, excessive taxes and labor burdens imposed by the Imperial Court on farmers and powerful families, and occurrences of famine and natural disasters.
It is believed that Masakado, amidst these circumstances, acted in support of the farmers and powerful families of Shimosa Province, Musashi Province, Hitachi Province, and other regions. Although Masakado became an enemy of the court, he was viewed as a hero in those areas, and numerous legends and related sites remain throughout Japan, centered in Chiba Prefecture and Ibaraki Prefecture, and including Tokyo, Saitama Prefecture, and Tochigi Prefecture.
The sites related to Masakado on this website are limited to Ibaraki Prefecture, but there are many battlefields and other related sites that have not yet been covered or published.
Overview of Taira no Masakado's Life
Taira no Masakado's Family Tree and Relationship Chart of Clan Disputes

The above is Taira no Masakado's family tree and the relationship chart of clan disputes. These family disputes developed into the "Taira no Masakado Rebellion." The clan dispute began as a conflict over land inherited from his parents, which had been taken over by Kunika, after Masakado returned from Kyoto. It then escalated into armed conflict with the addition of the dispute between Taira no Maki and Minamoto no Mamoru, who were relatives of both sides.
The main figures are explained below, but some are legends, and while it is true that there are places associated with them, the content and explanations of the legends may contain contradictions or be speculative.
- (1)Prince Takamochi
- He was Taira no Masakado's great-grandfather (great-grandson of Emperor Kanmu). In the first year of Kanpyō (889), he was granted the 'Taira' surname and descended from imperial ranks, becoming the ancestor of the Kanmu-Heishi clan. He was appointed Kazusa-no-suke and moved to the eastern provinces, where his descendants settled as the Bandō-Heishi clan.
- (2)Taira no Kunika
- He was Taira no Masakado's uncle and Prince Takamochi's eldest son. He served as Hitachi no Daijō and Chinjufu Shogun, and was a central figure of the Kanmu-Heishi clan. Due to an inter-clan dispute with Taira no Masakado (involving the inheritance of Masakado's father, Taira no Yoshimasa, and women-related issues), he was attacked by Masakado in the 'Battle of Nomoto' in Jōhei 5 (935) and died in defeat at Ishida-kan in Hitachi Province (present-day Chikusei City, Ibaraki Prefecture). This is considered one of the direct triggers of the 'Taira no Masakado Rebellion.' Kunika's son, Taira no Sadamori, became a central figure in the pursuit and subjugation of Masakado.
- (3)Taira no Yoshikane
- He was Taira no Masakado's uncle and Prince Takamochi's second son. He served as Kazusa-no-suke and Chinjufu Shogun. After his elder brother Kunika was killed by Masakado, he repeatedly fought against Masakado, along with his younger brother Yoshimasa and Kunika's son Sadamori. He was also Masakado's father-in-law (his wife's father), and it is said that his daughter eloping with Masakado was one reason for the escalation of the conflict. He died of illness in Tenkei 2 (939).
- (4)Taira no Yoshimochi
- He was **Taira no Masakado's father**, and is said to be Prince Takamochi's third son, though there are various theories. He held the official position of Chinjufu Shogun until his death. There are theories that he is the same person as 'Yoshimasa' and theories that he is a different person.
- (5)Taira no Yoshimasa
- He was Taira no Masakado's uncle and a son of Prince Takamochi. He was based in Mizumori, Hitachi Province (present-day Mizumori, Tsukuba City, Ibaraki Prefecture). In the conflict with Taira no Masakado, he initially sided with the Minamoto no Mamoru family, who opposed Masakado, creating a factor that intensified the conflict with Masakado. He fought battles against Masakado along with Yoshikane and Sadamori.
- (6)Taira no Yoshifumi
- He was Taira no Masakado's uncle and a son of Prince Takamochi. He was commonly known as 'Muraoka Gorō' and was known as a person of excellent martial prowess. In later historical documents such as the 'Genpei Tōjōroku,' he is said to have become Masakado's adopted son and sided with Masakado in the conflict between Masakado and his uncles. However, his historical involvement seems to be largely unclear. He is considered the ancestor of the Eight Taira Clans of Bandō and the ancestor of later samurai groups (such as the Chiba clan and Kazusa clan).
- (7)Taira no Sadamori
- Taira no Sadamori was the eldest son of Taira no Kunika, Masakado's uncle, making him Masakado's cousin. After Masakado killed his uncle Kunika, Sadamori, upon learning the circumstances, initially showed an attitude of seeking reconciliation with Masakado. However, driven by a strong desire to avenge his father, he ultimately became a central figure in the subjugation of Masakado. By cooperating with Fujiwara no Hidesato and defeating Masakado, the Taira no Masakado Rebellion concluded. The 'Shōmonki' (Tale of Masakado) is a war chronicle by an unknown author, but in 'Taira no Masakado: His Truth' (by Hiroshi Shiono), there is a theory, based on evidence, that it was originally an outline written by Taira no Sadamori and rewritten by a Kyoto aristocrat.
- (8)Taira no Maki
- Taira no Maki was a local powerful family (shōen lord: lord and administrator of Ōkunitama Shrine) in Niihari District, Hitachi Province. Although bearing the Taira surname, he is considered to be of a different lineage than the Kanmu-Heishi of the Prince Takamochi line. He frequently disputed territories with the neighboring Minamoto no Mamoru. By asking Masakado to mediate this dispute, he created the catalyst for Masakado's conflict with Minamoto no Mamoru. From descriptions in the 'Shōmonki' and other sources, Taira no Maki is thought to have cooperated with Masakado as a 'strong ally' in Masakado's early actions. Kimi no Gozen is Taira no Maki's daughter.
- (9)Minamoto no Mamoru
- Minamoto no Mamoru was a powerful local magnate in Hitachi Province, holding the official position of Hitachi no Daijō, and was based in the Akahama region, around present-day Chikusei City and Sakuragawa City. He actively formed marital ties with members of the Taira clan to expand his influence. Indeed, he married off three of his daughters to figures such as Taira no Kunika, Taira no Yoshikane, and Taira no Yoshimasa, who were Masakado's uncles. While Masakado was on his way to Taira no Maki's residence, he was ambushed and attacked by Minamoto no Mamoru's three sons, 'Tasuku, Takashi, and Shigeru.' He managed to defeat them, utilizing the favorable winds. This is known as the 'Battle of Nomoto.'
- (10)Taira no Yoshiko
- Taira no Yoshiko was the daughter of Taira no Yoshikane, Masakado's uncle, making her his cousin. The 'Shōmonki' records that Yoshikane and Masakado had a 'father-in-law and son-in-law relationship,' which is interpreted as Masakado having taken Yoshikane's daughter as his wife. This marriage was not peaceful; there is a description that Masakado forcibly took the daughter against Yoshikane's wishes. Separately, 'Bando no Fūunji: Taira no Masakado' states that they met at a 'kagai' (poetry gathering) on Mount Tsukuba, where Masakado learned she was Yoshikane's daughter. They made a pledge before he left for training in Kyoto, and when he returned, they eloped because of opposition. This is thought to have been one cause of the conflict between Masakado and Yoshikane, but there appears to be no clear description of Yoshiko's fate during Masakado's rebellion.
- (11)Taira no Yoshiko
- Taira no Yoshiko is said to be the daughter of Taira no Yoshikane, Masakado's uncle. In other words, she was his cousin. The 'Shōmonki' records that Yoshikane and Masakado had a 'father-in-law and son-in-law relationship,' which is interpreted as Masakado having taken Yoshikane's daughter as his wife. This marriage was not peaceful; there is a description that Masakado forcibly took the daughter against Yoshikane's wishes. Separately, 'Bando no Fūunji: Taira no Masakado' states that they met at a 'kagai' (poetry gathering) on Mount Tsukuba, where Masakado learned she was Yoshikane's daughter. They made a pledge before he left for training in Kyoto, and when he returned, they eloped because of opposition. This is thought to have been one cause of the conflict between Masakado and Yoshikane, but there appears to be no clear description of Yoshiko's fate during Masakado's rebellion.
- (12)Kimi no Gozen
- A legend remains in Sakuragawa City, Ibaraki Prefecture, and other areas, stating that Kimi no Onmae was the daughter of Taira no Maki. There is also a legend describing the encounter between Kimi no Onmae and Masakado at the Tsukuba Mountain Kagai (song-exchange gathering). Furthermore, this legend claims that the wife slain in the "Battle of Horikoshi-watashi," as recorded in the Shomonki, was in fact Kimi no Onmae. The story that "Kisaki Jinja" (Empress Shrine) was built to mourn her is also written on the explanatory board of Kisaki Jinja.
- (13) Kikyō no Mae
- Kikyō no Mae is a legendary woman said to be Taira no Masakado's concubine. There are various legends regarding her origin and ultimate fate, with many theories existing depending on the region. As for her background, one theory states that she was a shirabyōshi (female dancer) from Kyoto who caught Masakado's eye, while another claims she was Fujiwara no Hidesato's younger sister, sent to Masakado as a servant. Common points in the main legends include that she was deeply cherished by Masakado, that she secretly collaborated with Fujiwara no Hidesato, and as a result, Masakado was defeated and she herself met a tragic end.
