was a Japanese aristocrat, courtier, folk hero and samurai lord of the tenth century in the Heian period. He is famous for his military exploits and courage, and is regarded as the common ancestor of numerous clans, including the à Âshà « branch of the Fujiwara clan.
Hidesato served under Emperor Suzaku, and fought alongside Taira no Sadamori in 940 in suppressing the revolt of Taira no Masakado. His prayer for victory before this battle is commemorated in the Kachiya Festival. Hidesato was then appointed Chinjufu shà Âgun (Defender of the North) and Governor of Shimotsuke Province.
According to legend, he slew a giant centipede in à Âmi Province that plagued the Dragon Palace. He was also nicknamed Tawara Tà Âda.
Hidesato, also known by the moniker Tawara Tà Âda or Tawara no Tà Âta, is known in legend for his exploit of slaying the giant centipede (mukade) of Mount Mikami. Hidesato was recruited to this task by a giant dragon-snake, which was, in fact, a resident of the Ryà «gà «-jà  (Dragon Palace). Hidesato meets the Dragon King and is showered with rewards, which included an inexhaustible bale of rice (), from which he allegedly earned his nickname. A more rational explanation is that Tawara, also written differently as "ç°åÂÂ", represents either a surname or a place name.

One is the , a tachi of the or "tweezer" type. According to tradition, it was the sword obtained by Hidesato from the Ryà «gà «-jà Â, which later became an heirloom of the . After changing hands several times, it came into the shrine's possession in 1793. Although the Hidesato provenance is unverifiable, this sword is dated to be of the correct period.
The other alleged Hidesato sword at the museum is called "Centipede-cutter". Although its inscriptions claim it to be the work of the swordsmith from the 8th century, the sword has been dated to the 14th century.
There is also another "tweezer" type sword alleged to have belonged to Hidesato held in Chikubu Island, the .
Many samurai clans claim descent from Hidesato, including the Northern Fujiwara (à Âshà « branch of the Fujiwara clan). Some of the others are the , à Âtomo, , Iga, , , Yà «ki and Shimokà Âbe clans.
