Hachisuka Matajūrō served as a bushō during the Sengoku period.
Matajūrō was adopted by the Taizō Temple in the village of Inagaki in Owari Province.
In 1566, Matajūrō served, along with his brother, Masakatsu, in the Siege of Sunomata Castle.
Matajūrō’s lineal heir was named Hachisuka Ieshige but adopted the name of Tagawa Tadaemon. After becoming a retainer of the Tokushima domain, he adopted the surname of Inagaki from the name of the village where the Taizō Temple was located.
