Yamazaki Naganori served as a bushō from the Sengoku to early Edo periods.
There are several theories concerning the origins of the Yamazaki clan, including as descendants of the Fujiwara clan having taken an appointment to serve as officials of the central authorities in Echizen Province or, based on stories of the Yamazaki clan, as descendants of the Akamatsu branch of the Murakami-Genji.
Naganori was born in 1552. His childhood name was Koshichirō and he had the common name of Shōbei. Initially, he served as a retainer of Asakura Yoshikage of Echizen Province. This likely owed to his familial relation with Yamazaki Yoshiie, a veteran retainer of Yoshikage. Naganori’s father is said to have been Yoshiie’s younger brother, Yamazaki Yoshinobu, but this is not certain. In 1573, the Oda army burned down the base of the Asakura clan in Ichijōdani and the clan was decimated by Oda Nobunaga. Afterwards, Naganori served Akechi Mitsuhide, a senior retainer of Nobunaga. On 6/2 of Tenshō 10 (1582), Naganori participated in a coup d’état against Nobunaga known as the Honnō Temple Incident and the Battle of Yamazaki occurring in its wake.
Following the death of Mitsuhide at the Battle of Yamazaki, Naganori served Shibata Katsuie in Echizen Province. In 1583, at the Battle of Shizugatake, he fought under Sakuma Yasumasa, a retainer of Katsuie. Upon the death of Katsuie, Naganori served Maeda Toshiie and then Maeda Toshinaga. In 1600, at the Battle of Sekigahara, Naganori killed Yamaguchi Munenaga and Yamaguchi Nagahiro (father and son) of the Daishōji Castle in Kaga Province. After the war, Toshinaga recognized Naganori for his contributions with a grant of 14,000 koku. Naganori also joined, in 1614, the Winter Campaign of the Siege of Ōsaka and, in 1615, the Summer Campaign of the Siege of Ōsaka.
Naganori’s son, Yamazaki Nagasato, was married to the daughter of a woman named Gōhime who in turn was the daughter of Maeda Toshiie. Nagasato’s wife had been adopted by Maeda Toshinaga and was named Rishōin (Sadahime or Sahohime).
In 1620, Naganori died at the age of sixty-nine. He was known as skilled in the art of the spear.
Assorted families of the Yamazaki have continued to the present, including the Yamazaki-Shōbei family, retainers of the Kaga domain from the main branch of the Yamazaki which produced Yamazaki Norihisa, a chief retainer of the Kaga domain at the end of the Edo period, in addition to the Yamazaki Gonsuke cadet family serving as retainers of the Daishōji domain and a further branch of the Yamazaki Gonsuke family known as the Yamazaki-Tosho family.
