Haramiishi Motoshige served as a bushō during the Azuchi-Momoyama and early Edo periods.
The Haramiishi were an illegitimate branch of the Hara, a branch of the Kudō clan of the Fujiwara-Nanke. Motoshige’s ancestor, Hara Tadataka resided in the village of Haramiishi in the Harada manor of Tōtōmi Province and adopted the surname of Haramiishi.
Motoshige was born as the designated heir of Haramiishi Motoyasu.
Initially, Motoshige joined his father to serve the Imagawa clan. After the Imagawa were extinguished, he served the Kai-Takeda clan. After the demise of the Kai-Takeda, he became a rōnin, or wandering samurai.
In 1590, during the Conquest of Odawara by Toyotomi Hideyoshi, Motoshige joined Inui Masanobu, who was also a rōnin and former retainer of the Takeda, to fight valiantly on behalf of the Toyotomi clan. That same year, owing to his contributions, he was engaged in service by Yamauchi Kazutoyo and received a fief of 200 koku. He received a title equivalent to Junior Sixth Rank.
After the Battle of Sekigahara, when Kazutoyo was transferred to Tosa Province, Motoshige was granted a fief of 450 koku, and, in 1619, he was ordered by the lord of the domain, Yamauchi Tadayoshi, to serve as the mentor for Yamauchi Tadatoyo. He then received an increase of 200 koku to his fief.
Motoshige died in 1632. He was succeeded by his adopted son, Kuranosuke Masamoto (the second son of Kibe Tōbei – a chief retainer of the Tosa domain and father of Haramiishi Motomasa, a bushi in the early Edo period).
