Kamata Masatoshi served as a bushō during the Sengoku and Azuchi-Momoyama periods.  He was a retainer of the Shimazu clan of Satsuma Province.

Masatoshi served three generations of lords, namely, Shimazu Tadayoshi, Shimazu Takahisa, and Shimazu Yoshihisa.  He served as the lord of the manor in Umakoshi in Satsuma Province, in Mitsuyama in Hyūga Province, and in Chōsa and Ushine in Ōsumi Province.

Masatoshi achieved numerous military exploits including in an attack against Gamō Norikiyo of northern Satsuma in 1557 and Hishikari Takaaki at Umakoshi Castle in Satsuma in 1568.  In particular, in regard to the attack on Umakoshi Castle, Shimazu Tadayoshi commended Masatoshi for his contributions and said that the Shimazu family would never forget his distinguished service.

On 5/4 of Genki 3 (1572), after the outbreak of the Battle of Kizakibaru, Masatoshi accompanied Shimazu Yoshihiro to lead 150 soldiers on a deployment.  These forces proceeded to attack soldiers from the Hyūga-Itō clan found resting alongside the Ikejima River.  Masatoshi then led 60 soldiers provided by Yoshihiro to go around behind the Itō army and, together with forces led by Yoshihiro and by Godai Tomoyoshi, repelled an Itō army of over 3,000 men.

In 1578, after the Shimazu defeated the Ōtomo at the Battle of Mimikawa, the Jō and Nawa clans, gōzoku, or wealthy families, in Higo Province fostered friendly relations with the Shimazu clan.  In suppport of these clans, Masatoshi led a battalion to Higo.  In 1580, Masatoshi, along with Niiro Tadamoto, invaded the territory of the Aso clan in Higo, attacking and killing Nakamura Korefuyu, the lord of Yazaki Castle in the Uto District.

There are two theories regarding the date of his death, either 7/8 of Tenshō 11 (1583) or 7/10 of Tenshō 15 (1587).  He was buried at the 喜翁 Temple in Futagawa on Mount Nozomi in Ushine in the Aira District of Satsuma.
