Sassa Narimasa hailed from Hira Castle, now the site of Koutsu-ji Temple in Nishi-Ku, Nagoya City. At the age of 14, following his genpuku ceremony, he joined his father as a retainer of Oda Nobunaga. Serving under Nobunaga, Narimasa participated in campaigns against the Azai and Asakura clans. His valorous deeds during battles alongside Shibata Katsuie against the Uesugi clan earned him the lordship of Etchu Province (Toyama Prefecture).
Following Nobunaga's demise, Sassa Narimasa aligned himself with Tokugawa Ieyasu during the Battle of Komaki-Nagakute near Nagoya, where the outcome remained indecisive. Subsequently, under Ieyasu's command, Narimasa led 15,000 samurai in a siege of Suemori Castle in Noto Province, a stronghold held by his close friend Maeda Toshiie. Despite a valiant defense led by Commander Okumura Nagatomi, the castle was on the brink of surrender until Toshiie arrived with reinforcements, routing Narimasa's forces on the night of October 9, 1584.
The defeat compelled Narimasa to submit to Toyotomi Hideyoshi. Although initially forgiven, he faced challenges governing Hogo domain in Kumamoto, Kyushu, and failed to suppress a local peasant uprising. As a result, Hideyoshi ordered Narimasa to perform seppuku, which he dutifully carried out on July 7, 1588, at the age of 52.
