In 1582, after Oda Nobunaga's death at Honnō-ji, at the Kiyosu meeting, Narimasa took the side of Shibata, but he could not participate in the battle of Shizugatake in 1583, since he could not leave Etchu where he was preparing for the attack of the Uesugi army at Matsukura Castle (Toyama Prefecture). After the death of Katsuie, Narimasa joined Tokugawa Ieyasu.
In 1584, during the battle of Komaki Nagakute, he and the Tokugawa alliance unsuccessfully challenged the Toyotomi force under Maeda Toshiie at the Siege of Suemori.
In 1585, he was defeated by Toyotomi Hideyoshi at Siege of Toyama, and later Narimasa submitted to Hideyoshi and his life was spared.
In 1588, however, due to difficulties in suppressing a Higo Province local revolt, he committed suicide (seppuku) by Hideyoshi's instruction.1 The insurrection stemmed from survey of his province, which resulted in a change in the distance in which farmers transported their tax rice from 3 ri to 8 ri.6
Later, after Higo Province was confiscated from Sassa Narimasa, land in Higo (roughly half of the province) and Kumamoto Castle was granted to Kato Kiyomasa.
