Attack on Kishu - Kishuzeme

...The Negoro and Saika groups are also famous as powerful fighting groups that were among the first to adopt firearms. Thus, in the Sengoku period in Kii Province, due in part to the division of the Hatakeyama clan, no powerful individual capable of leading the province emerged, and old and new regional groups continued to make alliances and fight each other repeatedly. The unification of the country had to wait until Oda Nobunaga and Toyotomi Hideyoshi attacked Kii Province. [Yasunori Koyama]
[Early Modern Period]
