後陽成天皇
In 1588 it is recorded that Hayashi Tosa-no-kami is promoted to the position where he receives direct orders from Hideyoshi on strategies in Kyūshū. The reason Hideyoshi chose Narinaga for this was because he held extensive knowledge of Kyūshū where his ancestors from the Kikuchi clan had ruled. This year Hideyoshi bestowed the Toyotomi uji (豊臣朝臣, "Toyotomi-no-asomi", courtier of Toyotomi) upon his closest followers including Narinaga. In July, 1588 of the same year Narinaga is given the new title of "Hizen-no-kami" (肥前守) in accordance with the Junior Fifth Rank, Junior Grade (Ju go-i-no-ge, 従五位下). The same month, Emperor Go-Yōzei visited Toyotomi Hideyoshi's mansion and the Sword hunt Edict was declared. Three years later in 1591 Mōri Terumoto began the construction of Hiroshima Castle.
