Buzen Nagano

The Buzen Nagano were local lords based at Nagano Castle in northern Kyushu. From Japan's Northern and Southern Courts period, they held influence in the Kiku, Tagawa and Miyako districts of Buzen.

The family came under the Mōri in 1558 and the Ōtomo in 1565. Driven from Kiku to Umagatake Castle, they regained independence after the Ōtomo defeat at Mimikawa in 1578, in alliance with Akizuki Tanezane and Takahashi Mototane. They submitted during Toyotomi Hideyoshi's Kyushu campaign; after 1587, members served other lords.
