Koyu
Koyu lies on the eastern side of Hyūga, between wooded mountains and the Pacific coast. At Takanabe, the Akizuki family established a small domain after leaving their former lands in Chikuzen during Toyotomi Hideyoshi's conquest of Kyushu. Their descendants governed from the castle town through the Edo period. In 1778 the seventh lord, Akizuki Taneshige, founded the domain school Meirindō, making education part of the town's institutional life.
