So Sadakuni
- Other Names: 国分寺殿 (Kokubunji dono)
- Japanese: 宗 貞国 (Sô Sadakuni)
Sô Sadakuni was the tenth head of the Sô clan. He held that position from 1468 until 1492. His time saw the relocation of the clan's territory from Saga (on the island of Kyushu) to Tsushima Fuchû (Izuhara), on the island of Tsushima,[1] as well as the end of the Sô family's status as vassals or retainers to the Shôni clan.
Sadakuni was the first member of a particular branch family - overseers of Toyosaki district - to become head of the mainline of the Sô house. From 1467 to 1471, he oversaw the construction of the Nakamura yakata, a new shugo mansion at Izuhara, on Tsushima. He launched efforts to regain clan territory in Chikuzen province and secured control over the port of Hakata for a time, but was soon afterwards defeated by the Ôuchi clan (based in western Honshu), and was forced to withdraw. After this, he separated his house from the Shôni clan, marking the end of the lord-vassal relationship between the Shôni and the Sô.
He was succeeded by his son Sô Kimori.
