Nantō Province

Nantō Province (南島州) is the southernmost province of Yamatai. It encompasses the entire Nantō island chain in a chain over 500 kilometres long. The Nantō islands are located southeast from Hasukuni, the southernmost main island of the Naichi archipelago, and stretch to Yeongseon.

The four largest islands in the Nantō island chain are Kintakeshima, Kita-Aoshima, Minami-Aoshima, and Daifujima. Kintake, the provincial capital and largest city in the province, is located on the southern part of Kintakeshima.

The indigenous people of Nantō Province are the Nantōjin people, who are closely related to the ethnic group.

History
Yamatai started colonising the northern Nantou islands since the 1600s to improve trade with Yeongseon and later to contain Yeongseon from expanding further northwards. In the 1790s, following a war of independence from Yeongseon that was supported by Yamatai, the King of Daebudo signed a treaty with Yamatai joining the Empire in return for becoming a Yamataian noble (too bad a few decades later the nobility became meaningless).

To the modern day, some Yeongseonin groups maintain the claim that Yamataian control over the islands is unlawful.

Daifujima
Also known as Daebudo (대부도), Daifujima has a large ethnic Yeongseonin population.
