Shujukoku

Shujukoku (侏儒国, しゅじゅこく) is a country of dwarves thought to be located south of Yamataikoku, which appears in Ancient China's Book of the Later Han and Records of the Three Kingdoms.

The Shanhai Jing, a document that precedes the Wajinden, mentions an island called Shojin-koku [ja] in the eastern sea.

The same book also mentions other dwarfs such as "(焦僥)", "(周饒)", and "(菌人)" living in the east and south.

[citation needed]This is the reason why Tanegashima Island is located in the south of Kyushu.

Tanegashima is located about 4,000 ri south of northern Kyushu, which is about 4,000 ri in the shortest sense of the word, so some Yamatai Kyushu Theorists have compared the country to Tanegashima.
