| The text includes the story of 12th century samurai [[Minamoto no Tametomo]] being the father of Shunten, and thus progenitor of the Ryukyuan royal lineage. This served to link the Ryukyuan royal family to the Japanese imperial line, via Tametomo, the [[Seiwa Genji]] line of the [[Minamoto clan]], and [[Emperor Seiwa]], and also to the [[Tokugawa clan]] (who also claimed descent from the Seiwa Genji) in tune with the political leanings of the time, as Ryûkyû had just been subjugated by Satsuma some 40 years earlier, and Shô Shôken was a member of a faction at court advocating a more pro-Japanese stance. Scholars today consider this story and link to the Minamoto a falsehood, but the tale was believed quite widely at the time, appearing in numerous Japanese works on Ryukyuan history, including [[Arai Hakuseki]]'s ''[[Nantoshi|Nantôshi]]''. The ''Chûzan seikan'' is among the earliest works in which this story appears, but the actual origin of the story is unclear. | | The text includes the story of 12th century samurai [[Minamoto no Tametomo]] being the father of Shunten, and thus progenitor of the Ryukyuan royal lineage.
