Given a dramatic legendary narrative in the official histories, the conflict allowed Taikyū to take control of the two gusuku (castles) and monopolize trade connections with Joseon.

His successor, Shō Toku, was officially recorded as his son, but may have been an unrelated leader (possibly a wakō pirate) who overthrew Taikyū.

The Chūzan Seikan (中山世鑑, Reflections on Chūzan), a 1650 official history of the Ryukyu Kingdom, describes Taikyū as the son of King Shō Kinpuku; however, Kinpuku's birth date is listed in the official histories as 1398, which would imply he fathered Taikyū at the unrealistically young age of eleven or twelve.

Prior to his rise to the kingship of Chūzan, the official histories refer to Taikyū as "Prince Goeku", an anachronistic title which developed in later periods.

The 16th-century Omoro Sōshi (おもろさうし), a compilation of Okinawan songs and poems, describes him not as a blood relative of Hashi, but as the son of a ruler of Goeku.

The most of important of these, the Bridge of Nations Bell (Bankoku shinryō no kane), was cast by a Japanese metalworker and placed on display in front of the rebuilt palace.

It praises his "activation of the Three Jewels" and names him the savior of "the masses of the Three Worlds", possibly in emulation of the Buddhist conception of the chakravartin, a benevolent universal ruler.

[9][11] Keiin's inscription also states that Taikyū gathered together "wen and wu" and the "excellence of Korea", indicating influence from Chinese and Korean culture.

The official histories describe Amawari, the aji (lord) of Katsuren, lying to Taikyū that Gosamaru of Nakagusuku had been scheming against his rule.

As the official histories portray Okinawa as having been a unified kingdom for several centuries by the time of Taikyū, wars with neighboring polities and aji may have been reinterpreted as rebellions in later retellings.

[15] Taikyū's territory of firm control was likely initially limited to the region around Shuri and Naha, alongside Goeku in central Okinawa.

Due to the chaotic beginnings of his reign, Smits theorizes that he may have been an unrelated wakō pirate leader who took the throne in order to monopolize Chūzan's trade connections.
