, read variously as Tarumoi and Tarumë, was a local ruler of Okinawa Island, who was given the title of King of Sannan. He first contacted the Chinese emperor in 1415, claiming himself to be an heir to King à Âà Âso, without clearly specifying his blood relationship with the former king. He claimed that à Âà Âso was killed by his elder brother Tabuchi, who had in turn been killed by local chiefs, in favor of Crown Prince Taromai. This report was highly unusual because Okinawans routinely deceived the Chinese into thinking that the throne was normally succeeded from the father to the son. Historian Dana Masayuki raises the possibility that it was a cover story for Taromai's illegitimate seizure of power. His last contact was of 1429. The Chinese records suggest that the Chinese had no information on when and how the king disappeared. Because the King of Chà «zan continued tributary missions, the Chinese later speculated that the Kings of Sannan and Sanhoku had been removed by the King of Chà «zan.
Taromai was quite unusual for Okinawan rulers in Chinese records, in that the name appears to represent a genuine Okinawan given name: Taru-mi. Tarà « was a common given name while -mi (<*omopi) was a suffix commonly used by ruling elites.
Historian Wada Hisanori notes that the Rekidai Hà Âan contains diplomatic documents supposedly sent by Taromai, King of Sannan. Wada speculates that Shà  Hashi, the unifier of Okinawa Island, had already kept Sannan under his control. According to his hypothesis, Taromai was the eldest son of Shà  Hashi while à Âà Âso was either a pseudonym of Shà  Hashi or his puppet ruler. Shà  Hashi gave southern Okinawa to the first son while the rule of northern Okinawa was left to his second son Shà  Chà «.
Okinawans later identified the King of Sannan as the Aji (local ruler) of à Âzato but had no information on how many rulers had assumed the title. Because Taromai was the last known King of Sannan, a logical consequence was that the Aji of à Âzato who was annihilated by Shà  Hashi was Taromai. However, neither the Chà «zan Seikan (1650) nor Sai Taku's edition of the Chà «zan Seifu (1701) identified the Aji of à Âzato in question as such.
According to the Chà «zan Seikan (1650), the unnamed King of Sannan lost popular support. Shà  Hashi, then the Aji of Sashiki, overthrew the King of Sannan and became King of Sannan himself. The King of Sannan then replaced Bunei as King of Chà «zan in 1421. Shà  Hashi finally overthrew the King of Sanhoku in 1422, unifying Okinawa Island. The Chà «zan Seikan did not date Shà  Hashi's overthrow of the King of Sannan. Sai Taku's edition of the Chà «zan Seifu (1701) generally followed the Chà «zan Seikan.
Sai On's edition of Chà «zan Seifu (1725) is drastically different from these two books. Having access to Chinese diplomatic records, Sai On added the records of tributary missions sent under the name of King Taromai. The last king was now identified as Taromai. More importantly, Sai On changed the date of the King of Sannan's downfall to 1429, postdating Shà  Hashi's conquest of the King of Chà «zan in 1406 and that of the King of Sanhoku in 1416. Sai On naïvely inferred that the King of Sannan was removed immediately after the last tributary mission of 1429.
Sai On's attempt to resolve contradictions between the traditional Okinawan narrative and Chinese sources was a source of another inconsistency. The Chà «zan Seikan (1650) suggested that the Aji of Shimasoe-à Âzato had been the King of Sannan. Because Sashiki, Shà  Hashi's stronghold, neighbored Shimasoe-à Âzato, his conquest must have started with the overthrow of the Aji of Shimasoe-à Âzato. Even though Sai On put Shà  Hashi's conquest of the King of Sannan at the final phase of his conquest, he somehow kept the episode of Shà  Hashi's takeover of the Aji of à Âzato in his early years. To resolve the new contradiction, Sai On had to re-identify the Aji of à Âzato in question as the Aji of Shimasoe-à Âzato while the King of Sannan, annihilated supposedly much later, was identified as the Aji of Shimajiri-à Âzato.
