Tamagusuku Chokun was the creator of the performance art Kumi-odori, the national theater of the Ryukyu Kingdom. Chokun was born in 1684 as the son of the lord of Tamagusuku Magiri district. He showed genius at an early age and was given the job of magistrate of entertainments at the royal court. Chokun created the Kumi-odori, a theatrical performance art, for the entertainments presented to the Chinese investiture envoys who came to the Ryukyus to legitimatize the succession of the king. This style of tomb, known as Kamekobaka (turtle shell tomb), was made in the latter half of the 18th century. It is a rather rare type of tomb construction.
