Iha Fuyū (1876–1947) was born in Naha as the eldest son of a lower-class pechin.

Four years later in 1895, he was dismissed due to leading strikes calling for the principal to resign after he dropped English from the school's curriculum.

In 1921, he was formally appointed as the director of Okinawa Prefectural Library but resigned three years later and moved to Tokyo to further his studies.

Then, on August 13, 1947, Iha Fuyū died in Tokyo at the house of fellow Okinawan historian Higa Shuncho.

[citation needed] Omoro Sōshi is a collection of songs, 1553 poems and 1267 poems (when the same songs are excluded) in 22 volumes, starting in the middle of the thirteenth century and ending in the middle of the seventeenth century.

Omoro is the abbreviation of Omori uta, or songs sung in the sacred places of Ryukyu.

The themes of the Omoro include the origin of Ryukyu, kings, heroes, voyages, poets, sceneries, heaven and stars, and very rarely romance.
