Uruma
The Okinawan origin of the word, however, has long been questioned. In fact, it was in mainland Japan that the word was first attested and eventually came to refer to Okinawa. The first known reference to "uruma" is a waka poem by Fujiwara no Kintō in the early 11th century. He compared a woman's coldheartedness to the incomprehensible speech of drifters from "Ureung" Island (迂陵島, identified as Ulleung Island) of Goryeo Kingdom, which Kintō called Silla, a practice rather common in Heian-period Japan. However, the association with Ulleung Island was soon forgotten because the reference to Silla was dropped when his poem was recorded in the "Senzai Wakashū" (1188). Thereafter waka poets only thought "uruma" as an island somewhere outside Japan with an unintelligible language. At the same time, it evoked a sense of familiarity because the phrase "uruma no ichi" (market in Uruma) was poetically associated with Mino Province. From the viewpoint of mainland Japanese poets, Okinawa might have been an ideal referent of "uruma" because, despite the exotic name of "Ryūkyū", the first reference to Okinawan-composed waka poems was as early as 1496. The first known identification of "uruma" as Okinawa Island can be found in the "Moshiogusa" (1513), but the association remained weak for some time. For example, Hokkaido, in addition to Okinawa, was referred to as "uruma" in the "Shōzaishū" (1597). The mainland Japanese poetic practice was adopted by Okinawan waka poets in the late 17th century. The "Omoidegusa" (1700), a purely Japanese poetic diary by Shikina Seimei, is known for its extensive use of the word "uruma".
