[2] Irabu Island is also connected via six bridges to Shimoji-shima.

[1] There are multiple language variants spoken on the island: Nakachi-Irabu, Kuninaka, Sawada-Nagahama, and Sarahama (which is a variant of Ikema language spoken by descendants of emigrants from Ikema Island).

[3] The term comes from the Japanization of the Miyakoan name Irav, in turn from Proto-Ryukyuan *erabu (tone class B).

Cognates in other Ryukyuan languages include Okinoerabu irabu, referring to Okinoerabujima.
