This paper discusses four different linguistic landscapes in Okinawa Prefecture: Naha Airport, Yui Monorail, Heiwadōri Market and Yonaguni Island. In addition to Japanese, Ryukyuan local languages are spoken there – Uchinaaguchi in Okinawa and Dunan in Yonaguni. Okinawan Japanese (Ryukyuan-substrate Japanese) is also used. In the linguistic landscapes these local languages and varieties are rarely represented and, if they are, they exhibit processes of language attrition. The linguistic landscape reproduces language nationalism and monolingual ideology.
