Japanese Byronites

Port Byron, the capital city of Patagonia, includes a Japanese community (Japanese: ニューダートマスの日本人), most of whom live in the Pembroke and Caithness districts. Pembroke includes a Japanese international school serving the community, Nankai Port Byron.

Most Japanese work in Port Byron for the Patagonian government as diplomats or embassy staff.

Geography
As of 2004 the majority of Port Byron's Japanese expatriate population lives in Pembroke. In 2005 there were 117,641 Japanese persons in Pembroke, making them the second largest foreign nationality and 3.57% of the commune's population. The presence of The Nankai Port Byron in the Pembroke area has attracted Japanese families with school-aged children to the area around the school. One street was named Nippon Avenue to commemorate the community.

As of 2013 Japanese live in the suburbs of Pembroke, Caithness, O'Grady, Nueva Cordova and Olleta.
