Dekasegi

Dekasegi (decassegui, decasségui,, ) is a term that is used in Latin America to refer to people, primarily Japanese Brazilians and Japanese Peruvians, who have migrated to Japan, having taken advantage of Japanese citizenship or nisei visa and immigration laws to work short-term in Japan.

The original Japanese word dekasegi (出稼ぎ) roughly translates as "working away from home". This can cause irritation to those of Japanese descent who were born abroad, but have come to regard Japan as their permanent home and therefore object to being regarded by Japanese (in Japan) as gaijin or foreigners.

There are approximately 200,000 such people in Japan from Brazil alone.

Language
Some Brazilians are bilingual in Japanese and Portuguese, but many are monolingual in Portuguese alone when they first come to Japan and face additional challenges due to this language barrier. Many code-switch to Japanese when speaking Portuguese.
