Freeter and Arubaito

Freeter (フリーター furītā^?) is a Japanese expression for young people subsisting on part-time work, who lack full-time employment or are unemployed, excluding housewives and students.

These people do not start a career after high school or university, but instead earn money from low skilled and low paid jobs.

If they work at all, freeters often work at convenience stores, supermarkets, fast food outlets, restaurants, and other low paying, low skill jobs.

The word freeter or freeta was first used around 1987 or 1988 and is thought to be a portmanteau of the English word free (or perhaps freelance) and the German word Arbeiter ("labourer").  

Arubaito (part-time job) is a Japanese loanword from German. As German (along with English) was used (especially for science and medicine) in Japanese universities before World War II, Arubaito became common among students to describe part-time work for university students.
