バイト
ばいと
baito
= part-time job / to work part-time
バイト (baito) is the casual Japanese word for a part-time job — a word borrowed from German (Arbeit, meaning work) that became so thoroughly Japanese that most speakers have no idea of its European origin.
Baito is a shortened form of アルバイト (arubaito), itself borrowed from the German word Arbeit (labor/work). It refers to part-time or temporary employment, as distinct from seishain (正社員, full-time permanent employee). Baito is the casual noun form; the verb form is バイトする (baito suru, to work a part-time job) or バイトをする (baito wo suru). In Japan, baito is an extremely common way of working — most students, young adults, and people between jobs take baito positions at convenience stores, restaurants, cafes, and retail shops.
The full form アルバイト (arubaito) and the shortened バイト (baito) are interchangeable in casual speech. Arubaito sounds slightly more formal or careful; baito is the everyday word. The place where you do baito is your バイト先 (baito-saki). A person who works baito is a バイト (also used as a noun for the worker: ‘バイトを雇う’ — to hire a part-time worker).
Everyday use

Formal / Cultural context
日本の大学生の多くは学費や生活費を賄うためにバイトをしている。
Nihon no daigakusei no ooku wa gakuhi ya seikatsuhi wo makanau tame ni baito wo shite iru.
Many Japanese university students work part-time jobs to cover tuition and living expenses.
Part-time work (バイト) plays a central role in the lives of Japanese students and young adults. The convenience store (コンビニ, konbini) and fast food industries rely heavily on baito workers, and the experience of working a service job is so common that it has become a shared cultural touchpoint — characters in manga and anime frequently have baito storylines that explore responsibility, customer service culture (お客様は神様, the customer is god), and the social dynamics of a part-time workplace.
The path from baito to full-time employment in Japan is significant. Baito workers are typically paid hourly and receive no benefits, job security, or bonuses — a stark contrast to the seishain (正社員) system. This distinction is socially meaningful: being a seishain carries status and stability, while relying solely on baito into one’s 30s can carry social stigma. The rise of non-traditional work arrangements and the ‘freeter’ (フリーター — a person who relies primarily on baito) phenomenon have made this distinction a topic of ongoing social discussion.
