オンライン

• Reading: オンライン
• Romaji: onrain
• Pronunciation: /oŋ.ɾa.iŋ/

Meaning

Online — connected to the internet, or available on a platform. Also used for remote activities like online classes or shopping.

Direct loanword from English 'online.' The COVID-19 pandemic massively expanded the use of this word beyond tech contexts. オンライン授業 (online classes), オンライン飲み会 (online drinking parties), and オンライン診療 (online medical consultations) became everyday terms. The word now implies 'remote/virtual' as much as 'connected to the internet.'

Examples

1. コロナ以降オンラインで買い物することが増えた。 Since COVID, I've been shopping online way more.
2. 今日の会議オンラインだからカメラオンにしてね。 Today's meeting is online, so make sure your camera is on.
3. オンラインゲームで知り合った友達とオフ会した。 I met up in person with friends I made through an online game.
