リア充

• 読み: リアじゅう
• ローマ字: riajū
• 漢字の分解: リア (from リアル, 'real') + 充 (jū, fulfilment/充実) → someone fulfilled in real life
• 発音: /ɾi.a.dʑɯː/

意味

Someone who is fulfilled and thriving in real life, especially in terms of romance, social life, and real-world activities.

リア充 originally emerged on 2channel as a somewhat envious or ironic label used by self-described otaku and internet-dwellers to describe people who seemed to be enjoying a rich offline life — particularly those with romantic partners and active social lives. Over time, it has become more mainstream and can be used self-deprecatingly ('I'm not a リア充') or as a light-hearted observation. The term reflects the perceived divide between online and offline lifestyles in Japan.
