恋愛
れんあい
renai
= romantic love; romance
恋愛 (renai) is romance as a whole — the concept and activity of romantic love, dating, and relationships. When Japanese talks about love as a topic rather than a single fluttering feeling, 恋愛 is the word, from 恋愛映画 (romance films) to 職場恋愛 (office romance).
恋愛 names romantic love in the abstract and works as a noun and a する-verb: 恋愛する (to be in a romantic relationship), 恋愛関係 (a romantic relationship), 恋愛観 (one’s view on love). It is the umbrella term for the whole business of romance, which is why it appears in so many compounds about dating and relationships.
It helps to line 恋愛 up against 恋 and 愛. 恋 (koi) is the feeling of being in love — the flutter, the longing, the crush — an emotional, often bittersweet single feeling. 愛 (ai) is love in a deep, broad sense that includes family, humanity, and lasting devotion. 恋愛 sits between and around them as the concept of romantic relationships: the dating, the couplehood, the topic itself. A neat traditional saying holds that 恋 can mature into 愛, and 恋愛 is the arena where that happens.
You will meet 恋愛 in many everyday compounds: 恋愛結婚 (a love marriage, chosen by the couple) as opposed to お見合い結婚 (an arranged-introduction marriage), 遠距離恋愛 (a long-distance relationship), and 社内恋愛 or 職場恋愛 (a workplace romance). In each, 恋愛 supplies the ‘romantic-relationship’ meaning that the rest of the compound specifies.
Don’t reach for 恋愛 when you mean the feeling of a crush — that’s 恋 or 好き. 恋愛 is the concept or activity, so 恋愛している leans toward ‘I’m in a relationship / dating’, while 恋をしている is more ‘I’ve fallen for someone’.
Remember 恋愛 takes する, so ‘they’re dating’ can be 恋愛している or, more commonly in speech, 付き合っている (tsukiatte iru).
Use the compounds to sound natural: a couple who married for love is a 恋愛結婚, a long-distance couple is doing 遠距離恋愛, and dating a coworker is 職場恋愛 — each is a fixed, everyday term rather than something to translate word by word.
Casual / Social Media
今は仕事が忙しくて、恋愛どころじゃない。
Ima wa shigoto ga isogashikute, renai dokoro ja nai.
I’m so busy with work right now that romance is out of the question.
Everyday use
週末は恋愛映画を観て泣くのが好きです。
Shuumatsu wa renai eiga wo mite naku no ga suki desu.
On weekends I like watching romance films and crying.
Formal / Cultural context
社内恋愛は、周りに気を使うので大変らしい。
Shanai renai wa, mawari ni ki wo tsukau node taihen rashii.
Office romance is apparently tough because you have to be mindful of everyone around you.
The word carries real social history. For much of Japan’s past, marriages were arranged through お見合い (omiai, formal introductions), and the 恋愛結婚 (love marriage) only overtook arranged marriage as the norm in the mid-20th century. Because of this, 恋愛 versus お見合い remains a meaningful cultural contrast, and 恋愛結婚 still marks a marriage that grew from the couple’s own romance.
恋愛 is also a massive entertainment category. Manga, anime, films, and especially 恋愛ゲーム (dating-sim games) and 乙女ゲーム (otome games aimed at women) build entire worlds around romance, complete with genre conventions the audience knows by heart. For many overseas fans, this media is a first encounter with the word, and 恋愛もの (‘romance-type’ stories) is a shelf label as familiar as ‘rom-com’ in English.
In recent years 恋愛 has become a topic of genuine social debate. Commentators point to young people described as 草食系 (herbivore types) who show less interest in dating, and to surveys about declining 恋愛 among youth tied to economic pressure and changing values. The word thus sits at the center of conversations about relationships, marriage rates, and the future of Japanese society.
