Translation guide
To begin to feel romantic love for someone. In Japanese, this is most commonly expressed with the phrase 恋に落ちる (koi ni ochiru), but there are also other natural expressions depending on the nuance and context.
Express the act of falling in love in a general sense.
The most direct and common translation. It literally means 'to fall into love' and is used for romantic love.
彼は彼女に恋に落ちた。
He fell in love with her.
I fell in love at first sight.
Literally 'to come to like'. This is a softer, more casual way to say you've developed feelings for someone. It can range from a crush to deeper affection.
彼のことが好きになった。
I fell for him. / I started to like him.
いつの間にか好きになっていた。
Before I knew it, I had fallen in love.
A more colloquial and sometimes stronger term meaning 'to fall for' or 'to be charmed by'. Often used in casual speech.
彼女にすっかり惚れてしまった。
I've completely fallen for her.
Literally 'to do love'. It means to be in love or to experience love, but can also imply the process of falling in love. Slightly more literary.
彼は初めて恋をした。
He fell in love for the first time.
Specifically express falling in love instantly upon first meeting.
Express falling in love over time, without a clear moment.
Means 'to come to like before one knows it'. Emphasizes the gradual, unconscious process.
いつの間にか彼を好きになっていた。
I had fallen in love with him before I knew it.
Similar to above, meaning 'when I realized, I had fallen for them'.
気づいたら彼女のことが好きになっていた。
When I realized it, I had fallen in love with her.
Express falling intensely or passionately in love.
Adds 深く (deeply) to the standard phrase.
彼女は深く恋に落ちた。
She fell deeply in love.
Means 'to fall violently/passionately in love'. Stronger nuance.
二人は激しく恋に落ちた。
The two fell passionately in love.
Literally 'to be flushed/head over heels'. Implies being infatuated or madly in love, often with a slightly negative connotation of losing one's head.
恋に落ちる is more dramatic and explicitly romantic, often implying a sudden event. 好きになる is softer, more gradual, and can be used for any kind of liking, not just romantic love. In casual conversation, 好きになる is very common and natural.
彼に恋に落ちた。
I fell in love with him (dramatic, romantic).
彼のことが好きになった。
I started to like him (softer, could be romantic or platonic).
Do not translate 'fall' literally as 落ちる without 恋に. 落ちる alone means to physically fall or drop, and will not be understood as falling in love.
あなたに恋をしているみたい。
I think I'm falling in love with you.
Uses 恋をしている (to be in love) to express the ongoing process.
二人は恋に落ちて結婚した。
They fell in love and got married.
彼は彼女にのぼせ上がっている。
He's head over heels in love with her.
