告る

• Reading: こくる
• Romaji: kokuru
• Kanji breakdown: 告 (confess/tell) + る (verb suffix) → to confess love
• Pronunciation: /ko.kɯ.ɾɯ/

Meaning

To confess romantic feelings to someone; to make a love confession.

告る is the abbreviated verb form of 告白する (kokuhaku suru, to confess). In Japanese dating culture, formally confessing your feelings is a crucial step — relationships typically do not begin without a clear 告白. 告る is the casual, slangy way to describe this act, commonly used among young people. The moment of 告る is treated as a significant, nerve-wracking event.

Examples

1. 明日あの子に告ろうと思ってるんだけど、緊張する。 I'm thinking of confessing to that person tomorrow, but I'm so nervous.
2. 友達が卒業式の日に告ったらしいよ。 Apparently my friend confessed on graduation day.
3. 告るタイミングが分からなくて3年片思いしてた。 I couldn't figure out when to confess, so I had a one-sided crush for three years.

Usage Guide

Context: friends, school, dating, social media

Do Say

• 告る前にLINEで仲良くなっておいたほうがいいよ。 (You should get closer on LINE before you confess.)
• 告られたけど好きじゃなかったから断っちゃった。 (Someone confessed to me but I didn't like them, so I turned them down.)

Don't Say

• 初対面の人にいきなり告るのは引かれる (Confessing to someone you just met is off-putting — build a connection first)

Common Mistakes

• Thinking 告る is just asking someone out — in Japanese culture it is a formal declaration of feelings, not a casual date invitation
