Meaning

Direct message — a private message sent to someone on social media, separate from public posts or comments.

DM (ダイレクトメッセージ) is the standard term for private messaging on platforms like Twitter/X, Instagram, and Facebook. In Japan, DMs are a common way to shift from public interaction to private conversation. Saying 'DM送るね' (I'll DM you) is a signal that something is too personal, detailed, or sensitive for public posting. DMs are also how many online friendships and relationships begin, and the phrase 'DMは開放してます' (my DMs are open) is common in bios.

2. 知らない人からDM来てちょっと怖い。 I got a DM from a stranger and it was kind of creepy.
3. DMでやりとりしてたら意外と話が合って仲良くなった。 We were chatting over DMs and turns out we really click.
