Meaning

Let's discuss it on chat (Slack, Teams, etc.) — a common redirect phrase when email or in-person discussion isn't the best channel.

A simple but culturally significant phrase that reflects the shift in Japanese workplace communication from email to chat tools like Slack, Microsoft Teams, and Chatwork. Saying 'チャットで' is a quick way to move a conversation to a more efficient channel. It also signals a more casual, fast-paced communication style that younger workers prefer over formal email exchanges.

Examples

1. その件、チャットで詳しく送るね。 I'll send you the details about that on chat.
2. 今メール書くの面倒だからチャットで話さない？ Writing an email right now is a hassle — can we just talk on chat?
3. チャットで聞いた方が早いよ、メールだと返信遅いから。 It's faster to ask on chat — email replies take forever.

Usage Guide

Context: workplace, email sign-offs, quick exchanges

Tone: efficient, casual

Do Say

• この話、チャットで続きやりましょう。 (Let's continue this discussion on chat.)
• チャットで資料共有するから、確認しておいて。 (I'll share the materials on chat, so check them.)

Don't Say

• 公式な依頼や重要な決定は「チャットで」にしない方がいい — 記録が残りにくい (Don't handle official requests or important decisions via chat — the record trail is weaker)

Common Mistakes

• Assuming everyone in a Japanese company uses chat — many traditional companies still rely heavily on email
• Using chat for messages that should be emails in formal contexts
