How to Say ‘(polite) I tell you / you know’ in Japanese

ですよ

desu yo

[dess yoh]

💬 Usage Tip: [ですよ] adds gentle emphasis or “FYI” feeling: “It is (you know).” It can sound informative rather than pushy when said with a soft tone.

🇯🇵 In Japan: Tone matters: said warmly, [ですよ] sounds helpful; said sharply, it can sound like correcting someone. Listen for the mood!

What Learners Are Saying

Teaching in Osaka and I wanted to connect with my students beyond the classroom. The everyday conversation scenarios made my Japanese feel natural, not textbook-y.

Mia S., 25, English Teacher

Moved to Tokyo and the polite vs. casual speech levels were killing me. This app breaks it all down with real scenarios. My coworkers noticed the difference in weeks.

Kevin Z., 31, Game Developer

I tried five different apps before this one. The roleplay conversations are what finally made things click. I actually remember what I learn now.
