How to Say ‘Was doing (polite past) / I was (doing)’ in Japanese

してました

shi te mashi ta

[shee teh mah-shee tah]

💬 Usage Tip: [してました] is the polite past progressive of [する]. Often used with feelings: [緊張してました] = “I was nervous.”

🇯🇵 In Japan: Admitting a little nervousness is seen as honest and cute rather than “weak,” especially early on.

Phrase Breakdown

shi

[shee]

do (stem)

Verb stem of する (“to do”). It combines with ていました to mean “was doing.”

Example

緊張 し てました。

I was nervous.

te

[teh]

-te (linking form)

Connects to いました/ました. In してました, it’s part of the past progressive/past state expression.

Example

ずっと待っ て ました。

I was waiting the whole time.

まし

mashi

[mah-shee]

polite past “was…” (shortened)

From いました → often shortened to ました/…ました in casual-polite speech. してました is a common spoken contraction of していました.

Example

さっきまで練習して まし た。

I was practicing until a moment ago.

ta

[tah]

past tense ending

た completes the polite past: ました. In speech, していました → してました (still polite but casual).

Example

緊張してまし た。

I was nervous.

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.
