“〜ta mono da・〜te ita mono da”: I Used to 〜 (fondly recalling) [JLPT N3]
By Nihongo to Japan · Updated July 3, 2026
“Kodomo no koro yoku asonda mono da” — nostalgic reflection on past habits
“〜ta mono da・〜te ita mono da”: I Used to 〜 (looking back fondly)
「verb た-form ＋ ものだ」 is used to recall, with nostalgia, things you often did in the past — “I used to 〜.” E.g. 「子供のころ、よく遊んだものだ」 (I used to play a lot as a kid), 「昔はよく食べていたものだ」 (I used to eat that a lot). It's not a plain statement of the past, but an emotional reflection and reminiscence.
🧠 Core nuance: not just “did,” but “fondly remember doing it often”
The key is that nostalgic, wistful feeling: standing in the present, the speaker looks back on a time when something “often happened,” with a tone of “those were the days.” That's why it pairs with 昔, 子供のころ, 若いころ, よく — the whole sentence gives off a warm, reminiscent glow.
📌 How to Connect
| Form | Pattern | Example |
|---|---|---|
| verb た-form ＋ ものだ | past habit | よく遊んだものだ |
| 〜ていた ＋ ものだ | an ongoing past habit | よく食べていたものだ |
| Common combo | 昔・子供のころ・よく ＋ 〜たものだ | 昔はよく喧嘩したものだ |
💬 Example Sentences
- 若いころは、徹夜で遊んだものだ。(I used to stay up all night having fun.) — nostalgic youth

🔄 Compare: たものだ vs (present) ものだ vs ていた vs ものか
| Expression | Meaning | Example |
|---|---|---|
| 〜たものだ | nostalgic recollection of a past habit | よく遊んだものだ |
| 〜ものだ (present) | general truth / common sense / exclamation | 親には感謝するものだ |
| 〜ていた | plain past continuous (no nostalgia) | 遊んでいた |
| 〜ものか | strong denial (no way 〜!) | 負けるものか |
⚠️ Common Mistakes
- Using the dict. form for recollection: ✗ よく遊ぶものだ (meaning a past memory) → ✓ よく遊んだものだ (た-form).
- Confusing it with ものか: ものか is the “no way 〜” denial, unrelated to nostalgic ものだ.
- Using it for present habits: たものだ refers strictly to the past.
- Wrong connection: ✗ 遊びものだ／遊んでものだ → ✓ 遊んだものだ.
💡 Nuance & When to Use
たものだ is perfect for reminiscing and wistful reflection — swapping old stories with friends, writing a memoir-style piece, or an elder recalling their youth. It adds warmth and sentiment. Note it's an emotional recollection; for plain factual statements in formal reports, use 〜ていた instead.
🎯 JLPT Exam Tips
- High-frequency N3: 昔・子供のころ・よく ＋ た-form ＋ ものだ = nostalgic recollection.
- Distinction: separate it from dictionary-form ものだ (truth) and ものか (denial).
- Connection items: recollection uses the た-form, not the dictionary form.
