Yuka中古 vs 使用済み — both involve something that's been used before, but they carry very different meanings. Let's sort out the difference!
ReiThis is an important distinction — especially if you're shopping in Japan or using second-hand apps like メルカリ!
At a Glance
| Word | Reading | Meaning | Nuance |
|---|---|---|---|
| 中古 | ちゅうこ | Used, second-hand | Implies the item can still be used; sold as pre-owned |
| 使用済み | しようずみ | Used up, already used | Implies the item has been consumed or worn out; often not reusable |
中古 (ちゅうこ) — Second-Hand, Pre-Owned
中古 means used or second-hand — but with the implication that the item is still functional and worth selling or buying again. The kanji 中 (middle) + 古 (old) suggests it's somewhere between new and worn-out.
You'll see 中古 on:
- 中古車 — used car
- 中古品 — second-hand goods
- 中古マンション — pre-owned apartment
- 中古ショップ — second-hand shop
Yuka中古車を買ったんだけど、状態がすごくいい！
I bought a used car, but it's in really good condition!
| Japanese | English |
|---|---|
| メルカリで中古のゲームを売った。 | I sold a used game on Mercari. |
| 中古のパソコンでも十分だよ。 | Even a second-hand computer is fine. |
| この中古マンション、すごく安い。 | This second-hand apartment is really cheap. |
使用済み (しようずみ) — Already Used, Used Up
使用済み means already used — with the nuance that the item has been consumed, spent, or drained of its original purpose. It often implies the item is no longer suitable for use.
Common uses:
- 使用済みの電池 — used-up batteries
- 使用済みのテレホンカード — a used-up phone card
- 使用済みのマスク — a used mask (already worn)
- 使用済み切手 — a used stamp
ReiNotice: 使用済みの電池 means the battery is dead — it's used up. 中古の電池 would be weird — you don't resell used batteries as pre-owned goods. The difference is about reusability and resale value.
| Japanese | English |
|---|---|
| 使用済みの電池は捨てないでください。 | Please do not throw away used batteries (recycle them). |
| 使用済みのシリンジは危険です。 | Used syringes are dangerous. |
| これは使用済みのカード入れです。 | This is a box for used cards. |
Key Difference: Resale vs. Disposal
| 中古 | 使用済み | |
|---|---|---|
| Reusable? | Yes — still functional | Usually no — consumed or worn out |
| Resale value? | Yes — can be sold as second-hand | No — typically discarded |
| Common context | Shopping, cars, electronics | Waste, safety, recycling |
| Example | 中古車、中古品 | 使用済み電池、使用済み注射器 |
