If you’ve ever looked at a sentence like 「窓が開いている」 and 「窓が開けてある」 and wondered why they both seem to mean “the window is open” — you’re not alone. This is one of the most common points of confusion for intermediate Japanese learners.
Both grammar forms describe a resulting state, but they come from completely different perspectives. Once you understand who caused the state and why, the difference becomes clear and easy to apply.
Let’s break it all down.
Here’s a quick snapshot before we dive in:
| 〜ている | 〜てある | |
|---|---|---|
| Verb type | Intransitive (自動詞) | Transitive (他動詞) |
| Implies a doer? | No | Yes (implied) |
| Implies intention? | No | Yes |
| Focus | Observation of a state | Deliberate result |
| Key particle | が | が (object promoted to subject) |
1. What Does 〜ている Mean?
〜ている (te-iru) has several uses in Japanese, but when attached to a change-of-state verb, it expresses a resulting state — the current condition that exists after an action happened.
The key point: 〜ている is neutral. It simply observes that a state exists. There is no implication about who caused it or why.
Formation note: The て-form (te-form) is a conjugation base used to connect verbs. For example: 開く → 開いて, 閉まる → 閉まって, 落ちる → 落ちて. Add いる after the て-form to get 〜ている.
Formation
Verb (て-form) + いる
Examples
| Japanese | English |
|---|---|
| 窓が開いている。 | The window is open. (= it’s in an open state) |
| 財布が落ちている。 | A wallet has fallen. (= it’s lying there) |
| ドアが閉まっている。 | The door is closed. |
| 電気がついている。 | The light is on. |
English speaker tip: The closest translation is often the English present perfect or simple present used to describe a state: “The window is open,” “The door is closed.” But unlike English, the Japanese verb is intransitive here — the subject is the thing being in a state, not the person acting on it.
What verbs work with 〜ている (state meaning)?
These are typically intransitive (自動詞, jidoshi) verbs — verbs where something happens to a subject, not verbs where someone does something to an object.
| Intransitive (〜ている) | Meaning |
|---|---|
| 開く (aku) | to open (by itself) |
| 閉まる (shimaru) | to close (by itself) |
| 落ちる (ochiru) | to fall |
| 消える (kieru) | to disappear / go out |
2. What Does 〜てある Mean?
〜てある (te-aru) also describes a resulting state — but it carries a crucial extra layer of meaning: someone intentionally did something, and the result of that action remains visible.
The focus is on the purposeful human action behind the state. There is always a “doer” implied, even if that person is not mentioned.
Formation note: 〜てある also uses the て-form, but it attaches to transitive verbs instead. For example: 開ける → 開けて, 書く → 書いて, 作る → 作って. Add ある after the て-form to get 〜てある.
Formation
Transitive verb (て-form) + ある
Important: 〜てある almost exclusively attaches to transitive (他動詞, tadoshi) verbs — verbs where someone acts on an object. The object of that action becomes the grammatical subject.
Examples
| Japanese | English |
|---|---|
| 窓が開けてある。 | The window has been opened (by someone, on purpose). |
| 予約がしてある。 | A reservation has been made (and it’s still valid). |
| 名前が書いてある。 | A name is written (someone wrote it there). |
| 料理が作ってある。 | Food has been prepared (and is ready). |
English speaker tip: Think of 〜てある as “it’s been done — and the result is there for a reason.” It implies preparation, intention, or consequence. A useful mental shortcut: someone left it that way on purpose.
3. Side-by-Side Comparison
Here is the clearest way to see the difference:
| 〜ている | 〜てある | |
|---|---|---|
| Verb type | Intransitive (自動詞) | Transitive (他動詞) |
| Subject | The thing in a state | The thing acted upon |
| Implies a “doer”? | No | Yes (implied) |
| Implies intention? | No | Yes |
| Focus | Observation of a state | Result of a deliberate action |
Minimal pair: 窓
| Japanese | Nuance |
|---|---|
| 窓が開いている。 | The window is open. (Just an observation — maybe the wind blew it open, maybe someone opened it, we don’t know.) |
| 窓が開けてある。 | The window has been opened (by someone, intentionally — perhaps for ventilation). |
Both sentences translate to “the window is open” in English, but the Japanese makes the reason and agency explicit.
4. Common Mistakes and How to Avoid Them
Mistake 1: Using 〜ている with a transitive verb for a state
Saying「テーブルに料理を置いている」to mean “the food has been placed on the table” sounds odd — it sounds like someone is in the process of placing the food right now.
Correct: 「テーブルに料理が置いてある」— The food has been set on the table (it was placed there, ready to eat).
Particle note: The particle also shifts. With transitive verbs + 〜ている, the object takes を (action is ongoing). With 〜てある, the object is promoted to subject position with が (the result is foregrounded).
Mistake 2: Confusing progressive meaning with state meaning
Remember, 〜ている has two meanings:
- Progressive (ongoing action): 「食べている」= I am eating (right now)
- Resulting state: 「窓が開いている」= The window is open (state)
Context and verb type tell you which meaning applies. Change-of-state verbs (open, close, fall, die) naturally lean toward the state meaning.
Mistake 3: Forgetting the transitive/intransitive pair
Japanese has many verb pairs where one is transitive and one is intransitive. You must use the correct one:
| Intransitive → 〜ている | Transitive → 〜てある |
|---|---|
| 開く (aku) — window opens | 開ける (akeru) — to open a window |
| 閉まる (shimaru) — door closes | 閉める (shimeru) — to close a door |
| 消える (kieru) — light goes out | 消す (kesu) — to turn off a light |
| つく (tsuku) — light turns on | つける (tsukeru) — to turn on a light |

Summary
The difference between 〜ている and 〜てある comes down to one key question: was this done on purpose by someone?
- 〜ている = a state exists. Neutral observation. Uses intransitive verbs.
- 〜てある = a state exists because someone deliberately caused it. Uses transitive verbs.
Once you start noticing this distinction in native Japanese — in conversations, dramas, and everyday signs — you’ll realize how frequently it comes up. Mastering it is a genuine step toward natural, fluent Japanese.
Quick Quiz: Test Yourself
Try translating these into Japanese using the correct form:
Q1. The ticket has been bought (and is ready). → Hint: 買う (kau)
Q2. The lights are off. → Hint: 消える (kieru) / 消す (kesu)
Q3. A message has been written. → Hint: 書く (kaku)
Q4. The food is ready (someone prepared it for the party). → Hint: 作る (tsukuru)
Q5. The door is closed. (neutral observation, no implied doer) → Hint: 閉まる (shimaru)
Answers:
- チケットが買ってある。 — 〜てある because someone intentionally bought it and the result (the ticket) is in hand.
- 電気が消えている。 — 〜ている because 消える is intransitive; we observe the state without implying a doer.
- メッセージが書いてある。 — 〜てある because 書く is transitive and someone deliberately wrote it.
- 料理が作ってある。 — 〜てある because 作る is transitive and the preparation was intentional (for a purpose).
- ドアが閉まっている。 — 〜ている because 閉まる is intransitive; just a neutral observation of the state.
