いる vs ある: How to Say “There Is,” “There Are,” and “Have” in Japanese Without Mixing Them Up

2026年6月18日

Picture this: you’re at a Japanese friend’s house, and you want to say “I have a dog.” You reach for your vocabulary, piece together a sentence, and say — 犬があります. Your friend pauses, then gently corrects you. What went wrong?

You used ある (arimasu) for a dog — a living creature. In Japanese, that’s one of the most common early mistakes. いる (います) and ある (あります) are both translated as “there is,” “there are,” or “have” in English, but Japanese makes a distinction that English simply doesn’t. Once you understand it, everything clicks into place.

This guide covers the full picture: the animate vs inanimate rule, how “have” splits between the two verbs, location patterns, gray zones like robots and plants, and the いる vs 入る（はいる）homophone trap that trips up even intermediate learners.

Why English Speakers Mix Up いる and ある

In English, one phrase does all the heavy lifting: “there is” and “there are.” You say “there is a person,” “there is a book,” “there is a problem” — the verb doesn’t change based on what you’re describing. The same goes for “have.” You “have” a sister, “have” a car, and “have” a plan. English doesn’t require you to think about the nature of what exists.

Japanese does. And that’s the root of almost every いる/ある mistake English speakers make.

The core rule is: いる is for animate things — people, animals, and living beings that move and act with their own agency. ある is for inanimate things — objects, places, events, plans, and abstract concepts.

But “animate” is a tricky word. It doesn’t simply mean “alive.” Plants are alive, but you use ある for them. A robot is not biologically alive, but in casual speech some speakers use いる. What really matters is whether the speaker perceives the thing as a living agent — something that moves, acts, and exists as an independent being. More on the edge cases in the gray zones section below.

What Does いる Mean?

いる（居る）means “to be” or “to exist,” and it applies specifically to animate beings. The polite form is います (imasu), the negative is いません (imasen), and the past is いました (imashita).

いる is used for:

People — family members, friends, teachers, strangers
Animals — dogs, cats, birds, fish, insects
Any living being that moves and acts with its own will

The location pattern is: [Place] に [Subject] がいます

Here are four natural example sentences:

📍 公園（こうえん）に子ども（こども）がいます。
There are children in the park.

📍 部屋（へや）に猫（ねこ）がいます。
There is a cat in the room.

📍 駅（えき）に駅員（えきいん）がいますか？
Is there a station attendant at the station?

📍 水槽（すいそう）に魚（さかな）がいます。
There are fish in the aquarium.

What Does ある Mean?

ある（有る／在る）also means “to be” or “to exist,” but for inanimate things. The polite form is あります (arimasu), the negative is ありません (arimasen), and the past is ありました (arimashita).

ある is used for:

Objects — books, keys, food, furniture
Buildings and places — stores, schools, hospitals, parks
Events and plans — 予定（よてい）がある, 会議（かいぎ）がある
Abstract things — 問題（もんだい）がある, 自信（じしん）がある, 時間（じかん）がある

The location pattern is: [Place] に [Subject] があります

Four natural example sentences:

📍 机（つくえ）の上（うえ）に本（ほん）があります。
There is a book on the desk.

📍 駅（えき）の前（まえ）にコンビニがあります。
There is a convenience store in front of the station.

📍 来週（らいしゅう）、会議（かいぎ）があります。
There is a meeting next week.

📍 このプロジェクトには問題（もんだい）があります。
There is a problem with this project.

いる / ある for “There Is” and “There Are”

Here is a side-by-side breakdown of how English “there is / there are” maps to Japanese:

English	Japanese	Verb	Why
There is a dog.	犬（いぬ）がいます。	いる	Animate (animal)
There is a teacher.	先生（せんせい）がいます。	いる	Animate (person)
There is a book.	本（ほん）があります。	ある	Inanimate (object)
There is a convenience store.	コンビニがあります。	ある	Inanimate (building/place)
There is a plan.	予定（よてい）があります。	ある	Abstract thing
There is a problem.	問題（もんだい）があります。	ある	Abstract thing

English hides this distinction completely. Japanese requires you to classify what exists before you choose your verb. Once you build that reflex, it becomes automatic — but it takes some deliberate practice at first.

いる / ある for “Have”

This is where many learners get tripped up. English “have” covers an enormous range of meaning — possessing objects, having family members, having time, having plans. Japanese splits all of this across いる, ある, and sometimes 持っている（もっている）.

Here is how it works:

兄（あに）がいます — I have an older brother. (person → いる)
犬（いぬ）がいます — I have a dog. (animal → いる)
車（くるま）があります — I have a car. (object → ある)
時間（じかん）があります — I have time. (abstract → ある)
予定（よてい）があります — I have plans. (abstract → ある)
お金（おかね）があります — I have money. (abstract → ある)

Notice the pattern: if what you “have” is a person or animal, use いる. If it’s an object, concept, time, money, or event, use ある.

When to use 持っている instead of ある

持っている（もっている）literally means “to hold” and implies physical possession — something you are carrying or currently holding in your hand. It works well for objects you carry:

傘（かさ）を持っています。 — I have an umbrella (with me right now).
鍵（かぎ）を持っていますか？ — Do you have a key (on you)?

But 持っている sounds unnatural — or even wrong — for non-physical things:

時間（じかん）を持っています ❓ — Technically understandable, but sounds stiff. 時間があります is far more natural.
予定（よてい）を持っています ❌ — Unnatural. Use 予定があります.
兄（あに）を持っています ❌ — Sounds like you’re carrying your brother. Use 兄がいます.

The safest rule: use 持っている only for physical objects you can literally hold or carry. For everything else — time, money, plans, family members, pets — follow the いる / ある split.

Wait, so if I want to say “I have a family,” I’d say 家族（かぞく）があります — right? Because family is a thing you have?

Rei

Actually, you’d say 家族がいます！ Family members are people — animate beings — so you use いる. Saying 家族があります treats your family like an object, which feels really cold in Japanese. いる shows that they are living, present people in your life.

Location Pattern: Place に Thing がいる / ある

When you want to say where something or someone is, Japanese uses a specific structure:

[Location] に [Subject] が [いる / ある]

に (ni) marks the location. が (ga) marks the subject — the thing that exists there. Then you choose いる or ある based on animate vs inanimate.

Examples:

部屋（へや）に猫（ねこ）がいます。 — There is a cat in the room.
机（つくえ）の上（うえ）に本（ほん）があります。 — There is a book on the desk.
駅（えき）の前（まえ）にコンビニがあります。 — There is a convenience store in front of the station.
教室（きょうしつ）に学生（がくせい）がいます。 — There are students in the classroom.

Common mistakes with location:

Forgetting に altogether: 部屋猫がいます ❌ → 部屋に猫がいます ✅
Using で instead of に: 部屋で猫がいます ❌ — で marks where an action takes place, not where something exists. Existence always uses に.

This に for existence vs で for actions is a subtle but important distinction. Remember: existence and location = に. Activity and action = で.

Gray Zones: When the Rule Is Not Clear

The animate/inanimate rule works cleanly for most situations, but Japanese has some genuinely ambiguous cases. Here is how to handle them:

Robots and machines — Technically inanimate, so ある is the default. But in casual conversation, especially when someone treats their robot like a companion, いる is acceptable and increasingly common. Neither sounds wrong; いる implies a personal, living relationship.

Dolls and stuffed animals — Usually ある, but children frequently say いる when they feel emotionally attached. Adults typically use ある in neutral contexts.

Insects and bugs — Use いる. They are living creatures that move independently. ゴキブリがいます (there’s a cockroach) is correct — and unfortunately very natural in summer in Japan.

Fish in a tank — いる, because they are living animals.

Plants — Despite being alive, plants are treated as inanimate in Japanese because they don’t move or act with intent. Use ある. 花（はな）があります — There are flowers. 木（き）があります — There is a tree.

Dead people / bodies — This one is context-dependent. In clinical or formal contexts (e.g., news reports, medical settings), ある may appear. In emotional or personal contexts — when talking about a loved one who has passed — many speakers use いる, because the person still feels present to them. Both can be heard; いる often carries more emotional warmth.

Practical advice: when in doubt, ask yourself whether the speaker treats the thing as a living agent with its own presence and will. If yes, lean toward いる. If not, use ある.

Yuka

I have a robot vacuum cleaner that I named Robo-kun. Is it ロボット掃除機（そうじき）がいます or ロボット掃除機があります?

Rei

Technically ある — it’s a machine, not a living thing. But if you say ロボット掃除機がいます, a Japanese speaker will understand you’re treating it as a little companion rather than just an appliance. Naming it Robo-kun makes いる feel quite natural! Both will be understood in casual conversation.

いる vs 入る: Don’t Confuse These Two

Japanese has a frustrating homophone trap for new learners: いる and 入る（はいる）sound similar and both relate to “being in a place” — but they mean completely different things.

いる（居る） — to exist, to be (somewhere). Describes a state of existence.
入る（はいる） — to enter, to go into. Describes an action of movement.

Compare these pairs:

Pair 1 — Being in the room vs entering the room:

部屋（へや）にいます。 — I am in the room. (existence / state)
部屋（へや）に入ります（はいります）。 — I enter the room. (action / movement)

Pair 2 — Being in the bath vs getting into the bath:

お風呂（ふろ）にいます。 — I am in the bath. (I am currently bathing)
お風呂（ふろ）に入ります（はいります）。 — I will get into the bath. (the act of getting in)

English “be in” blurs this distinction — you can “be in the room” whether you just walked in or have been sitting there for an hour. Japanese separates the action of entering (入る) from the ongoing state of being there (いる). Keep this distinction in mind, especially when talking about rooms, baths, buildings, and vehicles.

Common いる vs ある Mistakes English Speakers Make

These are the errors that come up again and again in learner conversations and on language exchange apps. Run through them once and you’ll save yourself a lot of awkward corrections.

❌ 犬（いぬ）があります → ✅ 犬がいます — Dogs are animate; always いる.
❌ 本（ほん）がいます → ✅ 本があります — Books are inanimate; always ある.
❌ 家族（かぞく）があります → ✅ 家族がいます — Your family are people, not objects. Using ある sounds cold and unnatural.
❌ 予定（よてい）がいます → ✅ 予定があります — Plans and schedules are abstract; always ある.
❌ 時間（じかん）を持っています (for “I have time”) — This is technically understandable but unnatural. Use 時間があります instead.
❌ 部屋で猫がいます → ✅ 部屋に猫がいます — Existence uses に, not で.
❌ 部屋にいります (confusing いる with 入る) → います for existence, 入ります for entering.

Yuka

I’ve definitely said 家族があります before. I feel a bit embarrassed now…

Rei

Every Japanese learner makes this mistake early on — it’s completely normal! The good news is that Japanese speakers will always understand what you mean. Once you know the animate rule, you’ll catch yourself naturally. You’ve already taken the hardest step by learning the rule.

Decision Rule: いる or ある?

Use this flowchart whenever you’re unsure which verb to choose:

Is it a person or animal?
  → Yes: いる / います

Is it an object, building, or place?
  → Yes: ある / あります

Is it an event, plan, or abstract thing?
  → Yes: ある / あります

Is it something you're treating as alive (robot, doll)?
  → Probably いる in casual speech

Are you saying someone "has" a family member or pet?
  → いる

Are you saying someone "has" an object, time, or money?
  → ある

Still unsure? Ask: does it move and act on its own?
  → Yes: いる
  → No: ある
