がいます means there is (someone) or (I) have (a person or animal). It is the polite way to say that a living, moving thing exists somewhere: a teacher in a classroom, a cat under the table, a brother in your family.
Japanese splits the English word “there is” into two verbs. いる / います is for people and animals. ある / あります is for everything else. がいます is the first half of that pair, and you will use it from your very first week of Japanese.
If it can walk away on its own, use います. If it can't, use あります.
What does がいます mean?
がいます is two pieces: the particle が, which marks the thing that exists, and います, the polite form of the verb いる (to exist, to be somewhere). Together they say “X exists.”
In English you translate it three different ways depending on the sentence:
- there is / there are — 公園に犬がいます。 “There is a dog in the park.”
- have — 妹がいます。 “I have a younger sister.”
- is (at a place) — when the person is already known: 母は台所にいます。 “My mother is in the kitchen.”
The “have” meaning surprises many learners. Japanese does not use a verb like “to own” for family members or pets. Instead it says the sister or the dog exists for you. So 犬がいます can mean both “there is a dog” and “I have a dog,” and the context tells you which.
How to form がいます
The core pattern is a noun for a living thing, the particle が, and います. Add a place with に in front when you want to say where.
The verb いる conjugates like any ru-verb. At N5 you need these four polite forms:
- います — there is (now / in general)
- いません — there isn’t
- いました — there was
- いませんでした — there wasn’t
Numbers of people and animals come after が, directly before います: 学生が三人います (there are three students). Use 〜人 for people and 〜匹 for small animals.
To ask who is there, use だれ: 部屋にだれがいますか。 (Who is in the room?) To ask where someone is, flip the order and use どこ: 田中さんはどこにいますか。
When is がいます used?
You reach for がいます in four everyday situations:
- Describing a scene. You are looking at a place and saying who or what is in it: a café full of students, a cat on the roof.
- Talking about family and pets. Self-introductions almost always include it: 兄が二人います。
- Asking whether someone is around. At a shop or office: 店員さんはいますか。
- Saying nobody is there. だれもいません (no one is here) is one of the most useful N5 phrases.
Register is simple. います is polite and fits any conversation with strangers, teachers, or coworkers. With friends and family you drop to the plain form いる: 猫がいる, いない, いた, いなかった. For customers and superiors, keigo speakers replace it with おります or いらっしゃいます, but that is N4 material.
がいます example sentences
Look at the second and third sentences: nothing in the Japanese says “own” or “have.” The family members and dogs simply exist, and English turns that into “I have.”
Nuance of がいます
The deciding question is animacy: is the thing alive and able to move by itself? People, dogs, fish, insects and birds take いる. Books, trees, houses, events and ideas take ある.
A few edge cases trip learners up:
- Plants are ある. A tree is alive but doesn’t move on its own, so it’s 木があります.
- Dead fish at the market are ある. Once an animal is food, it becomes an object.
- Taxis and buses can take いる when you think of the driver inside: タクシーがいます (a taxi is waiting). As an N5 learner, stick with ある for vehicles.
- Robots and characters often get いる in casual speech because people treat them as having a will.
There is also a nuance between が and は. が presents new information: 部屋に猫がいます introduces a cat the listener didn’t know about. When the person is already the topic, use は and say where they are: 猫は部屋にいます (the cat is in the room). The first answers “what’s in the room?”, the second answers “where’s the cat?”
Negatives switch to は. In negative sentences Japanese usually prefers は: 猫はいません (there's no cat). が+いません is not wrong, but は sounds more natural when you deny something.
がいます vs があります
These two are a pair. The grammar is identical; only the verb changes with the noun.
Same garden, same sentence shape, different verb. The full breakdown of the ある side is in があります. If you mix them up, Japanese speakers will still understand you, but 本がいます sounds as if the book is a living creature.
Common mistakes with がいます
Is がいます on the JLPT?
Yes. がいます is core JLPT N5 grammar and shows up in every section of the test.
Listening questions often describe a picture: “there are two people by the window and a cat on the sofa.” You pick the matching image, so you need to catch both the counter and the location.
