Common Japanese Mistake: いる (iru) vs ある (aru) — Animate vs Inanimate

Two “To Be/Have/Exist” Verbs

Japanese uses two verbs where English uses “there is/are” or “to have”: いる for animate things (people and animals) and ある for inanimate things (objects, events, abstract things). Mixing these up is a very common beginner mistake.

The Rule

Common Mistakes

The Robot / Doll Grey Zone

Robots and stuffed animals/dolls can use either, depending on how the speaker feels about them:

• 「ロボットがあります。」— There is a robot (treating it as an object).
• 「ロボットがいます。」— There is a robot (treating it as a character/being).

In modern usage, people often use います for robots, AI characters, and even beloved objects.

Using いる/ある for “Have”

Japanese doesn’t have a separate verb for “have” — use いる/ある:

• 「いもうとがいます。」— I have a younger sister.
• 「じかんがあります。」— I have time.
• 「おかねがありません。」— I don’t have money.

Quick Drill: います or あります?

1. きょうしつにがくせい___。(students in classroom)
2. つくえのうえにほん___。(book on desk)
3. わたしには あに___。(I have an older brother)
4. きょうはしけん___。(there is an exam today)

Answers: 1. がいます / 2. があります / 3. がいます / 4. があります

Yuka Mixes Up いる and ある

Mistakes feel embarrassing in the moment but they are the fastest way to learn. Watch how Yuka makes a natural error — and how Rei explains the rule clearly enough to prevent it from happening again.

Yuka

Rei, I always get いる and ある confused. I wrote テーブルにコップがいます and my friend laughed.

Rei

Ha! いる is for living things — people, animals. ある is for non-living things — objects, places, events. A glass (コップ) is not alive, so: テーブルにコップがあります.

Yuka

So: 猫がいます for a cat, and 本があります for a book?

Rei

Perfect! And it extends further: 来週、テストがあります — There is a test next week (event, not alive). 彼女がいます — I have a girlfriend (person). Once you have living vs non-living, it clicks.

Yuka

What about robots or stuffed animals? Are they いる or ある?

Rei

Technically ある since they’re not alive. But if a robot is being treated as a person or character — like in an anime — speakers often use いる to express that personhood. Language reflects emotion. The ‘wrong’ choice can actually communicate something meaningful!
