Expressing Wants in Japanese: 〜たい, ほしい, and 〜てほしい Explained

You see a beautiful piece of wagashi at a Japanese confectionery and think, “I want to eat that.” Later, your friend keeps interrupting you while you study, and you wish they would just be quiet. That evening, browsing an online store, you spot a limited-edition notebook — you want it. Three perfectly ordinary desires. Three completely different Japanese grammar patterns.

Expressing wants in Japanese isn’t complicated, but the language draws a careful distinction between wanting to do something yourself, wanting a thing, and wanting someone else to do something for you. Get the pattern wrong and your sentence either sounds unnatural or means something you didn’t intend. This guide covers all three — 〜たい（たい）, ほしい（ほしい）, and 〜てほしい（てほしい）— plus the all-important third-person rules that trip up even intermediate learners.

〜たい: Expressing Your Own Desire to Act

The pattern 〜たい attaches to the masu-stem of a verb (the part you see before ます in the polite form) and means “I want to [do something].” It is exclusively about your own desire to perform an action — not an object you want to possess.

Formation: [Verb masu-stem] + たい

Conjugating 〜たい Like an い-Adjective

Here is something many beginners don’t realise: たい behaves exactly like an い-adjective. That means you can conjugate it into the negative, past, and past-negative just as you would with 高い（たかい）or 寒い（さむい）.

Example Sentences

Particle note: The direct object marker を is often softened to が when used with たい, especially in casual speech. Both 水を飲みたい and 水が飲みたい are natural; the が version emphasises the desire for that specific thing.

Yuka

Rei、夏休みにどこかに行きたい？
(Rei, do you want to go somewhere for summer break?)

Rei

うん！沖縄に行きたい！ビーチで泳ぎたいな。
(Yeah! I want to go to Okinawa! I want to swim on the beach.)

ほしい: Expressing Desire for an Object

While 〜たい attaches to verbs, ほしい attaches to nouns. It means “I want [a thing]” — a desire for a physical object, concept, or noun.

Formation: [Noun] + が + ほしい

Like たい, ほしい is an い-adjective and conjugates the same way: ほしくない (don’t want), ほしかった (wanted), ほしくなかった (didn’t want).

Softer phrasing: In real conversation — especially when making requests or expressing a need indirectly — ほしいのですが is much more natural than a blunt ほしい. The のですが softens the statement and implies “…so I was wondering if that’s possible.”

〜てほしい: Wanting Someone Else to Do Something

This is the pattern learners most often overlook — and it fills a gap that neither たい nor ほしい alone can cover. 〜てほしい means “I want [someone] to do [something].” It is built from the て-form of a verb plus ほしい, and the person you want to do the action is marked with に.

Formation: [Person] に + [Verb て-form] + ほしい

Formation note: The て-form of a verb is the base for many Japanese grammar patterns. For Group 1 (u-verbs), swap the final vowel sound: 書く → 書いて, 話す → 話して, 飲む → 飲んで. For Group 2 (ru-verbs), simply add て: 食べる → 食べて, 見る → 見て. The irregular verbs する → して and くる → きて.

Very polite version: In formal situations — a business email, a polite request to a superior — 〜ていただきたいのですが is the ultra-respectful equivalent. It uses いただく (the humble form of もらう) and means “I would humbly like you to…”

Yuka

Rei、このレポートを確認してほしいんだけど…
(Rei, I want you to check this report for me…)

Rei

いいよ。でも、もう少し早く言ってほしかったな。
(Sure. But I wanted you to tell me a bit sooner, you know.)

Comparison: たい vs ほしい vs 〜てほしい

Third-Person Desires: 〜たがる and ほしがる

Here is a rule that surprises many learners: in Japanese, you cannot use たい or ほしい to describe what someone else wants — at least not as a direct statement. This is because Japanese treats desires as internal feelings. Saying 彼は行きたい (“he wants to go”) sounds presumptuous, as if you can read someone else’s mind with certainty.

Instead, Japanese uses two alternative patterns for third-person desires:

Notice that ほしがる takes を (not が) as its object marker, unlike ほしい which takes が. This is because ほしがる is a verb, not an adjective.

When can you use たい for a third person? There are a few natural exceptions:

• Reported speech / quotation: 彼は日本に行きたいと言っていた。(He said he wants to go to Japan.) — because you’re quoting, not asserting from your own knowledge.
• Questions to the person directly: あなたはどこに行きたいですか。(where do you want to go?) — addressing the person in question.
• Story / narration perspective: Fiction or narration sometimes uses たい for a character because the narrator has access to their inner state.

Yuka

弟はずっと新しいゲームをほしがってるよ。誕生日プレゼントにしようかな。
(My little brother has been wanting a new game. Maybe I’ll make it his birthday present.)

Rei

いいね！あの子、毎日それを買いたがってたもんね。
(Nice! He’s been wanting to buy that thing every day, hasn’t he.)

Common Mistakes to Avoid

Even learners who know the patterns still make these errors. Recognising them now will save you embarrassment later.

Mistake 1: Using 〜たい with a noun

Wrong: 新しい自転車がたい。
Right: 新しい自転車がほしい。

たい only attaches to verb masu-stems. For nouns, you always use ほしい.

Mistake 2: Forgetting に with 〜てほしい

Wrong: 彼が来てほしい。
Right: 彼に来てほしい。

The person you want to do the action receives the particle に, not が. Using が here makes it sound like “I want him to come” in a subject-clause sense, which is unnatural and possibly ambiguous.

Mistake 3: Using 〜たい to describe someone else’s desires

Unnatural: 彼は日本に行きたいです。(as a direct statement about his inner feelings)
Natural: 彼は日本に行きたがっています。

Or add a quote particle: 彼は「日本に行きたい」と言っています。

Mistake 4: Treating ほしがる like ほしい (wrong particle)

Wrong: 子どもがおもちゃがほしがっている。
Right: 子どもがおもちゃをほしがっている。

ほしい (adjective) takes が, but ほしがる (verb) takes を. Switching them is a very common error.

Mistake 5: Using 〜てほしい to yourself

Wrong: 私に行ってほしい。(meaning “I want myself to go”)
Right: 私は行きたい。

〜てほしい is specifically for wanting someone else to act. For your own desires, use 〜たい.

Quick Quiz

Test your understanding. Choose the correct pattern or fill in the blank, then check the answers below.

Q1. You want to eat sushi. How do you say this in Japanese?
(a) 寿司がほしい。
(b) 寿司を食べたい。
(c) 寿司を食べてほしい。

Q2. You want a new bag. Which is correct?
(a) 新しいかばんを買いたい。
(b) 新しいかばんがほしい。
(c) Both are natural, but mean different things.

Q3. Fill in the blank: You want your friend to wait. → 友達___待ってほしい。
(a) が
(b) に
(c) は

Q4. Your sister seems to want a new phone. Which is correct?
(a) 姉は新しいスマホがほしい。
(b) 姉は新しいスマホをほしがっている。
(c) 姉は新しいスマホをほしい。

Q5. Which sentence means “I wanted the teacher to explain it”?
(a) 先生が説明したかった。
(b) 先生に説明してほしかった。
(c) 先生に説明したかった。

Answers

A1. (b) — 寿司を食べたい。Eating is an action you do, so 〜たい is correct. Option (a) ほしい would mean you want sushi as a possession, which is unusual phrasing. Option (c) would mean you want someone else to eat sushi.

A2. (c) — Both sentences are natural but different. 新しいかばんを買いたい means “I want to buy a new bag” (desire to perform the buying action). 新しいかばんがほしい means “I want a new bag” (desire to have the bag). Choose based on what you’re emphasising.

A3. (b) — に。The person you want to do the action is always marked with に in the 〜てほしい pattern. So: 友達に待ってほしい。

A4. (b) — 姉は新しいスマホをほしがっている。For third-person desires involving a noun, use ほしがる with the object particle を. Option (a) uses ほしい directly for a third person, which is unnatural. Option (c) has both the wrong verb form and the wrong particle.

A5. (b) — 先生に説明してほしかった。〜てほしい marks the person with に and uses the て-form. Option (a) means “the teacher wanted to explain,” and option (c) mixes the に particle with たかった (which expresses your own past desire to do something).

How did you do? If you got 4 or 5 right, you have a solid grasp of these patterns. If you found Q4 or Q5 tricky, revisit the sections on third-person desires and 〜てほしい above — those are the areas that take a little extra practice.
