How to Say Want in Japanese with Hoshii and Tai

欲しい Hoshii and 〜たい ~tai are the two workhorse ways to say “want” in Japanese. One is for things you want. The other is for actions you want to do. Tiny difference, huge payoff. Japanese grammar loves this kind of neat little trap.

If you mix them up at first, congratulations: you are learning Japanese like a normal human being. Even learners who study hard usually bump into this pair early, because English uses one lazy word, “want,” and Japanese does not feel like being that generous.

For a bigger picture of Japanese learning, this lesson fits neatly into the rest of the basics on Learn Japanese.

The basic idea is simple:

• 欲しい Hoshii = want a thing
• 〜たい ~tai = want to do an action

How 欲しい Works

欲しい Hoshii means “want” when you want a noun: a phone, a bag, coffee, time, peace, a new life, that sort of thing. You use it with が ga, not を o.

Rule: Noun + が ga + 欲しい hoshii

Notice the pattern. It is not 水を欲しい. Japanese does not care about your English instincts. Use が ga.

How 〜たい Works

〜たい ~tai means “want to do.” It attaches to the stem of a verb. This is the form you use when you want to eat, go, see, buy, sleep, or escape your inbox.

Rule: Verb stem + たい tai

Yes, the object marker here is usually を o. Because now you are wanting an action, not a thing. Japanese likes being precise in the least convenient possible way.

Useful Phrases You Will Actually Use

Polite And Casual Ways To Say It

〜たい ~tai is often used in casual speech. For polite speech, you usually add です desu.

Small warning: 欲しいです hoshii desu is polite, but it still means “I want.” If you want to sound even softer, Japanese often uses expressions like 〜たいと思います ~tai to omoimasu.

Soft And Natural Variants

〜たがる ~tagaru is for observing other people’s desire. You do not usually use たい tai to directly describe someone else’s desire unless it is your own quote, guess, or a very casual close situation. Humans are private. Japanese grammar agrees.

Common Confusion: 欲しい Versus 〜たい

欲しい Hoshii wants a noun. 〜たい ~tai wants a verb. That is the whole trick. The rest is just practice, repetition, and the occasional grammar faceplant.

Practice: Choose The Right Form

Pick 欲しい hoshii or 〜たい ~tai. Then check the answer below each line.

• コーヒーが＿＿＿。 Kōhī ga _____. — I want coffee.
• Answer: 欲しい hoshii
• コーヒーを飲み＿＿＿。 Kōhī o nomi_____. — I want to drink coffee.
• Answer: たい tai
• 友達が＿＿＿。 Tomodachi ga _____. — I want a friend. / I want friends.
• Answer: 欲しい hoshii
• 友達に会い＿＿＿。 Tomodachi ni ai_____. — I want to meet my friend.
• Answer: たい tai
• 新しい本が＿＿＿。 Atarashii hon ga _____. — I want a new book.
• Answer: 欲しい hoshii
• 本を読み＿＿＿。 Hon o yomi_____. — I want to read a book.
• Answer: たい tai

Now the fun part: make your own sentences with the same pattern. If you can swap nouns and verbs correctly, the grammar is already starting to behave.

Common Mistakes And Fixes

One more useful note: if you want to say “I want to go to the store,” the verb is still the action, so it becomes 店に行きたい mise ni ikitai. The destination gets に ni, and the wanting stays with the verb.

Quick Reference Summary

• 欲しい Hoshii = want a thing
• 〜たい ~tai = want to do something
• 欲しい uses が ga
• 〜たい attaches to the verb stem
• 〜たいです is polite
• 〜たがる is used for someone else’s visible desire

If you remember only one thing, remember this: things use 欲しい, and actions use 〜たい. Clean, simple, and just annoying enough to stay in your memory forever.
