Kurai and Gurai in Japanese: About, So Much That, and At Least

Kurai and gurai look like one small word for about, but in conversation they also exaggerate, belittle and scold, sometimes all in the same afternoon.

Kurai and Gurai in Japanese: About, So Much That, and At Least

Kurai and its voiced twin gurai are the same particle, and most of the time you can use either. Their first job is approximation: go-fun gurai, about five minutes, or dono kurai, how much. Their second is extent, describing how far something goes with a comparison, as in shinu kurai isogashii, so busy I could die. Their third is minimising: sore kurai means just that much, and it turns up in reassurance, in modest offers, and in mild scolding such as denwa kurai shite yo, at least call me. This guide shows each use with formation tables and everyday phrases, explains when people lean towards kurai or gurai, and compares them with hodo and goro, the two words learners most often confuse them with.

Kurai and gurai are interchangeable in almost every sentence

With amounts and durations they mean about; with time points, goro is standard

With a verb or adjective clause they describe extent: so much that

Sore kurai and X kurai wa mean at least or no more than, often with a scolding tone

Three jobs for one particle

Kurai comes from a word meaning rank or level, and every use still carries that idea: it marks a level on a scale. With a number, the level is a rough amount. With a clause, the level is how far something goes. With sore or a noun plus wa, the level is set deliberately low, which gives the sense of at least or only that much.

Once you see the scale, the three uses stop feeling unrelated. Here they are side by side before we look at each in detail.

UsePatternExampleMeaning
Approximationnumber or amount + ぐらい十分ぐらい待ちました。I waited about ten minutes.
Extentclause + くらい泣きたいくらいうれしい。I'm so happy I could cry.
Minimumそれくらい or noun + くらい電話くらいしてよ。At least give me a call.

About and around: approximate amounts

The most common use is attaching gurai or kurai to a number, a duration, a price or a distance to mean about or roughly. It softens precise numbers and is very natural when you are estimating. In questions, dono kurai and dore kurai ask how much or how long.

It also follows kore, sore and are, giving about this much. With a gesture, kore gurai is how people show sizes with their hands.

JapaneseRomajiMeaning
駅まで歩いて十分ぐらいです。Eki made aruite juppun gurai desu.It's about ten minutes' walk to the station.
どのくらいかかりますか。Dono kurai kakarimasu ka.How long does it take?
日本に来て一年ぐらいになります。Nihon ni kite ichinen gurai ni narimasu.It's been about a year since I came to Japan.
三千円ぐらいのお土産を探しています。Sanzen-en gurai no omiyage o sagashite imasu.I'm looking for a souvenir for around three thousand yen.

二十人ぐらい来ると思います。Nijūnin gurai kuru to omoimasu.I think about twenty people will come.
どれくらい日本語を勉強していますか。Dore kurai nihongo o benkyō shite imasu ka.How long have you been studying Japanese?

Gurai versus goro for time

English uses about for both a length of time and a point in time. Japanese standard usage splits them. Goro attaches to points: clock times, dates and periods such as the end of the month. Gurai attaches to durations and amounts. In casual speech, many people also say sanji gurai for about three o'clock, and you will hear it often, but goro is the safer choice in polite speech.

Goro can take ni, as in sanji goro ni, or drop it, as in sanji goro. Both are common. In casual speech you will also hear sanji gurai ni, but in careful speech keep gurai for amounts and goro for times.

JapaneseRomajiMeaning
七時ごろに着きます。Shichiji goro ni tsukimasu.I'll arrive around seven.
二時間ぐらい遅れるそうです。Nijikan gurai okureru sō desu.Apparently it will be about two hours late.
何時ごろがいいですか。Nanji goro ga ii desu ka.Around what time suits you?

For about two weeks二週間ぐらい二週間くらい二週間ごろ
About what time?何時ごろ何時ぐらい何時間ごろ
About how long?どのくらいどれぐらいどのごろ

So much that: describing extent

Attach kurai to a plain-form clause and it describes how far a state goes, measured by a comparison: so tired I could fall asleep standing, so delicious I could not stop. The clause is usually an exaggeration or a vivid image, and the adjective or verb that follows is the real point.

Kurai no before a noun works the same way: odoroku kurai no nedan, a price that makes you gasp. People use this constantly in reviews, stories and complaints.

JapaneseRomajiMeaning
顔が赤くなるくらい恥ずかしかった。Kao ga akaku naru kurai hazukashikatta.I was so embarrassed my face went red.
毎日食べたいくらい好きです。Mainichi tabetai kurai suki desu.I love it so much I could eat it every day.

信じられないくらい安い信じられないくらい安い。Unbelievably cheap
立っていられないくらい疲れた立っていられないくらい疲れた。So tired I could barely stand
びっくりするくらいのびっくりするくらいの人だった。There was a startling number of people

At least and only that much: sore kurai

The third use sets the level low on purpose. Sore kurai, kore kurai and noun + kurai mean just that much, and the tone depends on who the task belongs to. About your own trouble, it is modest reassurance: kore kurai daijōbu, this much is nothing. About someone else's duty, it becomes at least or even: aisatsu kurai shinasai, at least say hello.

In requests the minimum use can be gently scolding, which is why it appears so often between family members and close friends. With people above you, avoid using it about their actions.

JapaneseRomajiMeaning
これくらい大丈夫ですよ。Kore kurai daijōbu desu yo.This much is no trouble at all.
それくらい自分でやって。Sore kurai jibun de yatte.Do that much yourself, at least.
遅れるなら、連絡くらいしてよ。Okureru nara, renraku kurai shite yo.If you're going to be late, at least let me know.
挨拶ぐらいしなさい。Aisatsu gurai shinasai.Say hello, at least.
お茶くらい飲んでいってください。O-cha kurai nonde itte kudasai.At least stay for a cup of tea.
簡単な料理くらいなら作れます。Kantan na ryōri kurai nara tsukuremasu.I can manage simple dishes, at least.

Kurai nara: rather than going that far

Clause + kurai nara sets up something undesirable and then says what would be better. It often ends with hō ga ii or hō ga mashi, it is better or it is less bad. The English is if you are going to do that, you might as well, or rather than that.

It is a strong, opinionated pattern, so it suits casual conversation and advice between friends more than polite requests.

JapaneseRomajiMeaning
途中でやめるくらいなら、最初からやらないほうがいい。Tochū de yameru kurai nara, saisho kara yaranai hō ga ii.If you're going to quit halfway, better not to start.
並ぶくらいなら、別の店に行こう。Narabu kurai nara, betsu no mise ni ikō.Rather than queue, let's go somewhere else.
タクシーに乗るくらいなら歩きます。Takushī ni noru kurai nara arukimasu.I'd rather walk than take a taxi.

Kurai versus hodo

Hodo overlaps with kurai in the extent use: shinu hodo isogashii and shinu kurai isogashii both work, with hodo sounding a touch stronger and more written. The two part ways elsewhere. Hodo is required in negative comparisons such as kyonen hodo samuku nai, not as cold as last year, and it appears in the more, the more pattern covered in the ba hodo guide. Kurai is the one for minimising, as in sore kurai.

Both appear in X kurai or X hodo ... wa nai, meaning there is nothing as ... as X. In speech, kurai is slightly more common here.

MeaningKuraiHodoNote
About ten people十人ぐらい十人ほどHodo sounds polite or formal
So busy I could die死ぬくらい忙しい死ぬほど忙しいBoth natural
Not as cold as last yearNot natural去年ほど寒くないUse hodo
Nobody is as kind as him彼くらい優しい人はいない彼ほど優しい人はいないBoth natural
At least do that muchそれくらいやってNot used this wayUse kurai

Jūnin hodo, about ten people, is a common polite way to give an approximate number in business and announcements. In a shop or at work, go-fun hodo o-machi kudasai, please wait about five minutes, is standard staff Japanese.

Common mistakes to avoid

  • Using goro for durations: say sanjikan gurai, not sanjikan goro.
  • Using kurai in a negative comparison: kyonen hodo samuku nai, not kyonen kurai samuku nai.
  • Attaching kurai to a na-adjective stem: say shizuka na kurai, not shizuka kurai, when you mean to the extent it is quiet.
  • Using sore kurai about a superior's work: it minimises their effort and can sound dismissive.
  • Forgetting no before a noun: sanzen-en gurai no omiyage, not sanzen-en gurai omiyage.
  • Worrying about kurai or gurai: pick one and keep going; both are correct in almost every case.
Key points

A practical way to improve

Describe your day out loud with a gurai on every amount: how long you slept, how far you walked, how much coffee you drank. Then exaggerate three feelings with a kurai clause, such as naki-tai kurai, and add one sore kurai reassurance. Finally, ask your AI Sensei in Unihongo's immersive 3D classroom to run the Catch the Right Train mission and ask how long each journey takes with dono kurai kakarimasu ka, answering back with approximate times.

FAQ

Frequently asked questions

Is there any difference between kurai and gurai?

In meaning, no. Many speakers use gurai more often after numbers and nouns and kurai after verbs and adjectives, and some feel kurai is slightly more careful, but both are correct in nearly all cases and you will hear each one everywhere.

Can I say sanji gurai for about three o'clock?

In casual speech you will hear it often, and most people accept it. The standard choice for a point in time is goro: sanji goro. For a duration, only gurai works: sanjikan gurai, about three hours.

What is the difference between shinu kurai and shinu hodo?

Both mean so much that I could die and both are common. Hodo sounds slightly stronger and a little more written; kurai is more conversational. In most everyday exaggerations you can swap them freely.

Why does sore kurai sometimes sound rude?

Because it minimises. Sore kurai jibun de yatte means do at least that much yourself, implying the task is trivial. Used about your own effort, as in kore kurai daijōbu desu, it is a modest reassurance instead.

Can kurai be used in negative comparisons like not as cold as?

Not naturally. Not as cold as last year is kyonen hodo samuku nai, with hodo. Kurai appears in the positive pattern kare kurai yasashii hito wa inai, there is nobody as kind as him.
