I hope the year 2012 will bring you lots of happiness! And I would like to keep working on helping you all improve Japanese on this site, as well as on Twitter and Facebook!

OK, the first lesson of the year was requested by my FB friend, Nur !

He asked me how to use わけではない (= wake dewa nai)

Let’s get started!

The kanji for わけ(=wake) is . It means reason(s)

The literal meaning of わけではない (= wake dewa nai) is

:rrrr: “It is not the reason (why)”

We use it when we want to say


It doesn’t mean that., It’s not like 〜. , It’s not the case that 〜., I don’t mean that〜., That is not why 〜., That is not the reason 〜., It is not really 〜., not to do much〜., not necessarily, not altogether 〜., not particularly 〜.


I know, I know…there are many meanings. :) We’ll look at the usages one at a time.

:mm: How to form :

verb+ わけではない ( = wake de wa nai)

:rrrr: わけではありません ( =wake dewa arimasen.)

:i: Note : The casual form of わけではない(=wake dewa nai) is

:rrrr: わけじゃ(あ)ない(です) (=wakeja(a) nai (desu).)


わけじゃ(あ)ありません (= wakeja(a) arimasen)

!to right! じゃ(あ)(=ja(a)) is a casual contraction of では(=dewa)

(If you want to learn more, go check りゃあじゃあ (=ryaa& jaa) lesson! )



:w: Now let’s find out how and when to use these expresssions :

We use わけではない(= wakede wa nai) when we deny something “partially” but not “totally”.

!lotsofhearts! 1) It is not always true that 〜. / not altogether 〜. :

Ex. 先生がみんなすべての答えを知っているわけではない

= Sensei ga minna subete no kotae wo shitteiru wake dewa nai.

= Teachers don’t necessarily know all the answers./ It is not always true that all the teachers know the answers.

:u: (more formal)

〜 わけではないです。/ 〜 わけではありません。

= 〜 wake dewa nai desu. / 〜 wake de wa arimasen.

(You might think all the teachers know the answers for everything, but it is not true.)

Ex. マギーはいつも寝ているわけではない

= Maggie wa itsumo nete iru wake dewa nai.

= Maggie is not always sleeping.

(You might think I am always sleeping but) it is not true.

:u: (more formal)

マギーはいつも寝ているわけではないです。/ わけではありません。

= Maggie wa itsumo nete iru wakewake dewa nai desu / wake dewa arimasen

:u: (more casual)

マギーはいつも寝ているわけじゃ(あ)ない(です)。/ わけじゃ(あ)ありません。

= Maggie wa itsumo nete iru wake ja(a)nai (desu). / wakeja(a) arimasen.

Ex. 高い料理がすべて美味しい(という)わけではない

= Takai ryouri ga subete oishii (toiu) wake dewa nai

= All expensive dishes are not altogether delicious.

(You might think all the expensive food are delicious but) it is not true.

:u: (more formal)

高い料理がすべて美味しい(というわけではないです。/ わけではありません。

= Takai ryouri ga subete oishii (toiu) wake dewa naidesu / wake dewa arimasen

:u: (more casual)

高い料理がすべて美味しい(という)わけじゃ(あ)ない(です)/ わけじゃ(あ)ありません。

= Takai ryouri ga subete oishii (toiu) wakeja(a) nai (desu) / wake ja(a) arimasen.

!lotsofhearts! 2) When you deny some expected reason subtly.

It is not because of that,

Ex. 「日本語もうあきらめたの?」

= Nihongo mou akirameta no?

= Have you given up Japanese already?

:rrrr: 「そういうわけじゃないよ。」(male speech)

= Souiu wake ja nai yo.

= That is not the case./ That’s not true.

:rrrr: 「そういうわけじゃないの。」(female speech)

= Souiu wake ja nai no.

= That is not the case./ That’s not true.


Ex. 彼があの人と別れてしまったのはマギーが悪いわけではないから心配しないで!

= Kare ga anohito to wakarete shimatta nowa Maggie ga warui wake dewa nai kara shinpai shinai de!

= He didn’t break up with that person because of you , Maggie. So don’t worry about it.

!lotsofhearts!3) When you want to explain a reason subtly : It is not like~


= Kare wo youshi dake de eranda wake dewa nai.

It is not like I chose him for his appearance.

Ex. マギーのことが嫌いになったわけではないよ

= Maggie no koto ga kirai ni natta wake dewa nai yo.

= It is not like I came to dislike you, Maggie.

:rrrr: :maggie-small: Maggie’s note : Ugh! This is a cliché line that I often get. It’s a perfect phrase (but lame excuse) used to break up with people.

!star! Let’s compare the following two sentences:

1) ABではない

=A wa B dewa nai


2) ABというわけではない

= A wa B toiu wake de wa nai

While 1) means “A is not B” 2) means “A is not necessary B.”/”I wouldn’t say A is totally B” and it doesn’t deny anything completely.

Therefore it sounds more subtle or vague.


Ex. 結婚するなら絶対にお金持ちというわけではない

= It is not necessarily true that I would only marry a rich man.

Ex. 彼はチャラ男というわけではないが言うことに重みがない。

Now, some of you are ready to write this question in the comment section.

!to right! Q .マギー先生、 I also heard わけがない (= wake ga nai).  Are they different?


Yes, わけではない (= wake dewa nai) and わけがない(= wake ga nai) are different.



わけがない(= wake ga nai) is used when you totally deny something.


It means There is NO WAY that 〜, it is impossible that 〜, can’t be

Some of you might know the title of a very popular comic book (animation) called,
