Japanese Grammar

Saying 'Because': から and ので

To give a reason for something, Japanese has two main words: kara (から) and node (ので). They both mean 'because', but they are used in very different situations.

Subjective vs Objective Reasons

から (kara) is subjective. It emphasizes your personal reason, opinion, or decision. It is direct and can sometimes sound a bit strong or selfish if used as an excuse.

ので (node) is objective. It presents the reason as a natural, unavoidable fact. Because it sounds less personal, it is considered softer, more polite, and is preferred in business or when making excuses.

How to connect them

Using から (kara)

Verbs / I-Adjectives

→Plain Form + から

E.g., 食べるから (taberu kara - because I eat)

Nouns / Na-Adjectives

→Add だ (da) + から

E.g., 好きだから (suki da kara - because I like it)

Polite speech

→Masu/Desu + から

You can attach kara directly to polite forms (e.g., 食べますから)

Using ので (node)

Verbs / I-Adjectives

→Plain Form + ので

E.g., 食べるので (taberu node - because I eat)

Nouns / Na-Adjectives

→Add な (na) + ので

IMPORTANT: Da changes to Na! E.g., 好きなのです -> 好きなので

Polite speech

→DO NOT use Masu/Desu + ので

Node usually attaches ONLY to plain forms, even in polite sentences.

Comparing the Nuance

時間がありませんから、行きません。

Jikan ga arimasen kara, ikimasen.

I don't have time, so I'm not going. (Direct, personal decision)

時間がないので、行けません。

Jikan ga nai node, ikemasen.

Because there is no time, I cannot go. (Objective fact, sounds like a polite excuse)

雨だから、タクシーに乗ろう。

Ame da kara, takushii ni norou.

It's raining, so let's take a taxi. (Noun + da kara)

雨なので、遅れました。

Ame na node, okuremashita.

Because of the rain, I was late. (Noun + na node - apologizing)

Teacher's Advice

Making Excuses

If you are apologizing to your boss for being late, NEVER use 'kara'. 'Densha ga okureta kara...' sounds like 'The train was late, so it's not my fault!'. Instead, use 'node': 'Densha ga okureta node...' This sounds like 'Due to the objective fact of the train delay, I am unfortunately late.'
