How to Use だから (dakara) – “So” / “That’s Why” in Japanese

Ever wanted to explain why something happened? Or connect your ideas with a simple "so" or "that's why"?

In Japanese, that's where だから (dakara) comes in. It's one of the easiest and most common ways to show cause and effect.

What Does だから Mean?

だから means “so” or “therefore.”
It connects two sentences, where the second one is a logical result of the first.

It’s casual, but polite enough for most everyday situations.

Example:

きのうはあめでした。だから、でかけませんでした。
Kinou wa ame deshita. Dakara, dekakemasen deshita.
It rained yesterday. So, I didn’t go out.

How to Use だから Correctly

✅ Use it between two full sentences

It starts the second sentence — don’t use it in the middle!

Correct:

ねむい。だから、コーヒをのむ。
I’m sleepy. So, I’m going to drink coffee.

Incorrect:

ねむいだからコーヒをのむ。 ← Sounds weird & grammatically incorrect ❌

🤔 What If You Want to Say It in One Sentence?

When you want to express "because" mid-sentence (not at the start), use 〜から instead of だから.

Example:

あつい。だから、うみにいきたい。
It’s hot. So, I want to go to the beach. ✅

あついから、うみにいきたい。
Because it’s hot, I want to go to the beach. ✅

The second version flows more smoothly and feels more natural in Japanese because there's no extra pause in between the two things you're saying.

How to Conjugate with ～から or だから

Depending on what comes before から, the form changes slightly:

1. Nouns and な-adjectives → Add だ + から

にちようび → にちようびだから
(It's Sunday, so…)
しずか（な）→しずかだから
(It’s quiet, so…)

Why? Because you need the だ to finish the noun/な-adjective phrase before attaching から.

2. い-adjectives and Verbs → Just add から

あつい (adjective) → あついから
つかれた (verb) → つかれたから
はやくおきた (verb, past tense) → はやくおきたから

These forms connect directly with から, no extra だ needed.

🥤 Just for Fun: Did You Know There’s a Drink Called だから?

So Suntory once made a drink called 「ダカラ」, marketed as a healthy lifestyle beverage full of vitamins.

Their slogan was:

からだにいい、だから、ダカラ。
(It’s good for your body — so, Dakara.)

You might still spot “Green DAKARA” in vending machines and conbinis in Japan. Try it next time. It's not bad, kind of tastes like Pocari Sweat) 😄

Everyday Examples

Let’s look at a few real examples of だから and 〜から in use:

にちようびだから、がっこうはありません。
It’s Sunday, so there’s no school.
👉 Here, we use だから because "にちようび" is a noun.
おなかがすいたから、ラーメンをたべます。
I’m hungry, so I’ll eat ramen.
👉 The verb "すいた" connects directly with から.
しずかだから、ここがすき。
It’s quiet, so I like it.
