Learn Japanese Causative Verbs Through Cooking

Natural Japanese Notes | Real Lesson

A Mexican Recipe Turned Into a Japanese Grammar Lesson!

In a recent Japanese lesson, my student was explaining how to prepare a Mexican pork dish.

We were talking about how the flavor goes into the meat.

That conversation led us to an interesting Japanese expression:

豚ぶた肉にくに味あじを染しみ込こませる。

To let the flavor soak into the pork.

But wait…

染しみ込こませる？ Why not 染しみ込こむ?

Let’s explore the difference!

---

1. 染み込む — To Soak In

染しみ込こむ

to soak in / to penetrate

染み込む is an intransitive verb

(自じ動どう詞し).

It describes something, such as a liquid or flavor, soaking into another substance.

For example:

豚ぶた肉にくに味あじが染しみ込こみます。

Let’s look at the particles:

• 豚肉に — into the pork
• 味が — the flavor (subject)
• 染み込みます — soaks in

The flavor soaks into the pork.

The sentence describes what happens naturally to the flavor.

Another example:

スープの味あじが野や菜さいに染しみ込こみます。

The flavor of the soup soaks into the vegetables.

2. 染み込ませる — To Make Something Soak In

染しみ込こませる

to cause something to soak in / to let the flavor soak in

Now imagine you’re cooking.

You prepare the meat and let the seasoning soak into it.

You can say:

豚ぶた肉にくに味あじを染しみ込こませます。

I let the flavor soak into the pork.

Here, 染み込ませる is the causative form

(使し役えき形けい) of 染み込む.

How does the verb change?

染み込む → 染み込ませる

しみこむ → しみこませる

染み込む is a Group 1 (Godan) verb.

To make its causative form:

む → ませる

The causative form can express causing something to happen.

In cooking, this is often used to describe intentionally letting a liquid or flavor soak into an ingredient.

3. Notice the Particles!

Compare these two sentences:

① 染み込む

豚ぶた肉にくに味あじが染しみ込こみます。

The flavor soaks into the pork.

② 染み込ませる

豚ぶた肉にくに味あじを染しみ込こませます。

I let the flavor soak into the pork.

Notice the difference:

味が → 味を

With 染み込む, the flavor is the subject of the sentence.

With 染み込ませる, someone causes the flavor to soak into the meat. The flavor becomes the object, marked by を.

But 豚肉に stays the same because it tells us where the flavor goes.

4. Isn’t the Causative Form About Making People Do Things?

Many Japanese learners first study causative sentences like:

母ははは子こどもに野や菜さいを食たべさせます。

The mother makes her child eat vegetables.

Here, one person causes another person to do something.

But Japanese causative forms can also describe causing a change or an event.

For example:

味あじを染しみ込こませる。

To cause the flavor to soak in.

No person is being forced to do anything!

This is why cooking is a great way to discover another use of the causative form.

6. Your Turn: Describe Your Own Cooking!

Think of a dish you enjoy making.

Can you use one of these expressions?

味あじが染しみ込こむ

The flavor soaks in.

味あじを染しみ込こませる

To let the flavor soak in.

For example:

肉にくに味あじをよく染しみ込こませます。

I let the flavor soak thoroughly into the meat.

Try explaining one step of a recipe in Japanese.

You don’t need to make a complicated sentence. Start with one natural expression!

Small Conversations, Big Discoveries

What began as a conversation about Mexican cooking became a chance to explore Japanese verb forms and particles.

These are the moments I enjoy in Japanese lessons.

We can learn grammar through real conversations, everyday experiences, and topics that matter to each student.
