First Words of Japanese Babies: What Do They Say and Why?

Have you ever wondered what the first words are for babies in Japan? Just like in many cultures, Japanese babies start with simple, easy-to-pronounce words. But the words they choose often reflect unique aspects of Japanese language and culture.

In this post, we'll explore the common first words Japanese babies say and dive into what makes them special. Whether you’re learning Japanese or just curious about the language, you’ll find these first words both adorable and fascinating!

1. ママ (Mama) – Mom

Just like in many other languages, "Mama" is often one of the first words Japanese babies say. The soft “ma” sound is easy for babies to pronounce, making it a universal word for calling mom.

In Japan, some children might later switch to more formal words like "お母さん (Okaasan)", but "Mama" remains a sweet and affectionate term throughout childhood.

2. パパ (Papa) – Dad

Similarly, "Papa" is a common first word when babies refer to their dads. The simple, repetitive syllables are easy to say, and just like "Mama", it's widely used in Japan.

As kids grow older, they might start using "お父さん (Otousan)" for "Dad," but "Papa" stays as a familiar and loving nickname in many families.

3. ワンワン (Wan-wan) – Woof woof (Dog)

Japanese babies love animals, and "ワンワン (Wan-wan)" is how they refer to dogs. This is an example of onomatopoeia—words that imitate sounds, which are very common in Japanese.

In English, babies might say "woof woof" or "doggy," but in Japan, animal sounds are often used as the actual words for animals, especially by young children. Other examples include:

• "ニャーニャー (Nyaa-nyaa)" for cats (meow)
• "モーモー (Moo-moo)" for cows (moo)
• "コケコッコー (Kokekokkoo)" for roosters (cock-a-doodle-doo)

4. ブーブー (Buu-buu) – Car / Honk honk

When talking about cars, Japanese babies often say "ブーブー (Buu-buu)" to mimic the sound of a car engine or horn. This playful onomatopoeia is an easy way for babies to recognize and refer to cars.

You might hear parents say:

• "ブーブーに乗る？" (*Buu-buu ni noru?* – Do you want to ride in the car?)
• "ブーブー来たよ！" (*Buu-buu kita yo!* – The car is here!)

5. バイバイ (Bai-bai) – Bye-bye

Interestingly, many Japanese babies learn "バイバイ (Bai-bai)" early on. This comes directly from the English "bye-bye" and is commonly used in Japan when saying goodbye. It's a simple, cheerful phrase that kids love to say while waving their hands.

Even as children grow older, "バイバイ" remains a casual and friendly way to say goodbye, alongside more formal farewells like "さようなら (Sayounara)".

Why Are These Words Special?

In Japanese, many of the first words babies say are simple, repetitive sounds that are easy to pronounce. But what makes Japanese unique is the rich use of onomatopoeia—words that mimic sounds. From animal noises to everyday objects like cars, these playful words are deeply embedded in Japanese language and culture.

Compared to other languages, Japanese first words often include sounds that reflect the world around the baby, making language learning both fun and interactive from the very beginning.
