Japanese doesn’t just use one alphabet like English does. It actually uses three different writing systems, often in the exact same sentence.

As a Japanese teacher, I always tell my students: the Japanese writing system is incredibly logical.

It makes perfect sense once you know how it works.

In this guide, I’ll explain exactly what these three systems are, how they work together, and why you need them.

What are the three Japanese writing systems?

The Japanese writing system is made up of three separate scripts:

• Hiragana: Curvy characters used for native Japanese words and grammar.
• Katakana: Sharp, angular characters used for foreign loanwords and emphasis.
• Kanji: Complex characters borrowed from Chinese that represent whole words or meanings.

You’ll also sometimes see romaji, which is simply Japanese written using English letters (like writing sushi instead of すし). However, romaji is mostly used for beginners or for typing on a keyboard.

Let’s look at each of the three main systems in detail.

Hiragana: the foundation of Japanese

Hiragana is the most important writing system for beginners. It’s the very first thing Japanese children learn in school, and it should be the very first thing you learn, too.

There are 46 basic hiragana characters.

Unlike English letters, which can make different sounds depending on the word (like the “a” in apple vs. father), every hiragana character always makes the exact same sound. They’re phonetic, meaning they represent syllables rather than meanings.

Hiragana is very curvy and flowing. We use it for native Japanese words, verb endings, and grammar particles (the little words that connect a sentence together).

Here’s a look at the five basic vowels in Japanese:

When you write simple, everyday greetings, they’re usually written entirely in hiragana:

Katakana: for foreign words and emphasis

Katakana also has 46 basic characters. In fact, katakana makes the exact same sounds as hiragana.

So, why do we need a second set of characters for the same sounds?

Think of katakana like italics in English. It stands out. Katakana is noticeably sharper and more blocky than hiragana.

We use katakana mainly for:

• Foreign loanwords: Words borrowed from other languages, especially English.
• Foreign names: If your name is John or Sarah, you’ll write it in katakana.
• Emphasis: Like writing in ALL CAPS to make a word pop.
• Scientific terms: Animal and plant names are often written in katakana.

Here’s how the five vowels look in katakana compared to hiragana:

And here are some examples of English words that were borrowed into Japanese, written in katakana:

Kanji: the meaning blocks

This is often the most fascinating part for learners!

Kanji are characters that were brought over to Japan from China thousands of years ago. Unlike hiragana and katakana (which just represent sounds), kanji represent meanings.

Think of them like emojis. When you see a 🌲 emoji, you instantly know it means “tree”, regardless of how you pronounce it. Kanji works the exact same way.

For example:

• 木 means “tree”
• 林 means “woods” (two trees together)
• 森 means “forest” (three trees together)

There are thousands of kanji, but you only need to know about 2,000 to read a Japanese newspaper.

A quick note on regional variations:

While kanji originally came from China, Japan eventually created some of its own characters called kokuji (national characters). For example, 働 (to work) is a kanji made entirely in Japan. Additionally, depending on the region of Japan you visit, you might see rare, hyper-local kanji used for specific fish types, local crops, or regional city names that aren’t used in standard Tokyo Japanese!

How they work together in a sentence

You might be wondering, why use all three at the same time?

Using all three systems actually makes Japanese much easier to read. Because Japanese doesn’t use spaces between words, mixing these three scripts helps your brain instantly see where words begin and end.

Let’s look at a simple sentence: “I eat bread.”

Here’s how the three writing systems are working together in this one sentence:

• 私 (watashi): Kanji. It carries the core meaning of “I” or “me”.
• は (wa): Hiragana. This is a grammar particle showing that “I” is the topic.
• パン (pan): Katakana. This means “bread”. It’s a foreign loanword originally borrowed from Portuguese!
• を (o): Hiragana. Another grammar particle connecting the bread to the verb.
• 食 (ta): Kanji. The core meaning of “eat”.
• べます (bemasu): Hiragana. The grammatical ending that makes the verb polite.

Kanji gives you the heavy meanings (I, eat). Katakana points out the foreign word (bread). Hiragana glues it all together with grammar (wa, o, bemasu).

Why not just use English letters (romaji)?

A lot of beginners ask me, “Can I just learn Japanese using English letters?”

The short answer is: No, you shouldn’t.

Using romaji is fine for your first week, but if you rely on it, you’ll hit a massive brick wall later on. Japanese has a huge amount of homophones (words that sound exactly the same but mean different things).

For example, the sound “hashi” can mean:

• 橋 (Bridge)
• 箸 (Chopsticks)
• 端 (Edge)

If you only read in English letters, you won’t know which hashi the sentence is talking about. Kanji makes the meaning instantly clear. Furthermore, almost no authentic Japanese material (books, menus, signs) uses romaji. To truly learn the language, you must learn the scripts.

The Japanese writing system is a beautiful, highly functional combination of three scripts.

• Use hiragana for grammar and native words.
• Use katakana for foreign words.
• Use kanji for the core meanings of words.
