The Japanese Alphabet: Hiragana, Katakana and Kanji Explained

Japanese has no alphabet. It has three writing systems, and all three appear in the same sentence.

That sounds like a disaster, and it is the reason Japanese has a reputation for being brutal. But it is less arbitrary than it looks: each of the three has a clear job, and once you see the division of labour, the confusion disappears.

What remains is work. But sorted work.

The three at a glance

A real sentence:

私はイギリスから来ました (watashi wa igirisu kara kimashita, "I come from England")

In there: 私 and 来 are kanji. イギリス is katakana (because "England" is a foreign word). は, から, ました are hiragana (grammar).

See the pattern? Kanji carries the meaning, hiragana glues it together, katakana marks the foreign. That is the whole logic.

Why three? The short history

Japan had no writing and imported Chinese characters in the 5th century. Problem: Chinese and Japanese are grammatically opposite. Chinese has no endings; Japanese is made of endings.

So they kept kanji for the meanings and invented two syllabaries for the rest. Hiragana came from simplified kanji and was long considered the "women's script". Katakana came from fragments of kanji, used by Buddhist monks.

The result grew historically rather than being designed: the exact opposite of Korean hangul, which one person deliberately engineered in 1443 as a learnable system. That historical layering is why a practical Japanese learning approach must treat reading and speaking as separate jobs at first.

The order

This is the question that matters, and the answer is not up for debate:

1. Hiragana first. No discussion. Without hiragana you cannot read a Japanese sentence, because all the grammar is written in it. Realistically: one week at 20 minutes a day.

2. Katakana next. Same system, different shapes. Another week. The payoff is immediate: katakana words are often borrowed from English, so you understand them for free.

3. Kanji in parallel, forever. Not in a block. Kanji is learned in words, over years, and you are never finished. Neither are Japanese people.

Not: rōmaji. The Latin transcription is a dead end. It is comfortable, it keeps you reading aloud, and it ensures you never touch real material. Two weeks of kana costs less than a year of rōmaji dependency.

Hiragana: the full table

The system: consonant + vowel, in five vowel columns. Know the five vowels and you know the structure.

The exceptions matter: し is shi, ち is chi, つ is tsu, ふ is fu. Not typos: those sounds simply do not exist otherwise in Japanese.

Two strokes make a sound voiced:

Katakana: same table, different shapes

Katakana is phonetically identical to hiragana. The same 46 syllables, different characters. It only marks that a word came from outside.

イギリス▶ is a nice one for English speakers: it comes from "Inglez", the Portuguese for English, because the Portuguese got to Japan first. Japanese borrowed from Portuguese in the 16th century, Dutch in the 17th, German for medicine, and English for everything since.

The stroke ー lengthens the vowel. コーヒー is ko-o-hi-i, not kohi. Vowel length distinguishes meanings in Japanese: that is not a detail.

Kanji: the honest part

Here is the truth that friendly articles leave out: kanji is a lot of work, and it never ends.

About 2,000 characters count as the daily minimum (the jōyō kanji). Japanese schoolchildren take nine school years.

And worse: each kanji has multiple readings. 人 (person) is hito alone, but jin in 日本人 (nihonjin, Japanese person) and nin in 三人 (sannin, three people). Which one applies depends on the word.

That is why the only strategy that works is: never learn kanji in isolation, always in words. A character on a flashcard is nearly worthless, because you cannot guess the reading. A word gives you reading, meaning and usage at once.

One relief: small hiragana are often printed above rare kanji to give the reading. That is called furigana, and in learner material and manga it is everywhere.

The good news

After all that: Japanese sounds easy.

Five vowels that always sound the same. No tones like Chinese. Not one sound an English mouth cannot make. Nothing you have to consciously construct, unlike the Arabic ع or the Korean ㅓ.

In fact, English has around twenty vowel sounds and Japanese has five. You do not need to learn new sounds; you need to stop diphthongising. English turns o into ou and e into ei almost automatically. Japanese vowels are short, pure and flat.

The difficulty of Japanese is entirely in the writing and the grammar, not the sound. Which means something concrete: you can start speaking early, long before you can read. And you should.

That is exactly why the usual order is backwards. People wait until they know 500 kanji and have not said a sentence in two years.

How to approach this

1. Two weeks of kana. 20 minutes a day, writing and reading aloud. After that, never rōmaji again.
2. In parallel, speak. Do not wait for the writing. Hear sentences and repeat them out loud, right behind the audio: that is shadowing. Watch the rhythm: Japanese counts syllables of equal length, and English stress rhythm sounds immediately wrong.
3. Kanji in words, never alone. And with spaced repetition, because 2,000 characters do not stay without a system.
4. Your sentences first. Not the textbook's. Those are your language islands.

That is what the Hyperpolyglot app is built for: you write the phrases your life actually needs, they come back in a native voice, and you loop them out loud, completely independent of where you are with the kanji. Available on iOS, Android, and Web.

Common Mistakes to Avoid

1. Staying on rōmaji. The dead end. Two weeks of kana saves you a year of dependency.
2. Kanji before hiragana. No hiragana, no sentence. The order is not negotiable.
3. Learning kanji as lone flashcards. Without a word, there is no reading.
4. Ignoring vowel length. おばさん▶ (aunt) and おばあさん▶ (grandmother) are not the same word.
5. Waiting until you can read to speak. The sound is the easy part. Start there.
6. Diphthongising the vowels. Japanese has five, English has twenty. You need to remove, not learn.
7. Thinking all three scripts weigh the same. Hiragana is compulsory, katakana is quick, kanji is a life project.
