How Japanese Writing Works

How Japanese Writing Works

Japanese has one of the most fascinating writing systems in the world. Unlike English, which uses a single alphabet, Japanese uses three distinct scripts — often mixed together in a single sentence. This lesson introduces the big picture before you start learning individual characters.

The Three Scripts

Script Characters Purpose Example
Hiragana 46 base characters Native Japanese words, grammar たべる (taberu — to eat)
Katakana 46 base characters Foreign loanwords, emphasis, onomatopoeia コーヒー (koohii — coffee)
Kanji ~2,136 in common use Meaning-carrying characters from Chinese 山 (yama — mountain)

A typical Japanese sentence uses all three:

私はコーヒーを飲みます。 Watashi wa koohii wo nomimasu. "I drink coffee."

  • 私 and 飲 are kanji
  • は, を, みます are hiragana
  • コーヒー is katakana

Why Learn Hiragana and Katakana First?

Hiragana and katakana are the foundation of Japanese literacy:

  1. Every Japanese sound can be written in hiragana or katakana
  2. Furigana — small hiragana above kanji show pronunciation, so you can read anything
  3. Children's books are written entirely in hiragana
  4. Katakana lets you read thousands of English-origin loanwords immediately
  5. Textbooks use hiragana from lesson one — romaji (Roman letters) disappears quickly

Tip: Mastering hiragana and katakana typically takes 2–4 weeks of daily practice. This course gives you everything you need.

Hiragana: The Everyday Script

Hiragana (ひらがな) is used for:

  • Native Japanese words that are not written in kanji
  • Grammar particles — は (wa), が (ga), を (wo), に (ni), で (de)
  • Verb and adjective endings — 食べる (taberu), 高い (takai)
  • Furigana — pronunciation guides above kanji
  • Children's writing before they learn kanji

Hiragana characters are rounded and flowing:

あ い う え お    (a i u e o)
か き く け こ    (ka ki ku ke ko)
さ し す せ そ    (sa shi su se so)

Katakana: The Foreign-Word Script

Katakana (カタカナ) is used for:

  • Foreign loanwords — テレビ (terebi — television), パソコン (pasokon — personal computer)
  • Foreign names — マイク (Maiku — Mike), ロンドン (Rondon — London)
  • Onomatopoeia — ドキドキ (dokidoki — heart pounding)
  • Emphasis — similar to italics or bold in English
  • Scientific terms — ウイルス (uirusu — virus)

Katakana characters are angular and sharp:

ア イ ウ エ オ    (a i u e o)
カ キ ク ケ コ    (ka ki ku ke ko)
サ シ ス セ ソ    (sa shi su se so)

Romaji: Roman Letters

Romaji (ローマ字) is the representation of Japanese sounds using the Latin alphabet. There are several systems:

System し ち つ ふ
Hepburn (most common) shi chi tsu fu
Kunrei-shiki si ti tu hu
Nihon-shiki si ti tu hu

This course uses the Hepburn system, which is the most widely used and closest to English pronunciation.

Warning: Do not rely on romaji long-term. It is a stepping stone. Native Japanese text does not use romaji, and over-reliance on it slows your progress.

The Japanese Sound System

Vowels

Japanese has exactly five vowel sounds:

Vowel Pronunciation English Approximation
a ah "a" in "father"
i ee "ee" in "feet"
u oo "oo" in "food" (lips unrounded)
e eh "e" in "pet"
o oh "o" in "go"

These five vowels are consistent — they always sound the same, unlike English vowels.

Consonants + Vowels = Mora

Japanese sounds are built by pairing a consonant with a vowel:

k + a = ka (か)
s + u = su (す)
t + e = te (て)
n + i = ni (に)

Mora vs Syllable

Japanese rhythm is based on mora (拍, haku), not syllables:

Word English Syllables Japanese Mora
Tokyo (とうきょう) To-kyo (2) to-u-kyo-u (4)
Osaka (おおさか) O-sa-ka (3) o-o-sa-ka (4)
Nippon (にっぽん) Nip-pon (2) ni-p-po-n (4)

Each mora takes equal time to pronounce. This gives Japanese its characteristic even rhythm.

The Gojuuon Chart

All hiragana and katakana characters are traditionally arranged in the gojuuon (五十音, "fifty sounds") chart:

     a    i    u    e    o
—   あ   い   う   え   お
k   か   き   く   け   こ
s   さ   し   す   せ   そ
t   た   ち   つ   て   と
n   な   に   ぬ   ね   の
h   は   ひ   ふ   へ   ほ
m   ま   み   む   め   も
y   や        ゆ        よ
r   ら   り   る   れ   ろ
w   わ                  を
n   ん

The chart has 46 basic characters (some cells are empty). With dakuten (゛) and handakuten (゜) marks, plus combination characters, the total number of distinct sounds is around 100.

Summary

Japanese uses three scripts: hiragana for native words and grammar, katakana for foreign words, and kanji for meaning. This course focuses on hiragana and katakana — the essential 92 characters that form the foundation of Japanese literacy. Japanese sounds are built from five consistent vowels combined with consonants, producing a regular and learnable sound system. In the next lesson, you will learn your first 15 hiragana characters.
