Three Writing Systems

Open any Japanese book, website, or sign, and you will see something that looks chaotic at first glance: a mix of curvy characters, angular characters, and complex kanji, often all in the same sentence.

This is not random. Japanese uses three writing systems that each serve a distinct purpose. Once you know when and why each script appears, reading Japanese gets much easier.

The three scripts at a glance

Script	Name	Character type	Primary use
ひらがな	Hiragana	Curvy, flowing	Native Japanese words, grammar, particles, furigana
カタカナ	Katakana	Angular, sharp	Foreign loanwords, onomatopoeia, emphasis
漢字	Kanji	Complex logographs	Content words: nouns, verb stems, adjective stems

All three show up together in most sentences. Here is a real example:

私は毎日(まいにち)コンビニで弁当(べんとう)を買(か)います。

Part	Script	Role
私は	Hiragana + Kanji	“I” (subject marker)
毎日	Kanji	“every day” (content word)
コンビニ	Katakana	“convenience store” (loanword)
で	Hiragana	Location particle “at”
弁当	Kanji	“bento / boxed lunch”
を	Hiragana	Object marker
買	Kanji	“buy” (verb stem)
います	Hiragana	Polite verb ending

Translation: “I buy a bento at the convenience store every day.”

Three scripts in one sentence. Each piece has a clear job.

In 私は毎日コンビニで弁当を買います, which script is コンビニ written in, and why?

A. Katakana — it is a foreign loanword (convenience store)B. Hiragana — it is a grammar particleC. Kanji — it is a native content wordD. Romaji — it is romanized English

You already know the kanji parts: 毎日 (every day, like 每日), 弁当 (bento, related to 便当), 買 (buy, like 买). The hiragana is doing what pinyin does in Mandarin: showing you how to pronounce and how grammar connects. The katakana marks a foreign-origin word, just as Mandarin might write 咖啡 instead of inventing new characters for “coffee.”

Hiragana: the native glue

平仮名(ひらがな) (hiragana) is Japan’s primary phonetic alphabet. All 46 basic characters represent syllables, not individual consonants or vowels, but complete syllable units like か (ka), し (shi), ん (n).

When hiragana is used

• Grammar particles: は, が, を, に, で, へ, と, も
• Verb and adjective endings: 食べます, 美しい, 行った
• Native Japanese words without kanji: これ, あれ, さようなら
• Furigana (reading aids above kanji): 漢字(かんじ)
• Children’s books before kanji is learned

Think of hiragana as Japanese’s pinyin and grammar rolled into one. In Mandarin, 我在学校学习 mixes characters (content) with implicit grammar. In Japanese, the grammar is visible, and it is almost always written in hiragana. Learn the 46 characters and you can read the connective tissue of most sentences.

Where hiragana came from

Hiragana evolved from cursive handwriting (草書(そうしょ)) of kanji. Scribes simplified full kanji characters into quick, flowing strokes for everyday writing.

Hiragana	Evolved from kanji	Mandarin you know	Original meaning
あ	安(あ)	安 (ān)	peace, cheap, safe
い	以(い)	以 (yǐ)	by means of
う	宇(う)	宇 (yǔ)	eaves, universe
か	加(か)	加 (jiā)	add
き	幾(き)	几 (jī)	how many
さ	左(さ)	左 (zuǒ)	left
た	太(た)	太 (tài)	great, thick
な	奈(な)	奈 (nài)	Nara (place name)
の	乃(の)	乃 (nǎi)	therefore
ま	末(ま)	末 (mò)	end

Look at あ. It is clearly a cursive simplification of 安. Once you see the connection, hiragana stops feeling like random squiggles and starts feeling like abbreviated kanji you already know.

The kanji origins of hiragana are characters you recognize: 安, 加, 左, 太. Japanese women of the Heian court (9th–12th century) pioneered hiragana for writing poetry and literature. It was called 女手(おんなで) (women’s hand). The “men’s hand” (男手(おとこで)) was kanji itself. Knowing the kanji roots gives you a memory anchor for each hiragana character.

Katakana: the foreign word marker

片仮名(カタカナ) (katakana) is the second phonetic alphabet. Same 46 sounds as hiragana, but written with straight, angular strokes. It covers the exact same syllables; only the shapes differ.

When katakana is used

• Foreign loanwords: コーヒー (coffee), パソコン (personal computer), アルバイト (part-time job, from German Arbeit)
• Onomatopoeia: ワンワン (woof woof), ガタガタ (rattling sound)
• Scientific names: ミネラル (mineral)
• Emphasis (like italic/bold in English): 本当にダメだ！
• Transcription of foreign names: トランプ, ベッキー

If you speak English, you already know many katakana words. You just need the alphabet. ホテル is hotel. レストラン is restaurant. タクシー is taxi. Learn katakana early and you recognize a large vocabulary instantly.

Where katakana came from

Katakana evolved differently from hiragana. Not from cursive writing, but from extracting single components (often the radical or a distinctive part) of kanji:

Katakana	Extracted from kanji	Mandarin you know	Original meaning
ア	阿(あ)	阿 (ā)	prefix, slope
イ	伊(い)	伊 (yī)	that one (classical)
ウ	宇(う)	宇 (yǔ)	eaves, universe
カ	加(か)	加 (jiā)	add
キ	幾(き)	几 (jī)	how many
サ	左(さ)	左 (zuǒ)	left
タ	太(た)	太 (tài)	great, thick
ナ	奈(な)	奈 (nài)	Nara
ノ	乃(の)	乃 (nǎi)	therefore
マ	末(ま)	末 (mò)	end

Notice that many katakana and hiragana share the same origin kanji. 加 gives us both か and カ. 左 gives us both さ and サ. They are two different simplification styles of the same source material.

This is directly analogous to simplified vs traditional Chinese. China and Japan took the same classical characters and simplified them differently for everyday writing. 加 became か in cursive (hiragana) and カ as a component extraction (katakana), just as 學 became 学 in simplified Chinese but 學 in traditional. Same source, different simplification paths.

Kanji: the characters you already know

漢字(かんじ) (kanji) are the logographic characters borrowed from Chinese. They carry meaning (and sometimes sound) and form the backbone of Japanese vocabulary.

When kanji is used

• Content words: nouns (学校), verb stems (食べる → 食), adjective stems (美しい → 美)
• Names: 田中 (Tanaka), 山田 (Yamada), 東京 (Tokyo)
• Anything where meaning density matters. Kanji packs more meaning per character than kana.

In a typical Japanese sentence, kanji carries the meaning. Hiragana carries the grammar and pronunciation glue.

All three together

Let us dissect another sentence piece by piece:

彼(かれ)は新(あたら)しいパソコンを買(か)った。

“He bought a new computer.”

Segment	Script(s)	Analysis
彼	Kanji	“he” (content word)
は	Hiragana	Topic particle
新	Kanji	“new” (adjective stem)
しい	Hiragana	Adjective ending
パソコン	Katakana	“personal computer” (loanword)
を	Hiragana	Object particle
買	Kanji	“buy” (verb stem)
った	Hiragana	Past tense ending

Kanji carries meaning. Hiragana handles grammar. Katakana marks foreign imports.

Which writing system would you expect for the word パソコン (personal computer)?

A. Katakana — foreign loanwordB. Hiragana — native grammarC. Kanji — content word with meaningD. All three mixed together

False Friend 偽りの友

彼(かれ) (he/him) uses the kanji 彼, which in Mandarin means “that” (彼 bǐ). Same character, different primary meaning in Japanese. Context usually makes it clear, but do not assume shared kanji always work the same way in both languages.

Romaji: romanization

Romaji (ローマ字) is the romanization of Japanese using the Latin alphabet: konnichiwa, arigatou, sushi.

It is useful for:

• Absolute beginners getting started
• Typing on computers and phones (you type romaji, it converts to kana/kanji)
• Showing pronunciation to non-Japanese readers

But you should move past romaji quickly. Reading Japanese in romaji is like reading Mandarin in Wade-Giles: it works, but it cuts you off from the actual writing system and slows you down over time.

Romaji is fine as a starting crutch. Use it for your first week if you need to. Once you know hiragana (which takes less time than you might expect), switch your input method to kana input and stop relying on romaji transcriptions. Actual Japanese text on signs and menus becomes readable much sooner that way.

How the systems interact: furigana

Japanese has a built-in reading aid system: 振(ふ)り仮名(がな) (furigana), small hiragana printed above or beside kanji to show pronunciation.

Example: 漢字(かんじ)

Children’s books, learner materials, and difficult kanji in newspapers all use furigana. As a Mandarin speaker, furigana lets you read the kanji for meaning (from Chinese) and the furigana for pronunciation (in Japanese) at the same time.

Deep Dive 深掘り

Why Japan adopted Chinese characters

Japan’s adoption of kanji was not a single event. It was a centuries-long process shaped by religion, politics, and prestige.

5th–6th century: Chinese writing arrives with Buddhist scriptures and Confucian texts via the Korean peninsula. The Japanese court sends missions to Tang China to study writing, law, and culture. Kanji becomes the mark of literacy and civilization.

7th–8th century: The 万葉仮名(まんようがな) (Manyōgana) period. Japanese is written entirely in kanji, used for both meaning and sound. This is awkward (imagine writing English using only Chinese characters phonetically), but it works.

9th century: Hiragana and katakana emerge as shorthand systems. The 平(へい)安時代(じだい) (Heian period) sees a literary golden age. The Tale of Genji (源氏物語) is written primarily in hiragana mixed with kanji.

Post-WWII reforms: Japan simplifies many kanji forms (similar to China’s simplified character reform), limits the official character list to ~2,136 常用漢字(じょうようかんじ), and standardizes readings.

The key insight for Mandarin speakers: Japan went through its own “character reform,” so some kanji match your simplified Chinese, some match traditional, and some are Japan-specific simplifications (e.g., 学 vs 學, 国 vs 國, 発 vs 發). Knowing both simplified and traditional Chinese gives you even more overlap.

Japan did not replace kanji with a single phonetic script. Instead, hiragana and katakana grew alongside it over centuries: kanji from Chinese literary tradition, hiragana from court poetry and native prose, katakana from shorthand and later from loanwords. The three scripts reflect different historical layers, not a design anyone planned from scratch.

What to learn first

Most Mandarin-speaking learners start with hiragana, since it covers grammar, particles, and pronunciation. Katakana comes next and gives you access to thousands of English loanwords. After that, build a kanji strategy that bridges from Mandarin rather than memorizing from scratch. Drop romaji as soon as hiragana feels comfortable.

That order works well for many people, but it is not a rule. Some learners pick up katakana first because the loanwords feel familiar. Others start reading kanji they already know from Chinese and fill in hiragana later. Jump around if that keeps you motivated.

The next chapter covers one of the most important concepts for leveraging your Mandarin: on’yomi and kun’yomi, the two reading systems for kanji, and why one of them sounds remarkably like the Chinese you already speak.

Key takeaways

• Japanese uses three scripts together: hiragana (grammar/native), katakana (foreign/emphasis), kanji (content words)
• Hiragana evolved from cursive kanji; katakana from extracted kanji components — both share kanji roots you know
• Kanji carries meaning density; hiragana is the connective glue; katakana signals imported vocabulary
• Romaji is a starting crutch — move to hiragana input as soon as you can read the 46 characters
