Japanese Writing Systems: Complete Guide to Hiragana, Katakana, and Kanji

2025/06/15

If you’ve ever looked at Japanese text and felt overwhelmed by the mix of different characters, you’re not alone. Japanese uses three main writing systems simultaneously, and understanding how they work together is the key to reading Japanese successfully.

This comprehensive guide will break down each system and show you exactly when and how to use them.

Hiragana (ひらがな)

Hiragana is the foundation of Japanese writing and the first script you should learn. Whenever you just start out learning Japanese, hiragana is usually the first writing system you learn. Hiragana is technically a syllabary or a way of writing where symbols represent whole syllables (such as “ba” and “to”) instead of individual sounds.

What Hiragana Is and Its Basic Function

Hiragana is the backbone to all Japanese learning. It helps you learn the basics of pronunciation in Japanese and start to understand the building blocks of the language. Hiragana characters represent the 46 primary sounds used in Japanese. Each character represents a complete syllable sound rather than individual letters like in English.

The basic hiragana characters include:

• あ (a), い (i), う (u), え (e), お (o) – the five vowel sounds
• か (ka), き (ki), く (ku), け (ke), こ (ko) – and so on for each consonant-vowel combination

When and How Hiragana Is Used

Hiragana is used primarily for native or naturalized Japanese words and grammatical elements.

• Grammatical particles: は (wa), を (wo), に (ni), が (ga)
• Verb and adjective endings: 食べます (tabemasu – “to eat”), 大きい (ookii – “big”)
• Native Japanese words: especially when kanji would be too difficult or rare
• Children’s books and beginner materials: Furigana is hiragana and katakana characters written in small forms above kanji in order to show the pronunciation

Why Hiragana Is the Foundation

Hiragana pronunciation, unlike other writing systems, has incredibly consistent pronunciation. There are just three exceptions: The topic particle は normally pronounced ha, this character becomes wa when used as a topic particle; The object particle を normally pronounced wo but it becomes o when used as an object particle; The directional particle へ pronounced he except when used as a directional particle.

This consistency makes hiragana perfect for beginners to master Japanese pronunciation patterns before moving on to more complex scripts.

Learning Hiragana Effectively

Hiragana and Katakana are easy to learn, and can usually be mastered in 2 weeks.

• Use mnemonics
  Memory hints, aka mnemonics, are honestly the game changer in remembering foreign characters like hiragana, katakana, and even kanji. Using mnemonics, you can easily associate the shape of kana with the reading
  
• Focus on reading first
  Focus on reading first. Not writing. Learning to read is more important as the most common form of “writing” nowadays is typing
  
• Practice stroke order
  Proper stroke order helps with character recognition and writing fluency

Katakana (カタカナ)

Katakana represents the same sounds as hiragana but serves completely different purposes. Conveniently, the katakana character set covers the same sounds as hiragana. Some of the characters even look a bit similar, like ‘mo’ – も and モ – and ‘ya’ – や and ヤ.

What Katakana Is and Its Relationship to Hiragana

Japanese has two native writing styles — hiragana and katakana. Together they’re known as kana. In other words, hiragana and katakana are two different ways to write the same thing. Think of it like print and cursive in English – they represent the same sounds but look different and are used in different contexts.

When Katakana Is Used

Katakana is used primarily for foreign words and names, loanwords, onomatopoeia, scientific names, and sometimes for emphasis.

• Foreign loanwords: コーヒー (koohii – “coffee”), コンピューター (konpyuutaa – “computer”)
• Foreign names: アメリカ (Amerika – “America”), ジョン (Jon – “John”)
• Onomatopoeia: ワンワン (wanwan – dog barking sound)
• Scientific terms: Many scientific names use katakana
• Emphasis: Similar to using italics in English
• Company names: Many modern Japanese companies use katakana in their names

How Katakana Differs from Hiragana

While the sounds are identical, katakana characters are more angular and geometric compared to hiragana’s flowing, curved shapes. Hiragana is said to be cursive, while katakana is more angular.

Special Katakana Combinations

You can use small vowels to enrich katakana’s ability to reproduce loan words. The sounds di and ti can be written in katakana as ディ and ティ. These combinations help katakana represent foreign sounds that don’t naturally exist in Japanese.

• ティ (ti) – for words like “tea” or “team”
• ディ (di) – for words like “Disney”
• ファ (fa), フィ (fi), フェ (fe), フォ (fo) – for “f” sounds

Dakuten (濁点) and Handakuten (半濁点) for Hiragana and Katakana

The dakuten (濁点 – だくてん), colloquially ten-ten (点々 – てんてん, “dots”), is a diacritic most often used in the Japanese kana syllabaries to indicate that the consonant of a mora should be pronounced voiced. The handakuten (半濁点 – はんだくてん), colloquially maru (丸 – まる, “circle”), is a diacritic used with kana for morae pronounced with /h/ or /f/ to indicate that they should instead be pronounced with /p/.

What These Marks Are and How They Work

These small marks transform the pronunciation of basic kana characters.

• Dakuten (゛): Two small diagonal marks that look like quotation marks
• Handakuten (゜): A small circle

Sound Changes Created by Dakuten

The first diacritical sign is represented by two inverted commas or quotation marks called dakuten meaning point, dots or nigori that means “impurity, muddy or torbid”. Dakuten changes unvoiced consonants to voiced ones.

• K → G: か (ka) → が (ga), き (ki) → ぎ (gi)
• S → Z/J: さ (sa) → ざ (za), し (shi) → じ (ji)
• T → D/Z: た (ta) → だ (da), つ (tsu) → づ (zu)
• H → B: は (ha) → ば (ba), ひ (hi) → び (bi)

Sound Changes Created by Handakuten

These dakuten are only applied to the “ha, hi, hu, he, ho” column, and you won’t see them anywhere else. They’re small circles (instead of quotes) and they turn “ha, hi, hu, he, ho” into “pa, pi, pu, pe, po”.

• は (ha) → ぱ (pa)
• ひ (hi) → ぴ (pi)
• ふ (fu) → ぷ (pu)
• へ (he) → ぺ (pe)
• ほ (ho) → ぽ (po)

Examples in Both Scripts

The same rules apply to both hiragana and katakana.

• Hiragana: が (ga), じ (ji), だ (da), ば (ba), ぱ (pa)
• Katakana: ガ (ga), ジ (ji), ダ (da), バ (ba), パ (pa)

Small Hiragana and Katakana

The contracted sounds are combinations of the syllables ending in “i” with the three characters や (ya), ゆ (yu), よ (yo). The three syllables や, ゆ, よ are transcribed in the bottom right-hand corner and are smaller than the main character.

What Small Kana Are

Small versions of や (ya), ゆ (yu), and よ (yo) are combined with certain consonants to create new sounds that represent syllable combinations like “kya,” “sha,” “cha.”

How They Work

To make these sounds, you don’t need to learn more characters, but you do need to know about modifying and combining them. For combinations, we use smaller versions of the y-vowels ya (や), yu (ゆ), and yo (よ) to make new sounds, like sha (しゃ), chu (ちゅ), nyu (にゅ), and gyo (ぎょ).

Common Examples

Hiragana combinations

• きゃ (kya), きゅ (kyu), きょ (kyo)
• しゃ (sha), しゅ (shu), しょ (sho)
• ちゃ (cha), ちゅ (chu), ちょ (cho)
• にゃ (nya), にゅ (nyu), にょ (nyo)

Katakana combinations

• キャ (kya), キュ (kyu), キョ (kyo)
• シャ (sha), シュ (shu), ショ (sho)
• チャ (cha), チュ (chu), チョ (cho)

Pronunciation Tips

In the first case, the sounds defined as contracted are shorter and faster in pronunciation, whereas in the second they are distinct and marked. The small や, ゆ, よ must be pronounced quickly as part of a single syllable, not as separate syllables.

Kanji (漢字)

Kanji is the most complex part of the Japanese writing system. Kanji are Chinese characters and were Japan’s first writing system. They were first introduced to Japan over 1,500 years ago; hiragana and katakana actually evolved from these symbols! Kanji are complex characters that represent words or ideas.

What Kanji Are and Their Complexity

Each character has an intrinsic meaning (or range of meanings), and most have more than one pronunciation, the choice of which depends on context. Japanese primary and secondary school students are required to learn 2,136 jōyō kanji as of 2010. The total number of kanji is well over 50,000.

Unlike hiragana and katakana which represent sounds, kanji represent meanings and concepts.

• 水 (mizu/sui) = water
• 火 (hi/ka) = fire
• 人 (hito/jin/nin) = person
• 学校 (gakkou) = school

How Kanji Works with Hiragana

Kanji characters are used to write most content words of native Japanese or (historically) Chinese origin, which include many nouns, the stems of most verbs and adjectives, the stems of many adverbs, and most Japanese personal names and place names.

Japanese sentences typically combine kanji with hiragana.

• Kanji: Provides the main meaning (nouns, verb stems, adjective stems)
• Hiragana: Provides grammatical elements (particles, verb endings, adjective endings)

Example: 私は学校に行きます。

• 私 (watashi) = I (kanji)
• は (wa) = topic particle (hiragana)
• 学校 (gakkou) = school (kanji)
• に (ni) = directional particle (hiragana)
• 行き (iki) = go (kanji stem)
• ます (masu) = polite ending (hiragana)

Multiple Readings (On’yomi and Kun’yomi)

This change is also why many kanji have more than one pronunciation, their kun-yomi (Japanese readings of Kanji) and their on-yomi (Chinese-based readings of Kanji).

• Kun’yomi: Japanese reading, often used when kanji stands alone
• On’yomi: Chinese-based reading, often used in compound words

Example with 水 (water)

• Kun’yomi: みず (mizu) – used in 水 (mizu, “water”)
• On’yomi: すい (sui) – used in 水曜日 (suiyoubi, “Wednesday”)

Learning Strategy for Kanji

Kanji is usually the last system to be learned, even for native Japanese speakers!

1. Master hiragana and katakana first: Essential foundation
2. Start with common kanji: Learn the most frequently used characters
3. Use furigana: Furigana is hiragana that appears over unfamiliar kanji characters
4. Learn kanji in context: Focus on words and meanings, not isolated characters

The Long Vowel Sound

Long vowels are crucial for proper Japanese pronunciation and meaning. There are many words that look the same, where the only difference is that one has a long vowel and the other doesn’t.

Different Rules for Hiragana vs Katakana

The rules for writing long vowels differ significantly between the two scripts.

Hiragana Long Vowel Rules

You can extend the vowel sound of a character by adding either あ、い、or う depending on the vowel.

• Long あ (a): Add あ → かあ (kaa)
• Long い (i): Add い → きい (kii)
• Long う (u): Add う → くう (kuu)
• Long え (e): Usually add い → けい (kei)
• Long お (o): Usually add う → こう (kou)

Special patterns: Long e え sounds are followed by an extra い or え. Long vowels ending in o お are followed by an extra う. An exception to this is some words are written with a double お, such as in ooki 大き・おおき (big).

Examples:

• えいが (eiga) = movie
• おはよう (ohayou) = good morning
• おおきい (ookii) = big
• おねえさん (oneesan) = older sister

Katakana Long Vowel Rules

In Katakana, all long vowels are simply written with a long dash “―” (or an | if you are writing vertically), placed after the vowel being extended.

Examples:

• カー (kaa) = car
• コーヒー (koohii) = coffee
• スーパー (suupaa) = supermarket
• ボール (booru) = ball

Why Long Vowels Matter

It’s important to make sure you hold the vowel sound to the full length of both characters because there are many similar words that are only different by the length of the vowel.

Meaning differences:

• おじさん (ojisan) = uncle vs おじいさん (ojiisan) = grandfather
• かこ (kako) = past vs かこう (kakou) = let’s go

Writing Long Vowels

The chōonpu (長音符 – ちょうおんぷ) is usually used to indicate a long vowel sound in katakana writing, rarely in hiragana writing, and never in romanized Japanese.

• Hiragana: Follow the vowel combination rules
• Katakana: Always use the dash ー
• Mixed text: Use appropriate rules for each script

Putting It All Together

Almost all written Japanese sentences contain a mixture of kanji and kana. Because of this mixture of scripts, in addition to a large inventory of kanji characters, the Japanese writing system is considered to be one of the most complicated currently in use.

Why Japanese Uses Multiple Scripts

Japanese doesn’t use spaces, so reading something in just Hiragana or Katakana would be extremely difficult. Japanese has a lot of words that sound the same. Kanji helps differentiate these words by using different characters.

Learning Progression

For beginners, follow this recommended order.

1. Hiragana first: Master all 46 basic characters plus dakuten/handakuten
2. Katakana second: Learn the same sounds with different characters
3. Basic kanji: Start with the most common 100-200 characters
4. Advanced combinations: Small kana, long vowels, complex kanji

Practical Application

The scripts are often used in combination in texts: Kanji conveys the main content, while Hiragana expresses the grammatical structure, and Katakana highlights foreign words or names. This combination allows for a fluid and dynamic expression in written Japanese.

Understanding Japanese writing systems takes time and practice, but with the right approach and consistent study, you’ll be reading Japanese text confidently. Start with hiragana, build your foundation, and gradually add each system as you become more comfortable. Remember, even native Japanese speakers spend years mastering all aspects of their writing system!
