Hiragana vs Katakana: What's the Difference?

Japanese uses three distinct writing scripts — hiragana, katakana, and kanji — and fluent reading requires all three. Hiragana and katakana are the two kana syllabaries, and beginners often hear both names together without understanding how they differ. This post focuses entirely on that question: what each script is, what it looks like, what job it does, and which to tackle first.

TL;DR: Hiragana and katakana each have 46 base characters and represent the exact same set of sounds. The difference is not phonetic — it is functional. Hiragana handles native Japanese words and grammar; katakana handles foreign loanwords, foreign names, onomatopoeia, and emphasis. Learn hiragana first.

What is hiragana?

Hiragana (ひらがな) is a phonetic syllabary — each character represents one sound unit (mora), not a meaning. It developed during the Heian period (roughly the 9th century) from the cursive calligraphic form of Chinese characters, a style called sōsho (草書). Scribes simplified full kanji into flowing, rounded shapes, and hiragana grew from that process. Because it originated in cursive brushwork, its characters have a distinctly soft, rounded quality.

Hiragana is foundational to reading Japanese. Grammatical particles like は, を, が, and に are written in hiragana. So are verb endings, adjective endings (okurigana), and many native Japanese words that either lack kanji or whose kanji are so rarely used that writers prefer the kana form. Hiragana also appears as furigana — small reading guides printed above kanji in children's books, learner texts, and difficult passages in newspapers.

What is katakana?

Katakana (カタカナ) is the second phonetic syllabary. It emerged during the same Heian period but from a different source: Buddhist monks and scholars took fragments or partial strokes from Chinese characters — rather than simplifying whole characters — to use as shorthand annotations in classical texts. Those extracted strokes produced the angular, sharp forms that distinguish katakana visually from hiragana.

Katakana's dominant job in modern Japanese is writing gairaigo — foreign loanwords, primarily from English, French, German, and Portuguese. Words like コーヒー (kōhī, "coffee"), テレビ (terebi, "television"), and スマホ (sumaho, "smartphone") are all written in katakana. Beyond loanwords, katakana appears in onomatopoeia, foreign names, scientific names for animals and plants, and as a stylistic emphasis marker.

How many characters does each script have?

Both hiragana and katakana have exactly 46 base characters. These 46 cover every mora (sound unit) in standard Japanese — the five vowels, and consonant-vowel combinations across roughly ten consonant rows, plus the standalone nasal ん/ン.

The full usable set expands beyond 46 when you add:

• Dakuten (゛) — a pair of small tick marks that voice a consonant (か ka → が ga, for example)
• Handakuten (゜) — a small circle applied to the は row only, producing the ぱ/パ row (pa, pi, pu, pe, po)
• Combination characters (yōon) — a full-size character followed by a small ya/yu/yo (like きゃ/キャ for "kya")

With all of these, the practical usable inventory covers approximately 71 distinct sounds in each script. The exact total depends on how you count the combination characters, but 46 base is the number to remember.

Exam tip: A common beginner question is whether hiragana and katakana have different character counts or represent different sounds. They don't. Both scripts have 46 base characters and cover the same phonetic inventory. The difference is entirely about context and function, not sound.

What is hiragana used for?

Hiragana carries the structural weight of the Japanese language. You will find it in:

• Native Japanese words (wago) that are written without kanji, either because no kanji exists for them or because the kanji has fallen out of everyday use
• Grammatical particles: は (wa), を (o), が (ga), に (ni), で (de), and others that mark the role of each word in a sentence
• Verb and adjective endings (okurigana): the kanji 食 (eat) is followed by hiragana べる to complete the verb 食べる (taberu)
• Furigana: small hiragana printed above or beside kanji to indicate pronunciation, common in children's materials and learner texts
• Children's books and early-grade writing: hiragana is the first script Japanese children learn and is used before kanji instruction begins

This breadth means hiragana appears in virtually every sentence of Japanese. It is the glue of the writing system.

What is katakana used for?

Katakana marks words and contexts that are treated as external to the native Japanese lexicon. The main uses are:

• Foreign loanwords (gairaigo): any word borrowed from a non-Chinese foreign language is written in katakana — アメリカ (Amerika, "America"), パン (pan, "bread" from Portuguese), アイスクリーム (aisukurīmu, "ice cream")
• Foreign personal and place names: マリア (Maria), ロンドン (Rondon, "London"), フランス (Furansu, "France")
• Onomatopoeia: sound and texture words in manga and everyday speech frequently appear in katakana — ドキドキ (dokidoki, heart pounding), ガーン (gān, a stunned reaction), ザーザー (zāzā, heavy rain)
• Scientific and biological names: plant and animal species names in scientific or botanical writing often use katakana, so サクラ (sakura, cherry blossom) appears in botanical contexts where the kanji 桜 might otherwise be used
• Emphasis: katakana in a sentence otherwise written in hiragana and kanji functions like italics in English — it singles out a word for stress or stylistic effect
• Company names and product branding: many Japanese companies and products write their names in katakana, such as ソニー (Sonī, "Sony") or トヨタ (Toyota)

How do hiragana and katakana look different?

The visual difference is immediate once you know what to look for. Hiragana is curvy and rounded — its strokes flow together in loops and sweeping curves that reflect its origin in fast cursive brushwork. Katakana is angular and sharp — its strokes are short, straight lines and clean intersections that reflect its origin in clipped fragments of formal kanji.

Compare the character for the sound "ki": hiragana き has a rounded, four-stroke form with overlapping curves. Katakana キ is three straight lines at angles. Both sound identical — /ki/ — but they look nothing alike.

This visual contrast is the fastest way for a beginner to identify which script they are looking at in real text. Rounded forms are hiragana; angular forms are katakana. Kanji, the third script, is visually more complex than either.

Which should you learn first?

Learn hiragana first. Hiragana appears in every sentence, covers all grammatical particles and verb endings, and is the script used in furigana — the reading guides that help you decode kanji. Almost all beginner learning materials and textbooks assume hiragana literacy from the very first page.

For a step-by-step method to memorize all 46 base hiragana characters, see the companion post How to Learn Hiragana: The Complete Beginner's Guide.

Once hiragana is solid, katakana follows naturally. The sound system is identical — you already know all the sounds — so you are learning only new shapes for familiar phonemes. Most learners finish katakana noticeably faster than hiragana for exactly this reason.

Do you need to learn both?

Yes — and there is no practical alternative if you intend to read real Japanese. A menu at a Japanese restaurant will use katakana for loanword dishes alongside hiragana particles and kanji. A manga page will mix all three scripts within a single speech bubble. A subway sign might write a station name in kanji with furigana in hiragana alongside a foreign tourist destination in katakana.

Knowing only hiragana leaves entire categories of vocabulary — everything borrowed from foreign languages, onomatopoeia, many brand names — unreadable. Both scripts are essential; hiragana is simply the more urgent starting point.

If you are working toward the JLPT N5 proficiency level, reading ability in both scripts is a prerequisite. See What Is JLPT N5? for what the exam requires and how to structure your study plan around it.

Frequently asked questions

Is hiragana or katakana harder to learn?

Most learners find hiragana marginally harder to learn from scratch because the rounded strokes are more varied and the characters are more visually distinct from each other. Katakana, with its angular forms, can look similar across characters (ソ and ン, or シ and ツ, are classic confusion pairs). In practice, the difficulty difference is small — what matters more is the order: learn hiragana to solid recognition before starting katakana.

Can the same word be written in either hiragana or katakana?

Phonetically, yes — any Japanese word can be rendered in either script because both cover the same sounds. But in standard written Japanese, which script is used is determined by convention and function, not free choice. A loanword like "coffee" is written コーヒー in katakana; writing it in hiragana would be nonstandard and would signal unusual emphasis or stylistic effect. Native Japanese words use hiragana (or kanji with hiragana endings). The conventions are stable enough that deviating from them is immediately noticeable to a Japanese reader.

Do Japanese children learn both scripts at once?

No. Japanese children learn hiragana first, typically in the first months of elementary school, reaching full hiragana literacy before katakana instruction begins. Katakana is introduced next, and kanji study starts gradually from first grade and continues through middle school and beyond. The sequence reflects what educators and the writing system's structure naturally suggest: hiragana is foundational, katakana builds on top of it.
