Hiragana and katakana: what each script does
A practical map of the two kana scripts and why Japanese uses both.
In short
Hiragana and katakana represent the same basic sound system, but they usually do different jobs in written Japanese.
How it works
Hiragana carries grammar endings and many native words. Katakana commonly marks loanwords, foreign names, sound effects, technical labels, or deliberate emphasis. A word does not become “more foreign” because of its pronunciation; script choice is a writing convention.
Useful contrast
Think of them as two alphabets with overlapping sounds but different visual roles. Kanji adds meaning-bearing characters alongside them.
Examples
これは ほんです。
This is a book.
コーヒーを のみます。
I drink coffee.
Common pitfall
Do not learn katakana as an optional extra. Everyday Japanese uses it constantly, especially for food, technology, brands, places and names.
