What Is Katakana?

Katakana (カタカナ) is one of the three scripts in Japanese, alongside hiragana and kanji. While hiragana is typically used for native words and grammar, katakana shares the same set of sounds but is reserved for foreign or stylistic elements.

If you’ve already mastered hiragana, katakana will feel familiar in sound but looks distinct with straight lines and angles. You’ll see it often on packaging, menus, signs, and brand names.
