Katakana is one of the two modern Japanese kana syllabaries, alongside hiragana, used mainly for foreign loanwords, foreign names, scientific terms, onomatopoeia, and emphasis.

What it is

Katakana is a phonetic syllabary with 46 basic characters, each representing a mora (a sound unit). Its angular, straight-lined forms contrast with the curvier hiragana, but both scripts cover the same set of Japanese sounds.

Why it matters

Katakana is essential for writing loanwords and foreign names in Japanese, making it a key part of the writing system alongside hiragana and kanji. It also handles onomatopoeia and can add emphasis, similar to italics in English.

Key details

Katakana developed from simplified Chinese characters. It is used for scientific and technical vocabulary, and its characters are more linear than hiragana. The modern set has 46 basic symbols, with additional diacritics for modified sounds.
