Japanese katakana (片仮名 or カタカナ), another Japanese alphabet, are more straight and have more angular corners in terms of shape as compared to hiragana.
1. Katakana are mainly used to express foreign words, foreign places, foreign countries, foreign names, things "loaned" from foreign languages.
For examples, エアコン (eakon) derived from the word air-con, ラジオ (rajio) derived from the word radio.
The foreign languages here refer not only to English, but also to languages like German, French, Dutch, etc. For example, アルバイト (arubaito which means"part-time job") comes from the German word "Arbeit".
2. Japanese katakana are also used to describe sounds, what we called onomatopoeia, or 擬音語 (giongo) in Japanese.
For example, ザーザー (za- za-) describes the sound of heavy rain. In a Japanese quiz show, when someone give an correct answer, the host will say ピンポーン (pinpo-n), indicates the answer is correct. If the answer is wrong, ブー (bu-) is used.
3. They are also used when someone wants to emphasize words in a sentence, the same effect as bold words.
See the katakana chart for the basic katakana characters, plus additional characters with 濁音 (dakuon), 半濁音 (handakuon), 拗音 (youon), and some descriptions on 促音 (sokuon) and 長音 (chouon).
Below are examples of some useful Japanese katakana...
