Katakana the more angular form of kana (syllabic writing) used in Japanese. In contrast to the hiragana syllabary, which is used for those Japanese language words and grammatical inflections which kanji does not cover, the katakana syllabary usage is quite similar to italics in English.
Specifically, it is used for transcription of foreign language words into Japanese, the writing of loan words, for emphasis, to represent onomatopoeia, for technical and scientific terms, for names of plants, animals, minerals, and often Japanese companies.
Katakana are characterized by short, straight strokes and sharp corners, and are the simplest of the Japanese scripts.
The complete katakana script consists of 46 characters. There are 5 vowel sounds and 1 consonant sound. The other 40 characters are vowel-consonant unions much like in hiragana.
I will be going over each katakana individually like I am with hiragana. Here is a table so to better understand these concepts.
