The Katakana block includes characters used in the Katakana script, which, along with Hiragana, forms one of the two syllabaries used in the Japanese writing system. Katakana is used primarily for foreign loanwords, the names of plants, animals, and companies, and for emphasis, much like italics in English. This block includes all 46 basic Katakana characters, as well as several extended Katakana characters and marks. Katakana plays a crucial role in modern Japanese, especially in the context of technology, international communication, and popular culture..
