Katakana are also used for onomatopoeic words like “ding”, or for making words look important, or for scientific names such as the names of birds. Sometimes sentences in books or cartoons may be written in katakana to show that someone is supposed to be speaking with a foreign accent. It is often used to write the names of Japanese companies, i.e. Suzuki is written スズキ, and Toyota is written トヨタ.
