Doki Doki Spelling

  1. The phonetic symbols/letters “do” (ド) and “ki” (キ) make up the word, repeated two times in total. [3] Katakana is one of 3 writing systems primarily used in Japanese, along with hiragana (a set of phonetic symbols) and kanji (a large lexicon of Chinese characters). While a mix of hiragana and kanji is used for the majority of Japanese writing, katakana is often used to spell out loan words from other languages (e.g., a non-Japanese name like “Amanda”), as well as onomatopeic words like doki doki. [4]
    • Katakana and hiragana are both made up of the same phonetic symbols; however, the letters of each alphabet are written in slightly different ways. For example, the traditional Japanese greeting “konnichiwa” would be traditionally spelled as “こんにちは” using hiragana, but would appear as “コンニチワ” when spelled with katakana.
