Why Hermione is written in katakana

In Japanese, foreign names are written in katakana — the angular script reserved for words borrowed from other languages. So on a form, a name tag, a delivery slip or a news article in Japan, Hermione appears as ハーマイオニー. This is the correct and respectful way a non-Japanese name is represented; it is not a kanji "translation". A Japanese reader sees ハーマイオニー and immediately reads it by its sound, Hāmaionī.

Katakana is a syllabary, so English sounds are fitted to the nearest Japanese syllables and every consonant (except ん) is followed by a vowel. That is why Hermione becomes ハーマイオニー rather than a letter-for-letter copy. More than one katakana spelling can be reasonable for the same name, which is why we flag whether a spelling is a long-established one or a natural default.
