How to write Koa in katakana
Japanese writes foreign names in katakana, one of its two alphabets, by sound rather than by spelling. Koa becomes コア, made of these parts:
| Katakana | Sound | Note |
|---|---|---|
| コ | ko | |
| ア | a |
When you write a full name, Japanese puts a middle dot between the first and last name, for example コア・スミス for Koa Smith.
