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