Tips for writing Kai in katakana

Kai on Japanese forms

Example full name: Kai Smith → カイ・スミス (Western order, names separated by ・).

Most Japanese forms put the family name first: スミス カイ. In a フリガナ (furigana) field write it in katakana; if the field says ふりがな use hiragana (すみす かい); some bank and card forms ask for half-width katakana (スミス カイ).

Japan has no official katakana spelling for foreign names. Once you use a spelling for a bank account, phone contract or employer, keep using the same one so your records match.

FAQ

How do you write Kai in Japanese?

Kai is usually written カイ (kai) in katakana, the script Japanese uses for foreign names. In hiragana it is かい.

Is there a kanji for Kai?

No. Foreign names have no official kanji; they are written in katakana. Kanji versions offered online (ateji) are chosen only for sound and look, and their "meanings" are made up, so this site does not provide them.

How spellings are chosen: the first spelling is the one most commonly used for this name in Japanese books, media and everyday writing, checked against the Japanese government's rules for writing foreign words (Cabinet Notice No. 2 of 1991, 外来語の表記). The list was compiled by this site; it is not an official register. Pronunciation matters more than spelling — if your name is pronounced differently, the katakana can differ too.
