Tips for writing Day in katakana
- Katakana is written left to right like English, or top to bottom in vertical text. Keep every character the same size except the small ones.
Day on Japanese forms
Example full name: John Day → ジョン・デイ (Western order, names separated by ・).
Most Japanese forms put the family name first: デイ ジョン. In a フリガナ (furigana) field write it in katakana; if the field says ふりがな use hiragana (でい じょん); some bank and card forms ask for half-width katakana (ﾃﾞｲ ｼﾞｮﾝ).
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.
