Jack in Japanese Katakana

Tips for writing Jack in katakana

• Write the small ャ at about half size, in the lower left of the square (in horizontal writing). ジャ is one sound, ja.
• The small ッ is a short pause that doubles the next consonant. Write it half size; a full-size ツ would be read "tsu".
• Japanese syllables end in a vowel (except ン), so the final consonant of Jack becomes ク (ku). Say it lightly.
• 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.

Jack on Japanese forms

Example full name: Jack Smith → ジャック・スミス (Western order, names separated by ・).

Most Japanese forms put the family name first: スミス ジャック. 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 じゃっく); some bank and card forms ask for half-width katakana (ｽﾐｽ ｼﾞｬｯｸ).

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.
