1. Read the label beside the name field
Japanese forms often split one name into several fields. The label tells you which representation belongs there.
- 姓 / 名: family name / given name
- セイ / メイ: family-name reading / given-name reading, usually Katakana
- フリガナ: phonetic reading, commonly Katakana
- ローマ字氏名: name in Latin letters
2. Check full-width versus half-width
A form can reject ordinary Latin characters when it requires 全角, or reject full-width characters when it requires 半角. Spaces have widths too. Use the requested result rather than retyping the name by eye.
3. Match the spelling already on file
Katakana spellings are not always unique. Banks, carriers, employers, and government systems may compare against the spelling stored on an existing account. When possible, copy that exact spelling.
Common name-field mistakes
- Entering Latin letters in a Katakana field
- Keeping a middle dot or space that the field does not allow
- Putting the full name into separate surname or given-name fields
- Changing the Katakana spelling from an existing account
- Using browser autofill that inserts normal spaces or punctuation
Frequently asked questions
Why does my name look correct but still fail?
The form may be checking character type, width, spacing, or an exact registered spelling rather than whether the name looks readable.
What should I enter in a フリガナ field?
For a foreign name, enter the phonetic reading in full-width Katakana unless the form explicitly asks for Hiragana.
Should I include my middle name?
Follow the form’s instructions and match the identity record used by that service. If the service already has your name, keep the same spelling and order.
