Name on Residence Card, Passport, and Katakana Records

The name on your residence card follows your passport in Roman letters, but your bank, your ward office, and your My Number Card may each hold a slightly different katakana version of that same name.123 Those small differences are usually harmless until a contract, a payroll registration, or a ward-office check treats them as a mismatch.

Overview​

Japan records a foreign resident's name in two scripts across several unconnected systems. The passport and the residence card use Roman letters, while the ward office, banks, and employers use katakana.123 No central authority keeps those katakana renderings identical, so setting one standard spelling early saves repeated explanations later.

This article covers the documentation mechanics: which system records what, why variants arise, and how to hold one rendering across all of them. Family-law questions about surnames after marriage are covered alongside Koseki: Japan's Family Register Explained and Choosing Surnames in International Marriages.

How Each System Records Your Name​

The 在留カード (zairyū kādo, "residence card") is the national photo ID for mid- to long-term residents, issued by the 出入国在留管理庁 (Shutsunyūkoku Zairyū Kanrichō, "Immigration Services Agency").1 The 住民票 (jūminhyō, "residence record") is the municipal record of where you live, kept by your ward or city office.2 Each system has its own naming rule.

The passport and residence card standard​

The residence card shows your name in Roman letters exactly as it appears on your passport.1 The Immigration Services Agency transcribes from the passport at issuance, so the passport is the anchor document for the Roman-letter name.14

A legal-name change therefore reaches the card only after the home-country passport is renewed first. The card never updates ahead of the passport.4

Ward office, My Number, and bank katakana​

At first resident registration, the ward or city office records a katakana rendering of your name for jūminhyō purposes.2 Practices differ by municipality: some offices ask how you want it written, while others transcribe it for you, so confirm the spelling on the spot.2

The 個人番号カード (kojin bangō kādo, "My Number Card") carries the name as held on the jūminhyō record.5 Each bank then records katakana separately on its own account-opening form, and the spelling one bank accepts may differ from the next bank's.3

The diagram below shows how the Roman-letter anchor and the katakana branches relate.

Why Katakana Variants Arise​

Variants come from small transcription choices, not from error. Spacing between given and family names, separator dots, long-vowel marks, and middle-name handling each differ by institution and by the era when the registration was made.3

Middle names cause the most friction. Japanese-side forms often have short character fields, so a middle name gets shortened or dropped on one system while surviving in full on another.3 Counter staff compare character strings rather than people, so a dropped middle name reads as a mismatch rather than an abbreviation.3

Check the katakana spelling before you sign any new registration

Once a variant enters a system, every later correction costs a separate visit. Read the katakana back character by character at each new counter.3

Setting One Consistent Katakana Rendering​

Decide your standard katakana rendering at ward-office first registration and use it everywhere afterward.2 When a later bank or employer proposes a different spelling, present the jūminhyō as the standard and ask them to match it.23

Most banks and employers follow the ward-office record when shown it, since the ward-issued document is the most portable statement of the spelling.23 Keep a photo of the agreed rendering on your phone so every new registration starts from the same string.

One ward visit prevents a dozen bank corrections

Settling the spelling at the ward office takes minutes and propagates by example to every institution that copies it. Fixing five divergent bank spellings takes months.23

Good to know​

A missing middle name on one document is usually a mismatch, not a typo​

Staff at banks and ward counters treat a missing middle name as a different name, not as shorthand for the same person. Carry the document showing the full rendering so the connection is visible on paper.3

Banks follow the ward office record when you show it​

Banks set their own input rules, but in practice they accept the ward office's spelling when you present the jūminhyō at account opening or correction. New arrivals should therefore register at the ward office before opening bank accounts, in that order.23
