What to Do When Your Name Changes While Living in Japan

If you are a foreign national living in Japan long-term, there are situations where your name may change — due to marriage, a legal name change, or an update to your home country’s official documents.

When this happens, many people find themselves wondering:

“Is updating my passport enough?”

“Do I need to change my Residence Card too?”

“How long do I have to report the change to immigration?”

In Japan, if the name on your Residence Card has changed, you are required to file the relevant notification.

This article walks you through the steps you need to take when your name changes while living in Japan.

A Name Change Requires a Notification

Foreign nationals on a medium- to long-term stay in Japan may have a legal obligation to report any changes to the information recorded on their Residence Card.

The most common changes that fall under this obligation include:

  • Change of given name
  • Change of family name
  • Change of nationality
  • Correction of date of birth
  • Change of gender

Start with Updating Your Passport

In most cases, a name change begins with your home country’s government.

For Korean nationals, the most common scenarios that lead to a new passport with an updated name are:

  • A legal name change
  • A name change due to marriage

In Japan, it is important that your passport and Residence Card information match, so the first step is to make sure your passport reflects your new name. If you renew your passport while living in Japan, What to Do After Renewing Your Passport While Living in Japan covers the steps you need to take.

You Need to File a Notification of Change of Registered Items

Once your name has changed, you must go through the notification of change of registered items process at the Immigration Services Agency of Japan.

Your Residence Card is the official document that proves your status of residence in Japan. Leaving it with an outdated name is not advisable.

In everyday life in Japan, your Residence Card information is used in a wide range of situations, and a name mismatch can cause problems at places such as:

  • Banks
  • Your employer
  • Mobile phone carriers
  • Government offices

What Is the Deadline?

As a general rule, when a change occurs in your name, nationality, date of birth, or gender, you must file a notification within 14 days of the change.

If your passport name has been updated, it is best to begin the process as soon as possible.

Where Do You File?

Changes to the registered items on your Residence Card are handled at the Immigration Services Agency.

Official information regarding immigration procedures in Japan can be found on the Immigration Services Agency’s official website.

What Documents Are Typically Required?

Requirements may vary depending on your situation, but the following documents are commonly used:

  • Residence Card
  • Passport
  • Documentation proving the name change
  • Application form

For example, documents that may be required to prove a name change include:

  • Certificate of name change
  • Family relationship certificate
  • Marriage-related documents

Will a New Residence Card Be Issued?

If the name change is approved, a new Residence Card reflecting the updated name will be issued.

This means your card will be replaced with an updated official version — not simply annotated with a note.

Check City Hall Registrations Too

After a name change, it is a good idea to check not only the Immigration Services Agency but also other government offices.

Common registrations to review include:

  • Resident registration (住民登録)
  • National Health Insurance
  • National Pension
  • My Number (Individual Number) records

Additional update procedures may be required depending on your circumstances.

Banks Need to Be Updated Too

This is something many people overlook.

If you have a Japanese bank account, you will need to notify the bank of your name change.

For example, the following information may still be registered under your old name:

  • Account holder name
  • Cash card details
  • Online banking information

A name mismatch can cause issues during transfers or identity verification.

Notify Your Employer

If you are employed at a company in Japan, you should also inform your HR department of your name change.

The following items are among those that may be affected:

  • Payroll records
  • Social insurance
  • Tax-related documents

Update Your Mobile Phone and Credit Cards

In Japan, identity verification standards tend to be strict.

The following services may also require a name change update:

  • Mobile phone contract
  • Credit cards
  • Securities accounts
  • Other financial services

The Same Applies When Your Name Changes Due to Marriage

The same steps apply if your name or family name changes due to:

  • An international marriage
  • A marriage registration filed in Korea

If your passport and Residence Card show different names, it can create complications down the line during visa renewals or other administrative procedures.

What Happens If You Don’t Update Your Name?

A major problem won’t necessarily arise immediately.

However, the following types of mismatches may occur:

  • Your passport name and Residence Card name do not match
  • Your bank records show a different name
  • Your employer’s documents contain an inconsistency

In particular, consistency of information is important when renewing your visa or applying for permanent residence, so it is best to sort things out in advance.

Do Permanent Residents Also Need to File a Notification?

Yes.

Permanent residents are also foreign nationals who hold a Residence Card, so if their name changes, they are subject to the same notification requirement.

Wrapping Up

When your name changes while living in Japan, simply getting a new passport is not sufficient.

It is also a good idea to update your registered information at the following places:

  • Banks
  • Your employer

  • Insurance providers
