Are you changing your address but unsure of how to navigate the post office? Or did you just realize that all of your important documents are still being sent to your old address? Don’t worry! This guide will help you understand how to set up mail forwarding in Japan and make your move a lot smoother.


Post Offices in Japan
It can be a little tricky at times to navigate the post office in Japan. Take it from someone who has changed addresses three times, writes letters to pen pals and friends in other countries every month, and sends packages quite often~ I’m basically a veteran when it comes to going to the post office.
So you can trust me when I say I’ve learned a thing or two about how to handle things like address changes in Japan and mail services.
To simplify it, mail forwarding means making sure that your mail gets redirected from your old address to your new address. This service is typically done through Japan Post and is valid for one year after you apply.
If you’re moving in Japan, this is one of the most important steps you don’t want to skip.
Why Does Forwarding Mail Matter?

There are honestly hundreds of reasons why forwarding your mail is important…especially in Japan. If you’ve lived here for even a short time, you probably already know that Japan still relies heavily on physical mail (and even fax machines ).
A lot of important things are still sent through the mail, including:
- Government documents
- Health insurance notifications
- Pension and tax notices
- Bank and credit card information
- Residence-related updates
Without properly setting up mail forwarding in Japan, you could easily miss:
- Important deadlines
- Bills or payment notices
- Official government communication
- Packages sent from your home country
And trust me… missing something like a tax notice is NOT something you want to deal with later.
This is why setting up Japan Post mail forwarding should be one of your top priorities when changing your address.
Steps to Setting It Up for the Post Office
This is a very simple guide on how to set up your Japan address forwarding service using three different methods.
1)Directly At the Post Office
This is the most straightforward method and one that I recommend.
You’ll need to:
-Bring your residence card
-Fill out a forwarding form (転居届 / tenkyo todoke)
-Provide your old and new addresses
The staff will guide you through everything, so don’t worry if your Japanese isn’t perfect.
2)Online
You can also apply online through the Japan Post website at this link here.
You’ll need to verify your identity, and you may receive a confirmation postcard. It can take a little longer than doing it in person because of that.
This option is convenient, especially if you prefer handling things digitally.
3)Mail-in Form
There’s also the option to send in a physical form by mail.
All you need to do it:
1.Pick up the form at a post office
2.Fill it out at home
3.Mail it in for processing
This is less common, but still a valid option if needed.
Processing Time?
It can take anywhere from 3 to 7 days for your mail forwarding service to activate.
Apply before you move or immediately after.
The sooner, the better, you don’t want to miss important mail or deal with overlapping addresses.
My Opinion
Personally, I recommend going into the post office and filling it out in person~
The staff are usually very polite and extremely helpful. I do this every time I move, and it’s always been a quick and easy process. If there’s anything you don’t understand, they can explain it right away, which is much easier than trying to figure everything out online by yourself.
If you’re new to Japan or unsure about the process, this is definitely the safest option.
What Can Be Forwarded at the Post?

Most of the time, items that can be forwarded through Japan Post’s forwarding service:
- Letters
- Packages
- Registered mail
However, there are some limitations.
Some delivery courier services (like private companies) may NOT forward your mail. Additionally, certain government documents may not be automatically forwarded depending on the type.
This is why it’s extremely important to:
- Update your address with all institutions
- Double-check your documents
- Make sure everything is properly registered
Basically… don’t rely ONLY on forwarding.
Common Mistakes
You’re human and mistakes happen. You definitely wouldn’t be the only one to mess something up during a move.
Some mistakes that happen are:
- Forgetting to update your address with banks, credit card companies, and other services
- Not realizing that the forwarding service is only valid for one year
- Writing your name incorrectly (I made this mistake and do everything to make sure I don’t make the same mistake again)
- Mixing up romaji, katakana, or English spelling
- Forgetting middle names
- Not matching your residence card exactly
Happy Forwarding!

If you’re moving and wondering how to stay organized, I highly recommend setting reminders and creating a checklist. Try to handle your Japan mail forwarding setup at the same time as you register your new address at city hall or update your bank information
AGAIN, please make sure your name matches exactly how it appears on your residence card.
You’ve got this in the bag! 🙂
