How to Open a PO Box in Japan
There are two methods for opening a PO box in Japan:
Method 1: Japan Post, Japan’s official mail service, provides PO boxes for companies with a large volume of mail (enough for daily pick-ups).
Method 2: Private PO box companies offer PO services that include mail forwarding, and some also provide virtual access to physical mail, a bill payment service, and other mail-related features.
Today, we’ll explain how to open a PO box for both methods, breaking it down into easy-to-follow steps.
Method 1: Japan Post
Japan Post’s PO boxes are lockers with a key attached. Each locker is designated a specific number, and when you sign a contract, you are assigned a particular number/locker where you will receive your mail.
Requirements for opening a Japan Post PO box
While Japan Post’s PO boxes are free to use, there are conditions that you must fulfill to open a box with Japan Post.
You must be receiving mail almost every day
You must use the PO box for more than six months
You must be able to pick up mail without delay
Aside from these conditions, you’ll also need to find a post office with available PO box lockers in your area.
Steps for opening a Japan Post PO box
Follow these steps to open a Japan Post mailbox:
Step 1. Make sure you are eligible.
Read through Japan Post’s eligibility conditions and determine if you have sufficient mail volume to apply for a PO box. If you don’t have enough mail volume or don’t meet one of the other requirements, refer to Method 2 for opening a PO box in Japan.
Step 2. Search for availability.
Not all post offices in Japan offer PO boxes. And those that do may have limited availability. Japan Post has a search tool that lists all the post offices throughout Japan.
Input your local area, and then call the post offices and ask if they have PO boxes available. Note: You’ll most likely need to communicate with the post office in Japanese.
Step 3. Bring the required items.
Once you’ve found a post office with PO boxes available, gather the items you’ll need for the application process.
Personal identification: My Number card, driver’s license, passport, residence card, etc.
Step 4. Fill out the application form.
The application the post office will give you to fill out is the Application for Approval to Use a Japan Post Private Mailbox (郵便私書箱使用承認請求書 = yubin shishobako shiyou shonin seikyusho).
The information requested will be as follows:
Name
Impression of your inkan
Date you want to start receiving mail
How long you plan to use the PO box for
Your birthdate
Fill out the form and provide your ID.
Step 5. Wait for the post office to process your application.
The post office will process your application and make sure you are eligible to open a PO box with them. They will notify you once they have decided on your application.
Method 2. Private PO box services
Private PO box services in Japan have created an alternative for those who need what PO boxes can offer but aren’t eligible for a Japan Post mailbox. These services average between ¥1000 to ¥3000 per month, depending on the service's features.
How are Japan Post PO boxes different from private PO box services?
Here are the main points of difference between private PO box services and Japan Post’s PO boxes:
Japan Post’s eligibility requirements include enough mail volume for daily mail pickups
Private PO boxes have no such eligibility requirements
Japan Post’s PO boxes are located inside of your local post office
Private PO box services are not affiliated with Japan Post and are thus not located inside local post offices
Japan Post’s PO box service relies on the customer to come pick up their mail daily
While some private PO box services allow for direct pickup, most provide a mail forwarding service, and some offer a virtual mail dashboard for direct viewing of physical mail
Steps for opening a private PO box in Japan
Here are the steps for opening a private mailbox in Japan:
Step 1. Evaluate your options.
The first thing to consider is your comfort level with Japanese. If you can read Japanese with little issue, there are many Japanese PO box services to choose from. Some of the most well-known are PostCast and SRS .
However, if you would appreciate English customer support, English summary translations of your Japanese mail, and virtual mail access to the mail that arrives at your PO box, consider MailMate.
Step 2. Sign up with the mail service of your choice.
After evaluating your choices, sign up with the service that most makes sense for you. When signing up, you’ll be asked to verify your identity.
Each service provider will have a different method for this, but, likely, it won’t involve more than uploading some photo ID so they can verify that you are who you say you are. (For example, a picture of your My Number card with your ID number hidden).
Step 3. Redirect mail to your new PO box.
There are generally two methods for receiving mail at your new PO box.
Use Japan Post’s mail forwarding service to deliver your mail to your new PO box.
List your new PO box address as your point of contact so you start receiving mail there instead of your home address.
Step 4. Get notified each time you receive new mail.
Most private PO box services in Japan will offer some form of notification when you receive mail. The rare cases that don’t might instead bundle all the mail you receive and send it to you once a week or once a month instead of a notification.
You’ll likely be able to choose which you’d prefer when signing up and choosing your plan. With a service like MailMate, each mail’s outer envelope is scanned into your online dashboard, making it easy to take action on each piece of mail as it comes in.
