How to Call Japan from the US?

How to dial Japan from the US? Making an international call to a Japanese landline number takes a bit different process than calling a cell phone number. So, we have two situations on our hands. Let’s explain each of these scenarios separately:

How to Call a Japanese Mobile Number from the United States?

Just follow the four simple steps mentioned below to call a Japanese number from the US.

step#1: Dial the US Exit code

The exit code for the US is 011. So, if you’re calling a number outside of the US, this code tells the carriers you’re trying to make an international code. Or, you can just type the (+) symbol if you’re calling from a mobile or VoIP system.

This is a standard procedure you need to follow for every international call from inside the US.

Step#2: Country code

The International Telecommunication Union is an international body that assigns unique codes to countries worldwide.

These codes help to guide international incoming calls. Japan country code is 081. You need to add this after the 011 or (+) symbol for making international calls to Japan from the US.

Step#3: Add Area Code

Just like every country, Japan has been split into many regions and separate area codes have been designated for them. Japan area codes may be 1 to 5 digits long. Add your area code after the country code.

Check out for a complete list of area codes for calling Japan or for any country you’re looking for.

Step#4: Add the mobile number

Finally, you’ll have to add the mobile number after the area code. Japan’s mobile number typically consists of more than 10 digits.

To recap, here is how you dial Japan from the US:

  • Type US exit code 011 or just type (+) if you’re using mobile or VoIP,
  • Add Japan’s country code which is 081,
  • Add area code (1 to 5 digits),
  • Add mobile number (10+ digits).

The complete dialing code will look something like this;

+81 44 45189 108153

This is the complete code for how you dial a Japanese mobile phone number from the US.

How to Call a Japanese landline Number from the US?

Calling a landline number in Japan is pretty much similar to calling a mobile number. The difference? Landline numbers in Japan are typically 4 to 8 digits long, while mobile numbers are generally 10+ digits in length.

Dial (+) if you’re making an international call from your mobile phone or a VoIP phone. Dial 011 if you’re using a landline phone.

Step#2: Add country code for Japan

Step#3: Add city/area code

Find the city or area code of your desired destination from Japan area codes available at, and add that area code to the dialing number sequence.
