With the right Japan phone number and service provider, you can easily achieve those goals. So, it’s important to know which phone numbers are available in Japan and how they meet different communication needs.

Telephone Numbers in Japan

The Ministry of Internal Affairs and Communications regulates Japan’s telecommunications, including phone numbers. Japan’s numbering plan details specific telecom offerings like message dial, mass calling, fixed-line, and unified number services. Additionally, this plan lists various numbers available and their general formats.

You’ll need to dial the proper Japan phone number format to connect calls successfully. The country code (also called dial-in code) for Japan is (+81) and the trunk prefix is (0). Japan phone numbers are typically 9-10 digits and include:

  • Toll free prefix or area code (usually 2-3 digits in length)
  • Exchange number (2-4 digits)
  • Subscriber number (4 digits)

If you’re calling Japan from outside the country, you’ll need to include an exit code. This is also referred to as a dial-out code or international number prefix. The international prefix depends on the country you’re calling Japan from.

Types of Phone Numbers Available in Japan

There are different phone numbers available within the Japan phone number code — including mobile, local, toll-free, and special numbers. Let’s take a look at each one individually.

Local Japan Phone Numbers

Local phone numbers, also known as geographic numbers, begin with a distinct code for specific cities or areas. These numbers allow you to establish a local presence, connect with customers in high-target areas, conduct local market research, and much more. You can get local phone numbers in many major cities such as:

  • Tokyo (03)
  • Osaka (06)
  • Kyoto (075)
  • Sapporo (011)
  • Hiroshima (082)

The digit length of Japan’s area codes depends on the size of the designated area — the bigger the city, the smaller the code. For example, Tokyo’s (Japan’s largest city) area code is (03). Whereas Yamaguchi’s (a smaller Japanese region in terms of population and area) area code is (0839).

Local Japan phone numbers are available to those located in Japan and businesses overseas. Businesses located outside of the country can purchase a local Japan number from a virtual number provider. Virtual local numbers enable your business to scale globally without relocating or opening new offices. So, your company avoids increased overhead costs — making it a more cost-effective solution than traditional landlines.

Mobile Japan Numbers

Japan mobile numbers start with (090), (080), or (070) codes that include the country’s trunk prefix. Most of Japan’s large population own smartphones or mobile phones, which typically include SMS and instant messaging features among other capabilities.

Mobile Japan phone numbers help businesses create an omnichannel service by offering SMS contact methods as an alternative to calling. So, your business appeals to different consumer preferences, making your business more accessible and easy to reach.

Japan Toll-Free Numbers

Toll-free numbers in Japan typically start with (0120), (0531), or (0088) prefixes. Japan toll-free phone numbers work identically to all other toll-free services. They are completely free for customers to call and easily recognizable. Additionally, these numbers allow you to expand to new markets and build an international business network cost-effectively.

Japan toll-free numbers are not accessible to customers in other countries since they are country-specific. However, your business doesn’t need to be located in Japan with a virtual toll-free number. You can simply forward your incoming toll-free calls to any of your global offices. This makes it easy for your business to connect with international customers and business contacts as well as offer 24/7 customer support services.

Special Numbers in Japan

Special numbers in Japan guide callers to emergency, operator, directory, and other phone services. These numbers are only 3 digits long, making them easy for callers to remember and dial quickly. Special numbers are usually created and managed by each country’s telecom regulator or governing entity.

Here are some examples of Japan’s special phone numbers:

Emergency Services Operator and Special Services
110 – Police 100 – NTT operator
118 – Maritime emergencies 115 – Telegram services
119 – Ambulance, Fire brigade 117 – Speaking clock
