Calling Abroad from Japan, Step by Step
Follow these quick steps to reach any country from Japan, with notes for both mobile and landline numbers.
International Prefix
From a Japanese landline, begin with 010. On a mobile or web dialer, just press the plus sign and it adds the right international access for you.
(Tip: in Intercalling you simply enter + and the country code.)
Country Code
Once the prefix is in, add the country code of wherever you are calling. Think 1 for the USA, 44 for the UK, and 61 for Australia.
Area Code and Number
Finish with the area code and local number. Strip the leading zero off domestic prefixes once a country code sits in front.Example: 03-1234-5678 becomes +81 3 1234 5678
Worked Examples
Calling out of Japan is easy once you drop the domestic trunk zeros. On a mobile or in the browser, a leading + keeps the whole thing simple.
Japan City Codes
Area codes for Japan's largest cities. Calling in from overseas? Drop that leading zero.

| Osaka | Kansai | 6 |
| Nagoya | Chubu | 52 |
| Sapporo | Hokkaido | 11 |

How Mobile Numbers Dial
What to know about Japanese mobile numbers when you call across borders.
Mobile Prefixes
Japanese mobiles usually begin with 070, 080, or 090. From abroad, drop the leading zero and lead with the country code, so it reads +81 90 1234 5678.
Let + do the work
On mobiles and web dialers, open with + then the country code and number. Intercalling reads the + format, so you can paste an international number straight in.
