Dialing
How to call Japan: step by step
The full sequence is: exit code + 81 + local number (minus the leading 0).
- 1
Dial your exit code
From the United States and Canada that is 011. From most of Europe, Asia, and Africa it is 00. On any mobile you can simply press and hold 0 to get a + instead, which works from anywhere. - 2
Dial 81
81 is the country calling code for Japan. It never changes and it is the same from every country in the world. - 3
Drop the leading 0
Numbers written for domestic use in Japan start with a 0. That is a national trunk prefix, not part of the number; remove it when dialling from abroad. 3 1234 5678 is what you dial after +81. - 4
Check the time first
Japan is on JST (UTC+9, no DST). Business calls placed outside local working hours are the most common reason an international call goes unanswered.
Worth knowing
Japanese mobile numbers start 070, 080, or 090. Japan's own IDD prefix is 010, not the 00 used across most of Asia.
