Dialing Japan from Honolulu, Step by Step
Here is how the standard international format works when you ring Japan from Hawaii, and how the same number drops straight into low cost Intercalling browser calling.
US Exit Code
Start with 011. From a mobile or over VoIP you can simply enter the plus sign in its place.
Japan Code (+81)
Follow it with +81, the country code that routes your call into Japan.
