Quick answer: dial format
From United States, a traditional phone starts with 011 (international exit), then 81 (country code), then the rest of the number.
Leave off the trunk 0. Mobile examples begin 070, 080, or 090 nationally and become 70, 80, or 90 after +81. Geographic examples are not one length: 03-1234-5678 becomes +81 3 1234 5678, 075-123-4567 becomes +81 75 123 4567, and 011-234-5678 becomes +81 11 234 5678. The 011 at the start of 011-234-5678 is Japan's trunk 0. On a call from the United States or Canada, the exit code 011 comes before 81. These examples are not assigned to a city.
In Ringvoo, enter +81 and the same national digits. Do not add 011 in front of the plus.
