Answer 1

The area code for Billings, Montana is 406. Just so you know, to call to the US, you have to enter {country code} + {area code} + {7-digit phone number}.

The country code of the US is 1, so you would be calling -

1 + 406 + {7-digit phone number}

You might need to dial in your country's exit code before dialing that so Japan knows that you're calling outside of Japan. So according to the website, you would be dialing -

010 + 1 + 406 + {7-digit phone number}
