Geographic Overview
The area code 979 is a geographic National Destination Code (NDC) assigned to the Nakatsu area in Oita Prefecture, Japan. This code serves the city of Nakatsu and its surrounding administrative districts, including parts of the former Chūgoku region on the island of Kyushu. Nakatsu is a historic castle town located on the banks of the Yamakuni River, near the border with Fukuoka Prefecture.

Dialing Formats
When calling a landline number in the Nakatsu area from within Japan, the national trunk prefix 0 is used, followed by the area code (without the leading zero) and the subscriber number. The full national format is 0-979-XX-XXXX. For example, a local Nakatsu number might be 0979-XX-XXXX when dialed domestically. From outside Japan, callers must use the international access code (e.g., 011 from the US, 00 from most countries), followed by Japan's country code +81, then the area code without the leading zero, and the subscriber number. Thus, the international format becomes +81-979-XX-XXXX. For instance, if the local number is 0979-12-3456, the international dialing format would be +81 979 12 3456.
Caller Instructions
For local callers within the Nakatsu area, dialing the 7-digit subscriber number alone may be sufficient if the call remains within the same charging group. However, for calls from other regions in Japan, the full national format 0-979-XX-XXXX is required. International callers should always drop the leading zero and use +81 979 followed by the subscriber number. It is important to note that Japanese landline numbers are fixed at 10 digits in total when dialed nationally, including the trunk prefix and area code.
