Area Code 1395 – Esashi, Hokkaido

Geographic Overview and Administrative Jurisdiction

The +81 1395 area code serves the Esashi region of Hokkaido, Japan's northernmost main island. Esashi is a town located in the Hiyama Subprefecture, on the western coast of Hokkaido, facing the Sea of Japan. This area code covers Esashi town and its surrounding administrative districts, including parts of the former Esashi District. The region is known for its historical significance as a former fishing port and its scenic coastal landscapes.

Dialing Formats and Number Structure

When calling an Esashi landline from within Japan, the trunk prefix '0' is used, followed by the area code (without the country code) and the local subscriber number. The national dialing format is: 0 1395 X-XXXX. The local subscriber number typically consists of 5 to 6 digits, making the total national significant number (NSN) length 10 digits when including the area code. For international callers, the country code +81 is used, and the leading '0' is dropped. The international format is: +81 1395 X-XXXX. For example, a local number in Esashi might be dialed as 0 1395 2-3456 domestically, and as +81 1395 2-3456 from abroad.

Caller Instructions

Local callers within the Esashi area code region can often dial the 5-6 digit subscriber number without the area code, depending on the specific telephone exchange and carrier configuration. However, for clarity and to avoid misdialing, it is recommended to always include the area code when dialing from a mobile phone or from outside the immediate area. Callers from other parts of Japan must dial the full national number: 0 1395 X-XXXX. International callers should replace the leading '0' with the country code +81, resulting in +81 1395 X-XXXX.

Overlay and Numbering Considerations

As of the latest ITU-T and Japanese Ministry of Internal Affairs and Communications (MIC) data, there is no overlay code for the Esashi area. The 01395 area code is exclusively assigned to geographic fixed-line services in this region. However, with the ongoing migration of fixed-line services to IP-based networks, some numbers may be routed over VoIP infrastructure, but the geographic significance remains for emergency services and number portability.

For businesses and residents in Esashi, it is important to note that the area code is an integral part of the national numbering plan and must be included when receiving calls from outside the region. The region's remote location means that reliable landline connectivity is essential for local commerce and public services.
