Area Code 1532 – Nemuro, Hokkaido

Geographic Coverage and Administrative Jurisdiction

The area code 1532 is a geographic National Destination Code (NDC) assigned to the Nemuro region in Hokkaido, Japan. This code serves the city of Nemuro and its surrounding administrative areas, including the Nemuro Subprefecture. The region is located on the easternmost tip of Hokkaido, facing the Pacific Ocean and the Sea of Okhotsk. The jurisdiction covers Nemuro City, along with nearby towns and villages such as Betsukai, Nakashibetsu, and Rausu, which are part of the Nemuro Subprefecture.

Dialing Formats and Caller Instructions

When dialing a local number within the Nemuro area, the area code is typically omitted, and only the subscriber number is used. However, for calls from outside the area but still within Japan, the full national format must be used: dial 0-1532-XXXXXX. The subscriber number is six digits long, making the complete national number 10 digits including the leading zero.

For international callers, the leading zero is dropped, and the country code for Japan (+81) is added. The international dialing format is +81-1532-XXXXXX. For example, a local number in Nemuro might be 1532-45-6789, which would be dialed as +81 1532 45 6789 from abroad.

Overlay and Numbering Plan Considerations

Currently, there is no overlay code for the Nemuro area; the 1532 code is the sole NDC for this geographic region. However, as with all Japanese geographic codes, the numbering plan is managed by the Ministry of Internal Affairs and Communications (MIC) and the Telecommunications Carriers Association (TCA). In the future, if number exhaustion occurs, an overlay could be introduced, but at present, 10-digit dialing (including the area code) is required for calls from outside the local area.

Caller Instructions for Local and Foreign Callers

Local callers within the Nemuro area can dial the six-digit subscriber number directly without the area code. For callers from other parts of Japan, the full national number must be dialed, including the leading zero. Foreign callers should use the international format, omitting the leading zero and adding the +81 country code. It is important to note that when calling from a mobile phone in Japan, the area code is always required, even if you are in the same region, unless you are using a landline within the same charging group.

For businesses and individuals in Nemuro, it is advisable to always provide the full national number (0-1532-XXXXXX) on websites and marketing materials to ensure accessibility from anywhere in Japan. For international clients, the +81 format should be clearly displayed.
