Area Code 1352 – Yoichi, Hokkaido

Geographic Overview

The area code 1352 is a geographic National Destination Code (NDC) assigned to the Yoichi region in Hokkaido, Japan. This code covers the city of Yoichi and its surrounding areas, including the towns of Niki and Furubira, all located along the western coast of Hokkaido facing the Sea of Japan. The region is known for its scenic coastline, fishing industry, and historical significance in the development of Hokkaido.

Dialing Formats

When calling a landline in the Yoichi area from within Japan, the national trunk prefix '0' is used, followed by the area code and the subscriber number. The complete national dialing format is: 0-1352-X-XXXX (where X-XXXX represents the 5-digit subscriber number). For example, a local number might be 0-1352-5-1234.

For international callers, the Japanese country code +81 is used, and the leading '0' of the area code is dropped. The international format becomes: +81-1352-X-XXXX. For instance, if the national number is 0-1352-5-1234, the international dialing format would be +81-1352-5-1234.

Calling Instructions

• Local callers (within Yoichi): When dialing from another landline within the same area code, you may need to include the area code depending on the specific local dialing rules. In Japan, even local calls often require the full number including the area code, but some areas allow abbreviated dialing. It is recommended to always use the full national format (0-1352-X-XXXX) to ensure connectivity.
• Long-distance callers within Japan: Dial the national trunk prefix '0', then the area code 1352, followed by the subscriber number. Example: 0-1352-5-1234.
• International callers: Dial your country's international access code (e.g., 011 from the US), then Japan's country code 81, then the area code without the leading zero (1352), and finally the subscriber number. Example: 011-81-1352-5-1234.

Administrative and Regulatory Notes

The Yoichi area code is part of Japan's geographic numbering plan, administered by the Ministry of Internal Affairs and Communications (MIC) and allocated to Nippon Telegraph and Telephone (NTT) East. As with all geographic codes, numbers under 1352 are tied to physical locations and are typically used for fixed-line services. However, number portability allows users to retain their numbers when switching providers, but the geographic association remains.

There are no overlay codes currently in effect for this area, meaning that 1352 is the sole area code for the region. Callers should be aware that when dialing from mobile phones, the same national format applies, but mobile users may need to include the area code even for local calls, as mobile networks do not automatically add the area code.
