Japan Postal Codes

Japan, known for its advanced infrastructure and efficient systems, has a robust postal code system that helps streamline mail sorting and ensure timely delivery. The Postal Code System in Japan is essential for navigating the country's diverse regions, from urban cities to rural areas.

Structure of Japan's Postal Code
Japan's postal code is written as XXXX-XXXX, where:

• First three digits (XXX): Represent the region, city, or district. This part of the postal code is typically used for sorting mail at a regional level.
• Last four digits (XXXX): Represent the specific area, locality, or post office. This further narrows down the delivery location, ensuring precise delivery to the intended address.

For example, 100-0001 is the postal code for Chiyoda, Tokyo:

• 100 refers to Tokyo's region.
• 0001 specifies a particular area within Chiyoda.
