Frequently Asked Questions
What makes a Japanese address format different?
Japanese addresses use the large-to-small system: postal code, prefecture, city, district (chลme), block (ban), and building number (gล). Street names are not used in standard Japanese addresses โ instead, areas are divided into numbered blocks. The 7-digit postal code uses the format "NNN-NNNN".
