Addressing Mail to Japan

Sending something to Japan can be challenging when it comes to addressing your parcel. It is very different from what we are used to in the United States both in language and in how the address is set up.

Most Japanese roads have no names. Japan uses district, division, and block names to narrow down building locations instead of numbers and road names (as the United States does). In addition, most areas number buildings according to their construction date rather than their geographical location. So, the addressing could be difficult when shipping to Japan.

The official language in Japan is Japanese. But English is also commonly spoken and understood. So, you can write addresses in either Japanese or in English. The way it would be written, however, depends on what language you choose.

Addressing Mail to Japan

When Writing Address in Japanese






  • Line 1: The postal code is written in the first line, along with the symbol of the postal code.
  • Line 2: Following the city, village, ward, etc., the address should contain the name of the prefecture and the block. Separated by dashes, these numbers identify the subarea, block, and building numbers of the address. There will be a dash added to the address if the address includes an apartment number.
  • Line 3: The third line contains the name of the person you’re sending your mail to. The last name should be written first, then the first name, and then the title; all three things are separated by commas.
  • Line 4: This last line would contain the country name which in this case would be Japan (日本).

When Writing Address in English


Mr. Haruto

Dia #189

  • Line 1: In English format, line 1 contains the name of the addressee that is, the person you’re mailing to.
  • Line 2: Line 2 is for the building and apartment number. Your destination address may or may not have an apartment number. If it has, mention it after the name of the building. If not, just mention the building name.
  • Line 3: Now comes the address. Three numbers, separated by dashes, should appear at the beginning of the address, indicating the subarea, block, and building number. The following information should be included after the address number: the subdivision, ward, city, or village.
  • Line 4: After the address, the postal code has to be mentioned. Here, prefecture would be mentioned along with the 7-digit postal code.
  • Line 5: The last line, line 5, contains the country name. As we’re shipping to Japan here, ‘Japan’ will be mentioned in line 5.

Final Verdict

Usually, the deliveries are not late than expected, but sometimes, due to customs delays, they might be a little late. So, if you’re shipping anything internationally, keep a fine margin of 3 to 4 days.
