Where the Streets Have No Name

Have you ever heard the U2 song “Where the Streets Have No Name”? I’ve always wondered if this was some sort of deep metaphor with a hidden meaning, but on second thoughts, I think Bono was just talking about getting lost in Japan!

If you’ve ever come across a Japanese address before, you’ll know that they’re about as long as an essay, and even more complicated. If you’ve never run into the concept of a Japanese address, it’s about as opposite as you can get from the western addresses we are familiar with.

With the exception of major roads, Japanese streets are not named. Streets are simply an empty space between blocks, they don’t have an identity. Instead, cities and towns are subdivided into areas, subareas and blocks, similar to the insulae system of the Roman empire. It is a completely different, but perfectly valid, system of structuring and organising cities. But to complicate the matter even more, houses within each subarea are not formerly numbered in geographical sequence but in the order in which they were built. It must be a nightmare for their postal workers!

Nippon the subway

For this reason trying to get directions to a location can be a bit of an ordeal! Most people will offer visual landmarks like stadiums, parks, and subway stations such as “at Chūō-dori and Matsuya-dori across the street from Matsuya and Ginza station”, for a shop in Tokyo. In fact, most businesses will include maps on their literature and business cards. But this is by no means unique to Japan, reference points are used in lieu of addresses in other places all around the world, including Costa Rica, Albania and even India.

In Japanese, addresses are written using the complete opposite convention from the addresses we are used to, starting with the biggest geographical entities down to the more specific ones. They start with the postal code (a 7 digit format), followed by the region, city and subarea, and end with the name of the addressee. If addresses are written in English, they start with the recipient’s name and end with the prefecture and postal code.

As interesting or as humorous as these addressing differences may seem, they can have some serious consequences for international data management. So unless you have a wealth of knowledge on the variations in global data at your disposal, you will find yourself forever fighting data fires, and never achieving any level of data quality.
