It is even more complex than that: within a neighborhood you have "chome", then blocks, then buildings. All three levels are numbered chronologically and don't follow any kind of logical order. Oh, and streets don't have names. Honestly, I don't know how people did before modern navigation systems.
So yeah, this system looks like a godsend, I want to try it as soon as possible.
* I don't know if there is a translation for this word.
Indeed - at least now you can enter the property address (e.g. a four-digit number followed by a dash and another number, as in this small town) into google maps and it'll show you where it is. Not long ago it was more like driving in the general direction while hanging on the mobile phone and trying to agree on a landmark (e.g. a 7/11 or a tower or an office building) while trying to find the place. Before mobile phones? Well, there's this big big sign in a park near the town center, and on that you can find family names on a kind of map.. of course that had this assumption that Nobody Never Moves. So, no, I don't know how people did this in the past.. "Where the Streets Have No Names", the U2 song. I wouldn't have imagined, but that's how it is.

The good old: ask a local about it. Nowadays people seems so against just stopping a random passerby to ask them a question. (obviously not feasible with the huge amount of deliveries we do today but back then it would have been reserved for the very rich or rare occasions)
