I was really hopeful this would do something to address Japans convoluted address system, anything really, sort of like Open Location Code is trying but with the backing of the post office.
If you don't know the storied history of an area in Japan it can be nearly impossible to find an address manually. You give someone your address in Japan, they have to either use the internet or ask people in the area to help you find it. Most are not based on streets, they are based on smaller and smaller named subdivisions of a given area.
Alas no, this is the exact opposite of Open Location Code and requires an internet connection to look up. We should be working on something that allows you to find an address on foot without an internet connection!
Japanese addresses are a problem this makes no attempt to fix. Just baffling to me.
