I became aware of this #OvertureMaps PR¹ and you can tell that it seems they haven’t read “Falsehoods programmers believe about addresses”².
“All addresses have [...] street, number, [...] postcode.” Good luck recording addresses in Japan!
UPDATE! @jwass2000 (who opened the PR) and @ian (founder of #OpenAddresses) have replied saying that the address schema is intentionally simple at first but will eventually be more sophisticated.
