japan has one person every  - 12 meters on residential area - 50 meters if including all roads, forests and wilderness areas, most of which can not be used by people daily, so it's not an effective area if these were deer statistics, hunters would lose their minds and call for military weapons. japanese people have to negotiate or even fight for every little space they have against others. they live in artificial light all day because they can't even be near windows during work.
