If it's weekdays... everyone IS at school or work.
Also in Japan, there are laws about posting others' faces online without permission, so Japanese creators often will only put content without people online, as it is easier that blurring out their faces, asking for permission, or facing repercussions.
Are you telling me in a city of 35M, that nobody even seniors is having a day off to enjoy life ?
I think its sad. There must be millions of seniors who have worked very hard and almost NONE - yes not a joke, can afford to have a day off ?
The streets around the central part of Tokyo near the big train station or square or the palace or near the green walking/bicycle paths are all almost empty.
Empty here means there are barely 1 or 2 people just walking and enjoying their life. The background near the big buildings and so on are filled with people rushing to work but NOBODY looks like they are actually smiling and enjoying life in their grand city.
The same is true of many other cities and towns around Japan. Its hard to find anyone when clearly there are thousands somewhere nearby.
