You'd probably want to avoid citing Japanese TV shows as reference. They are all fake and completely scripted/heavily edited from start to finish.

In Germany school literally recomends for kids to go alone to school from first grade. First graders also went alone from school to afterschool activity.

7 years old navigating streets is not as much rarity as Americans think. And it used to be completely normal too.

True, but younger kids walk around by themselves (mostly in groups) all around Japan. Japan is a weird case though where the cities are safer than the countryside.

Not saying it's not true. Just saying taking a Japanese TV Show as a proof has 0 credibility.

Yes, it doesn't have credibility for what actually happens, but it can have credibility for what standards people / pop culture apply.

(And that's what my original comment talked about. Also, it's just a cute show.)
