Why anime in general feature school life that is rather easy-going and fun.
But that's not what it seem to happen in the reality at all, same for the usual over caring and loving family when's there's a big issue with families's relationship in Japan.
Why such a gap between reality and fiction ?
I feel like this cannot be the only answer.
I mean, every single matter about this subject is avoided in shows.
thats Because THERE ARE loving and caring families. Just as anywhere else.
As for school life, compared to Japanese corporate slavery it should look pretty ideal.
>easy-going and fun
You have your answer, OP.
Because in Japan after school your life is practically over so looking back to it from your office cubicle it seems like joyfull time of life by comparison.
And family is the only easy way out of it, because fuck having to talk to strangers that might require effort.
This is ofcourse, a very broad generalization but it does ring true in most cases to have a culture form around it.
