Yea i have noticed that most Japanese anime, manga, video games and other Japanese media focus plenty of friendship, family, never giving up, life and the world being like an adventure filled with miracles and dreams coming true, hope for the future and other very positive things so yea the Japanese obviously loves that stuff and yea Japan seems to have WAY more suspension of disbelief than people got over here nowadays because people over here cant separete fiction from reality anymore.
Here in the west people seems to have a way more negative view on people and the world and people want everything to be as realistic as possible and want the characters to act and work just like real life people would act in these situations and most western people nowadays seems to have completely lost there suspension of disbelief and thinks everything that is not the classic and old stuff from fiction that we have seen hundreds of times before is stupid, weird and should not be taken seriously.
I know most people hate it but i personally love the focus on friendship, family, hope, never giving up and all the other stuff i mentioned before because i love the positive and happy feelings it gives me and it sure feels way better than how negative most media here in the west i s nowadays where almost everything must be dark, terrible, violent and have little hope.
Its only stuff made for young children that are not like that nowadays over here.
And that the Japanese got so much more suspension of disbelief than people got in the west is probably why they create new, original, different and creative things all the time and we over here almost never creates anything new and different anymore.
