I'm not sure what you mean by "highlight", but I remember reading somewhere that Japanese people are usually very nostalgic of their school years, though I don't remember if there was an explanation given for it.
My personal opinion is that the Japanese society is very demanding for adults, and people recall these years as less burdensome. Perhaps this is the same everywhere?
