"Sazae-san spacetime", by the way, seems to be pretty much the Japanese name for Comic-Book Time. The trope page even says as much.
For reference, Sazae-san has been airing in Japan since 1969 and has something like 7000+ episodes. It continues to be set in 1960s Japan.
What are you talking about?
That's what we call "SA◯◯E-SAN SPACETIME"!
What is it all of a sudden...
The Village humans seem to grow up normally.When I came here to Gensokyo, my body stopped aging.It bothers me that no matter how many years pass, nobody seems to age.I wondered what you were going to say, but that's it?
Even though we're all humans
Serious book?
...Well, this is a serious book, so jokes aside.
*aside*
Kanako-sama says it's because the "goddess" part of "living goddess" is stronger than in the Outside World.Hahaa, you just now noticed?
