>>144Aria's on the list that's for sure, but have never watched more than one episode.
I think Yokohama Shopping Log counts which I've read and watched, a very comfy show even if the overall world seems pretty bleak (especially when Alpha needs a gun for some reason). I also loved how that manga was around 10 years in length so children grew up into adults.
Not sure of any others pre-2000 though, seems like people just talk about those two when it comes to this genre.
