I am currently only 10 episodes in and I think I am falling in love with this show the more episodes I watch of it. The show aired back in 1986 and as far as I know it's still going strong. It's about a little girl who lives with her parents named Maruko-chan who shares a room with her sister in rural Japan going about her daily life.
The show is meant for children and each episode tries to teach you some kind of lesson but I am quite sure that even now older folks in Japan to this day watch it from time to time. What really got me hooked initially was how fluid the animation was despite being drawn in a very simple format.
I will try to describe a single episode in the hopes of getting some people interested in it.
Episode 3 "Today is Sensei's Home Visit"
Maru-chan walks home with her friend who complains to her about home visits that teachers tend to do and upon arriving back at her house she noticed that her mother came very prepared for this day making sure to straighten out the house before the teachers visits and asks Maru-chan to go back to her room and clean it up because he will be also inspecting her room.
Instead of cleaning her room Maru-chan decides to bag up all of the mess in her room and asks for her grandpa to look after the stuff until the teacher is gone but when the teacher arrives he doesn't go past the entrance of the house saying that this is enough for him and quickly leaves after a short talk with Maru-chan and her mother.
After leaving Maruko-chan goes to the kitchen and sees sweets that her mother prepared for the teacher that was coming but since he already left she couldn't let them really go to waste, could she, and instead gobbles all of them up with some tea. Then she goes back to grandpa to grab all of her stuff that she took out of her room and returns it back into place making a mess of the room again.
Then it turns out that there is another visitor at the door which was the teacher of Maru-chan's sister which goes past the entrance way into her room and sees the mess that her room is and everyone looks completely shocked with a complete freakout from Maru-chan's sister, her mother quickly takes the teacher to the kitchen for the snacks that she had prepared but as Maru-chan ate it there was none left for her.
The episode ends with Maru-chan thinking she can escape this situation by repeating "I don't know" to her mother.
