Tenshi no 3P!

Update: 3/7/2024
-Added Wagahai wa Inu de Aru: Don Matsugorou no Seikatsu

Update: 1/13/2024
-Added Chou Futsuu Ken Chiba Densetsu, an Anime about Chiba Prefecture and its locations.

Anime that takes place in Chiba Prefecture or uses this place as a motif. May contain Spoilers, so this Stack is marked as such.
Rules:
1) Must have a sufficient amount of screen time in Chiba Prefecture or use the location as a motif, no single episode visit.
-This is the primary reason was to why "Manga Nippon Mukashibanashi"
was excluded from this list as only select stories take place in Chiba Prefecture out of the large pool of episodes. (One story took place in the following locations: Onjuku, Iioka, Nagara, Sōsa and Ichihara, while of the rest that also takes place in Chiba Prefecture has a blank entry)
2) Sorted by the date of first released anime that PRIMARILY takes place in a specific location such as a city. (Not by the stated year the Anime takes place in)
3) To prevent redundancy, we only use the first season.
4) If the entry is blank, its because the Wikipedia page never listed anything such as a city, nonetheless these entries are still Anime that takes place in Chiba Prefecture or use it as a motif.
5) Entries with a location such as a city that does not in real life Chiba Prefecture will be noted. (e.g. Godzilla: S.P)
6) Anime that has listed multiple primary locations will all be sorted together and has the same year rules as point number 2. For example, Dagashi Kashi has multiple listed locations including Chiba Prefecture City, but is not listed alongside other Chiba Prefecture City Anime.
7) The ones from that only appears on the Category pages will be noted. These entries used additional web sources to specify a specific part of Chiba Prefecture such as a city. Though some do not specify a specific location inside of Chiba Prefecture.
