Tokyo Weekender offers 47 Anime for 47 Prefectures.
Tochigi
One part of the film 5 Centimeters Per Second takes place at Iwafune Station in Tochigi Prefecture. It also shows landscapes of the prefecture, such as Mount Iwafune.
Gunma
You Don't Know Gunma Yet's whole plot is to shatter negative stereotypes about Gunma as we follow a protagonist from Chiba who moves to the prefecture.
What a perfect introduction to Anime! This has me thinking of doing the same for England: "48 Unsettling Memory-Holed Vaguely Pagan Childrens' Books for 48 Counties" has a nice ring to it.
