The subject may be not true.
As far as I know there are no witches in Hirosaki city in Aomori, Japan ..
However, some people may know the animation series called “Flying Witch“ that is the story happening in Hirosaki city.
I have not seen any Japanese animation series are laid in Hirosaki. Since I am outside of Japan, watching this animation reminds me of dear my home town. Scenery, building, strong dialect and food are shown in it.
I watched several episodes on YouTube (you can simply search keywords “Flying Witch” or in Japanese “ふらいんぐうぃっち”) and hit some episodes. They are quite fun storyline and also a lot of unique things in Hirosaki are infused its scenes! I recommend to to watch it if you are looking for some animation series to watch.
The plot from Wikipedia:
The story is about Makoto, a young witch from Yokohama, that moves to Aomori to live with some relatives as part of her training. What follows is Makoto’s daily life as she gets used to her new environment and her relatives and the new friends she makes there are introduced to the customs and peculiarities of witchcraft.
Now they are available in Crunchyroll site.
Because of this animation, Hirosaki is doing lots of promotion with this animation.
I have got a chocolate cake with this 🙂 That’s Taste Great!!
