This is a store used as a filming location for the movie "Kyo no sora ga ichiban suki, to mada ienai boku wa" (based on the novel by Jarujaru Fukutoku). I came here for a pilgrimage to the sacred site, but it was calm and the grandmother running it was lovely and nice.

Found it! 📽️ I had a hunch it should be a kissaten near Kansai University and searched for it. I want to go!
