Everyone who watch けいおん!! (K-On!!) sure know about the school they all study in.
Yep, it's call 桜高校(Sakura High School).
You sure have known how the corridor, staircase, building, even the old statue and the most important, their music room looks like... Especially the stage...
What if, all you saw in the anime is real?
I'm not joking, all are in actual world. In 滋賀県 (Shiga Prefecture), there is a 73-year-old school called 豊郷小学校 (Toyosato Elementary School).
