There's oh, I don't know, all the hundred plus year old shrines, Hiroshima Atomic Bomb dome. That's all I will list for now, because I'm assuming your post is a joke
No not a joke. I wouldn't go near a shrine just like I wouldn't go near a church. I just googled the Atomic Bomb Dome, crumbling ruins are not what I think of when I think of Japan. Surely there are places to go that are more... modern?
