Missing Takeda Castle Ruins really stings for a ruins enthusiast - I mean, they call it the "castle floating in the sky" for a reason! Built in 1411 and left to slowly crumble until the 1970s restoration, it sounds like exactly the kind of atmospheric spot that makes you feel like you've discovered something special.

The whole setup is perfect for that mystical castle vibe - perched up high where it catches the morning mist just right, especially in autumn when it literally looks like it's floating on clouds. They say sunrise in October and November is when the magic really happens, with the castle seeming to hover above a sea of clouds.
