For real. It seems MUCH more likely that this is simply the shape that these trees grow in. It's even easy to believe that they grow in this type of shape AND the direction it bends is determined by the wind. But it seems very very unlikely that this type of tree is normally a typical tree shape but has oddly wound up in this shape because of especially strong winds.
And i don't understand why people have to make things up in their titles. It would've gotten nearly as much upvotes if it was just titled "sideways tree" or something.
Krummholz trees are trees that have been shaped and scoured by the wind, its definitely a thing. Hard to say for this one, though. Looks a little too healthy and full to be Krummholz.
This tree absolutely does not grow into this shape naturally. Look at the trees in the background. It's a lovely niwaki. The style is to shape the tree to mimic natural phenomena, which this does well, but it's been shaped with artistic intent. This long, arched style is common for framing doorways.
