Those things in Japan, I think they're called Kotasus? They look quite beautiful.
As for cozy, it's driving down a city at night, when it's rainy, and there's reflections of lights on the road, raindrops dripping on the car's windows.
I find being undercover while it's raining very comfy
Can't find pics, but sitting on the porch under a canopy, listening to the rain fall on the leaves, cover, and deck is so nice
Rain on the window while falling asleep, too, of course
