This is a Corral puzzle.
Unless I’m not looking in the right places, this type of puzzle seems to be very rare outside of Japan (I have no idea about inside). That’s better than others like Country Road though, which I’ve never seen. All the more reason to make them and post them. I would give a rough difficulty estimate, but I have no idea what the common techniques for this puzzle are. I always seem to solve these in completely different ways. I do not think this one is easy though.
