It is a humanoid yōkai that appears above roads, and when those that see it look up, the shidaidaka would accordingly grow taller. In reverse, if one looks down it becomes shorter, but if one doesn't look down, it would steadily grow taller.
Therefore, if one ever meets a Shidaidaka, then one must never look up. In reverse, if one looks further and further downwards, the shidaidaka would steadily become smaller, and then disappear. In Sakurae, Ōchi District, Shimane Prefecture, in a place called Kawato, when a shidaidaka appears, one must never look at it from beneath one's thighs.
