The Shrine is located southeast of Popla Foothills Skyview Tower.
The Shrine is located inside Tobio's Hollow Cave. The shrine is revealed via the Shrine Quest Legend of the Soaring Spear, in which Link must stand on a pedestal that lights up while he is on it and throw a Zonaite Spear with a wing of some type fused to it, be it a monster part or the Wing Zonai Device, through the lit up circle on the other side of the room. A journal detailing the riddle and two Zonaite Spears can be found close by.
