How to reach it
Finish the four Regional Phenomena, then report to Purah at Lookout Landing.
Hyrule Castle. Follow Zelda’s trail into the castle and defeat Phantom Ganon at the Sanctum. Back at Lookout Landing, Purah starts Find the Fifth Sage.
Kakariko Village. Talk to Paya under one of the ring ruins, Ascend into the ruin and photograph the stone slab inside, then bring the picture to Tauro for translation.
Dracozu Lake. From Popla Foothills Skyview Tower head southeast to Dracozu Lake and meet Tauro inside the Zonai ruins. Using the riddle, collect every piece of the Charged set nearby, then offer a Zonai Charge at the ruins near the lake’s tail.
Thunderhead Isles. Return to Popla Foothills Skyview Tower, launch, and glide south until you are over the isles.
Find the chamber. Keep south until you spot a chamber with a shrine inside, then look for the rails beneath it and glide down to the island closest to them.
Build a T-sled. Assemble the nearby wooden platforms into a capital T, attach a fan facing away from the chamber, and set the sled on the rails with the stem between them.
Ride and Ascend. Start the fan, ride until you are directly under the chamber, then Ascend through its floor and examine the shrine to unlock it.
Joku-usin Shrine is a conductivity exam: the room has a metal floor, the shrine hands you a Shock Emitter, and the rest is arithmetic. Getting to it is the longer half.
1. Prepare the Shock Weapon
Take the entrance weapons. Short Circuit confiscates your inventory. A Long Stick and a Wooden Stick by the door are all you get.
Run to the Shock Emitter. Sprint to the back of the room, near the altar chamber, and Fuse the Shock Emitter to the Long Stick.
Your gear is taken: grab the Long Stick and Wooden Stick by the door, then run to the Shock Emitter at the back and fuse it. Screenshot (cropped) from 100% Guides

2. Shock the Constructs on Metal Floor
Use the floor. Lure as many Constructs as you can onto the central metal platform, then swing the shock spear at any one of them. The current spreads through the metal and hits every Construct standing on it; most go down to a single shock.
Mop up. Pick off whatever survived one at a time. If the shock spear breaks, fuse a Construct drop to the Wooden Stick and keep going.
