Enkanomiya is a strange area in Genshin Impact as it is part and not part of Inazuma at the same time. This means things are much different in the Forgotten Region. One of the very first things you'll notice is that there isn't even a Statue of Seven to be found, which means Kokomi's descendants didn't worship the Raiden Shogun.
Enkanomiya, like Dragonspine, has no eyes but rather has its own system in place using seals. Seals are scattered on the card instead of the oculi and will make the same noise as an Electroculus when it appears, and a small emblem will be displayed on your mini-card.

Despite the lack of an oculi, Enkanomiya keeps the electro seal in place. Opening the chests will yield Electro Seals, which can then be exchanged at the Sacred Sakura Tree on Narukami Island for rewards. The rarer the chest you find, the more Electro Seals you can expect to earn from it, just like in the rest of Inazuma.
