This shop in Harajuku has a huge selection of Evangelion goods spread over over 2 floors. Clothes, home accessories, figurines, food and more! There is also a Art wall which is covered with Evangelion sketches, posters and other art. You’re allowed to make photos of all the products and goodies inside the store, but sadly you’re not allowed to make photos of the Evangelion Art Wall.
This shop has moved to Ikebukuro and is now located inside Ikebukuro Parco Buidling, which can be reached by taking the northeast exit of Ikebukuro Station.
