Walnut Tree (Japanese: クルミの木 Walnut Tree) is a bakery in the world of Magical Pokémon Journey. Walnut works there with his parents.
While it is primarily known for its bread, Walnut Tree also sells confectionery and other treats as well. Apricot is a frequent customer of the store, attracting Walnut's attention, even though he is initially unaware of her identity.
