Complete Naomi's quests. One of them will require you to purchase a new territory containing a Wondershop.
After purchasing the territory, help Naomi finish constructing the Wondershop. Thanks to your help, she will always consider you her favorite customer!
You can purchase the territory earlier, but you can only start building the Wondershop when Naomi gives you the quest.
How do I gain access to the Wondershop?
