The game takes place on an island in the middle of the sea, which can be inhabited with various Miis created from the built-in Mii Maker or transferred through wireless from a Wii console. Their appearance, personality, and voice can be customized. Once a Mii is created, they will move into their own apartment on the island, allowing them to explore the island and its various facilities. As more Miis are added, more facilities and activities are unlocked, and the Miis may even become friends with each other, hanging out in their apartment or outside.

Inside of the city hall, there is an option to see a character trait chart. All of your Miis will be organized by their personality. It makes it easy to see which characters will be good as friends or not.

Miis can also be interacted with in their apartment, allowing the player to give them food, clothes, or an interior for their apartment. Depending on how much they like it, the Mii's happiness will go up. When it reaches a certain point, the Mii will level up, allowing the player to give them a level-up gift, such as a phrase or song as a reward. If the Mii is asleep, the player may have a chance to view a dream, leading to a bizarre mini-game, event, or activity and be able to draw on their face, though it is not permanent.

At certain times, the player can witness events, such as Street Live at the fountain and Question at the Question Hall.
