The upcoming handheld release will feature a garden centre, thrift store and a 24-hour museum, complete with an exhibition room and a gift shop, reports Famitsu (via Nintendo Life).
Users will be able to visit a fully-fledged shopping mall, as well as a raccoon housing project run by Tom Nook.
Animal Crossing 3D also introduces swimming, extra village and household customisation options and the chance to dress up in Legend of Zelda costumes.
It contains StreetPass functionality, enabling players to view houses and towns from other users.
The game will launch during the first half of 2013, according to Nintendo's Satoru Shibata.
The delay is to ensure that the game reaches the high level of quality associated with Nintendo products.
