Now in each town among their differences are festival differences. Besides the cooking festival that both towns have there are many others that you can only enter depending on the town you live in.
Konohana Town has the following festivals which are kind fun. The Flower Festival, Children Day, the Crop Festival, Bug Catching Festival and Fishing Contest. Theres also the Moon Viewing and Snow Festivals.
Now Bluebell town to my seems to have the more interesting festivals. Theres the Spring Harmony Day, the Animal Festival, Bare-handed Fishing Contest, Star Gazing Festival, Pumkin Festival, and the Winter Harmony Day and Starry Night Festivals.
Okay when choosing the town your going to live at the beginning of the game theres some differences that you should keep in mind. As you know Bluebell is centered around raising animals. So in Bluebell you can only get the following the Pet Playpen, Bee Hive(s), Yarn Maker, Cheese Maker, and Drink Maker.
In the town of Konohana your mainly raising crops so the things that you can only get while living in that town are Seed Maker, Flour Mill, Rice Paddy, Fermenter, and lastly my favorite the Fish Pond.
Inside your house on the left side of the screen is a counter. On the counter you'll see some stuff like your calender. Next to that you should see what looks like a model wagon. Just click on that and you should be brought to another screen where you can change your cart.
