Digitown is the main hub of The Denpa Men 2: Beyond the Waves. Some notable structures are listed below.
Antenna Tower, Denpa Men House, PC, Spirit Shrine, and Hero's House.
Shop, Museum, and the Gardener's Shed. Once you unlock the Gardener's Shed, you will acquire another plot of earth in which to grow more plants and the Gardener Willow will move in to teach your Denpa Men how to water the flowers. This means that you no longer have to go on The Denpa Men 2 and water the flowers yourself as your Denpa Men water them for you, and it's all free.
