Endless Days is a song written by Sakura Yamamoto.

Sakura Yamamoto is a member of the Culinary Team at the Federal Food Plant in Hope. She has been making music in her spare time since she was very young and composes her own pieces, which she performs regularly at Hope's Federal Hostel and Saloon. This includes the song Endless Days, with which she poetically describes life in the Habitual Belt. Through employees of the Federal Courier Service, the song spread to the other reservations. It is one of the most frequently played songs in the Habitual Belt's Federal Saloons, along with the now anthemic folk song “A home, A hope.”
