Yakusoku (Lead song)

Yakusoku (Lead song) refers to the title track on the debut single of the Japanese idol group Sakurazaka46. Released on December 9, 2020, "Yakusoku" (約束), meaning "Promise" in English, served as the group's introductory statement following their rebranding from Keyakizaka46. The song’s lyrical content explores themes of hope, rebirth, and looking towards the future, reflecting the group’s own transition. It's performed by the main lineup members and features choreography distinctive from Keyakizaka46's darker and more rebellious image. The center position for "Yakusoku" was held by Yurina Hirate, although the single was released after her departure from the group. The track received significant attention and achieved considerable commercial success upon its release, solidifying Sakurazaka46's initial presence in the Japanese music scene.
