A 25-year-old woman named Misaki is preparing for her upcoming marriage. While rummaging through some old belongings, she stumbled upon an ancient photograph taken at Tokyo Station and a broken pocket watch from her late father who used to work there. Despite her recollection of her father as a strict man, the photo revealed a smile that she had never seen before. In pursuit of repairing the pocket watch, Misaki discovered that there was once a watch store located within Tokyo Station.
Toki wa Meguru was created in celebration of the 100th anniversary of Tokyo Station. The goal of the short anime is to show the history of the station through animation and music.
