Nobody makes a show about a train station and a sleepy kid just to sell commemorative merchandise. Dededen treats the Seibu Shinjuku Line like it matters, like the small rituals of commuting are worth five perfect minutes of your time. You watch it on the train itself, which means the show is talking directly to the person sitting next to you, about the exact ride you're on right now.
Dededen is a slice-of-life special created by TMS Entertainment in partnership with Seibu Railways to mark two milestones: the studio's 50th anniversary and the rail company's 100th. Its lead, Amoru Tokorozawa, is shown going about ordinary days alongside the railway. The project runs to five very short episodes of 75 seconds apiece. They were shown on the display screens inside Seibu trains and on screens at major stations from February 23 to December 31.
