The immersive walking tour experience “Tokyo Metro Maintenance Division: Lost and Found Section” will begin for a limited time starting Friday, November 20, 2026.
Participants take on the role of part-time workers in the Tokyo Metro Maintenance Division’s “Unidentified Lost Items Unit.” Their mission is to return the “unidentified lost items”—mysterious entities that occasionally appear underground—to their rightful places.
However, this job comes with mysterious rules that must be strictly followed. Participants will walk through actual stations, interact with cast members, and deliver all the mysterious lost items to their destinations.
Changes from the First Installment
Following the popularity of the first installment, “Escape Window,” the stations and areas serving as the setting have been revamped. With an entirely new story and production, the experience is designed to be enjoyable even for those who haven’t experienced the first installment. In addition to everyday underground spaces such as passageways and plazas, the experience will also utilize special areas within station premises that are normally off-limits to the public.
Interactions with the cast are also central to this experience. Depending on what participants ask and how they respond, their own deductions and decisions will influence the story.
The specific location of the event is undisclosed and will be revealed only to ticket holders. The meeting point will also be indicated on the ticket.
