The ceiling of a narrow tunnel under a railway line in Nishinomiya, Hyogo Prefecture, is so low that adults must stoop over to pass through. Despite this, what locals have nicknamed the "Manbow Tunnel" remains a busy and vital passageway in daily life. Among people using the tunnel were a woman taking the shortest route to the supermarket, and a family who likes the thrill of this unusual path under the tracks. For three days, we took a closer look at this tunnel and its role in the local community.
