Yoshio Saito, 85, is one of the last remaining chimney sweepers for Japan’s traditional public bathhouses. In Tokyo’s Sumida ward, he continues to climb rooftops and clean chimneys by hand, preserving a vanishing trade. As environmental regulations and rising fuel costs push bathhouses to abandon chimneys in favor of gas or electricity, Yoshio’s work has dwindled. Despite his family’s concerns, he refuses to retire.

After the devastating Noto Peninsula earthquake, Yoshio meets 32-year-old Kenta Shinya, the young owner of a damaged bathhouse in Suzu City. With little experience and few resources, Kenta hopes to revive the bathhouse, which once served as a vital community space. Moved by Kenta’s determination, Yoshio decides to take on one final job—restoring the chimney of Amida-yu. As he prepares for the journey north, this becomes not just a repair mission, but a symbolic handover of craft and spirit between generations.
