In the last years of the Meiji era (1868-1912), Abashiri Prison
began to accept inmates with brick-making skills from prisons on Honshu (the main island of
Japan). The bricks fired by these inmates were used to build walls, gates, storehouses, solitary
confinement chambers and other facilities. The solitary confinement chamber shown in the
photo has double doors and no windows. The brick walls are more than 40cm thick. With changes in
the prison rules, the name of the solitary chamber changed from “punitive chamber”
to “disciplinary chamber” and then to “protective chamber”. In the
Meiji era, prison rules specified that any inmate who broke the rules should suffer the stiff
penalties of confinement in a dark, windowless room, reduced meals and self-reflection. The
solitary confinement chamber shown in the photo is likely to have been built to comply with the
rules of the Meiji era.
