Description

Located in the working-class streets of Koiwa in Edogawa Ward, Tokyo, Koiwa Industrial High School—known simply as "Kōkō" (工高)—has earned a reputation that extends far beyond its classrooms. To outsiders, Kōkō was a rough industrial school. To those who passed through its gates, it was a place where character was forged as surely as steel.

Growth

Growth history is still building. We hold one measurement for this entry. A trend needs at least two, taken days apart — so this will fill in on its own rather than being estimated. We do not publish numbers we have not measured.
