These are the brushes that touch the world's faces. Kumano, a small town in the hills of Hiroshima, produces eighty percent of all the brushes made in Japan—the brushes for calligraphy, and the brushes for cosmetics that makeup artists prize across the globe. Walk into any high-end cosmetics counter, anywhere on earth, and there is a good chance the finest brushes were made in this single mountain town. You align the hairs and bind them, gathering hundreds of individual tips into one brush, a maddeningly precise handwork that demands a patience most of us cannot imagine. The fingers of artisans in this remote valley sustain a quiet share of the world's beauty—every brushstroke of foundation, every line of a master calligrapher, drawing on the skill of a place most people have never heard of. To make even one brush here, gathering and aligning and binding the delicate hairs, is to glimpse the staggering care behind an object you would otherwise never think about, and to hold, in a single slender brush, the labor of a town that has perfected the smallest of things.
