Winter in Japan can be surprisingly cold, especially in the early mornings and evenings. While coats, gloves, and hats are essential, many locals rely on a small but powerful item: disposable heat pads, known as kairo.
One of the most trusted brands is Kiribai Kairo, a long-time favorite for keeping hands, feet, and even cheeks warm. My daughter, for example, slips a heat pad into her gloves or pants pocket—and sometimes presses it gently to her cheek on the way to school. It’s a cozy habit that reflects how deeply kairo are woven into daily life in Japan.

Many Japanese women, for example, wear pumps or heels even in winter. To stay warm without sacrificing style, they often slip mini heat pads into their shoes—a clever trick that keeps toes toasty without anyone noticing. Others stick adhesive kairo to the inside of their jackets or on the lower back to gently warm their core.
