As the year ends in less than a month, it’s now ideal for the Japanese to begin osouji—or deep cleaning—in honor of Toshigami, the Shinto God of the New Year.

Traditional brooms were commonly used in Japanese homes. Regular use brought out the natural shine on the mat’s surface, which goes well with soft rush plant tatami matting. And, of course, every broom comes with a dustpan. Harimi are traditional Japanese dustpans made of washi paper stretched over a bamboo strip framework. They’re sealed with kakishibu dye, a persimmon tannin-based water-resistant and bug-repellent colorant. But “sweeping” has a more symbolic significance for the Japanese. Brooms are used as talismans to “brush away” evil spirits, illness, and danger. Many temples and shrines throughout Japan participate in a cleaning ceremony on December 13 to remove physical and mental pollutants that have gathered during the year.

Technology changes and evolves regularly, but tradition doesn’t. It’s rooted in our culture, and no amount of cleaning will be able to “sweep” it away.
