9/24 Tatami Day

Tatami Day (Designated because 9/24 is "Cleaning Day." Also, April 29th, "Greenery Day," is also considered Tatami Day due to its color. Established to promote the excellence of tatami as a housing material and floor covering. The word "tatami" is said to originate from the verb "tatamu" (to fold), as they were originally thin mats like "mushiro," "goza," or "komo," which were folded when not in use. Their current form, laid out to cover the floor, dates back to the Muromachi and Kamakura periods.)
