Cotton Day (Kotton no Hi)

What Is Cotton Day?

May 10th is "Cotton Day" in Japan. The date comes from a wordplay on the numbers 5 and 10 — "kot (5)" and "ton (10)" together sound like "cotton." The date also reflects the fact that cotton, as a summer fabric, reaches its peak season in stores in May. The day was established in 1995 by the Japan Spinners' Association to promote the appeal and value of cotton and encourage the use of cotton products.

The Background of Cotton Day

Cotton is a natural material that has been used in clothing and household goods for centuries. It's highly absorbent, breathable, and gentle on the skin, which has made it a beloved fabric worldwide. In May, as temperatures rise, summer cotton clothing fills store shelves. The main component of cotton fiber is cellulose, which forms plant cell walls.

The Characteristics of Cotton

• Highly absorbent: Soaks up sweat well, keeping you comfortable.
• Excellent breathability: Resists trapping heat, making it ideal for spring and summer clothing.
• Pleasant to the touch: Its soft feel makes it a common choice for underwear and innerwear.
• Strong: The fiber doesn't stretch easily, is strong, and holds up well to washing.

Fun Facts About Cotton
