Socks Day (Kutsushita no Hi) — November 11th, Shaped Like the Number "11"

What Is Socks Day?

November 11th is "Socks Day" (Kutsushita no Hi) in Japan, established in 1993 by the Japan Hosiery Association and also known as "Pairs Day." Socks do their job as a pair, and two pairs laid side by side look like "11 11." The association is a trade group of sock makers, and every year on this one day when pairs meet pairs, it encourages people to give socks to someone they care about.

"Pairs Day" and the Idea of Sekku

According to the Japan Hosiery Association, a day when the month and day are the same number, like November 11th, was called a "sekku" in the old Chinese calendar. A sekku marks a turning point of the seasons, when offerings were made to the gods and shared to pray for health. The New Year's osechi, the hina-arare of March 3rd, and the kashiwa-mochi of May 5th all belong to this tradition. So November 11th is treated as the "socks sekku," a day to exchange socks. The association explains that, unlike a ceremonial day such as Valentine's Day or a birthday, this is a day when both people in a pair can be happy at once.

• Established:By the Japan Hosiery Association in 1993. Member companies run campaigns and limited items around this date every year. In 2024, Fukuske, Tabio, Gunze, Okamoto, Atsugi, Naigai, and others put out recommended items
• Origin of the date:Two pairs of socks look like "11 11," and the left-right pair of a sock is likened to pairs of people such as couples
• The argyle legend:The diamond pattern is said to have been devised by a princess of Argyle Castle in Scotland as a gift for her lover, and is presented as a sign of love. A sock book written and supervised by Hiroshi Aramata was also made to mark the establishment of Socks Day

Nara, Japan's Sock Town

Nara Prefecture is Japan's largest sock-producing region. According to the Nara Prefecture Hosiery Industry Cooperative, its sock industry began in 1910 as Western-style dress, which had blossomed in the Rokumeikan era, took root. After nylon began to be produced in Japan in 1951, woolly-nylon socks became a huge hit in place of cotton and rayon, and the prefecture has since accounted for about 60 percent of national production, and its share of production in fiscal 2024 was again about 60 percent. The cooperative also runs a brand project and certifies "sock sommeliers." Looking for the place of manufacture on the label can be part of the fun of choosing socks.

Tips for Marking This Day

• Check your socks for holes and stretched-out elastic, and replace worn ones this time
• Reconsider material and thickness by use: business, sports, and cold weather. In general, cotton absorbs moisture well, wool retains heat, and synthetics such as polyester dry quickly. Thin, snug socks suit business wear, and cushioned ones suit sports
• Follow the care label; turning socks inside out and using a laundry net makes the fabric less prone to wear. Check the label before using a dryer
• Give socks to someone who matters to you. For a coworker or family member, they can be a small sign of thanks. Asking about size and favorite colors beforehand helps avoid a miss

Summary

Socks Day is a day to take a fresh look at the socks we wear every day. Two pairs side by side looking like "11 11" makes it an easy topic for office small talk. Choosing a fresh pair can also lift your mood on the way to work. Socks are practical for warmth and protecting the feet, and also an item for having fun with style. Get your footing right and start work in comfort.
