Bra Day (Burajā no Hi)
OtherWhat Is Bra Day?
Every year on February 12th, Japan observes "Bra Day." This anniversary was established by Wacoal, a major Japanese women's lingerie maker, and is registered with the Japan Anniversary Association. It's a day to reflect on the history and role of the bra and to encourage people to think more carefully about wearing underwear that truly fits their body.
The Origin of the Anniversary
Bra Day commemorates February 12, 1914, the date on which a patent for what is considered the prototype of the modern bra was filed in the United States. The patent was filed by American socialite Mary Phelps Jacob, and her design drew attention as a new alternative to the corset for supporting the bust.
The Prototype Bra
The design described in that 1914 patent was remarkably simple — just two handkerchiefs tied together with ribbon. Compared to the rigid, restrictive corsets that were standard at the time, it was praised for being far more comfortable and practical, and it laid the foundation for the bras we know today.
The History of the Bra
The basic concept of supporting the bust with cloth or bands dates all the way back to antiquity. Corsets dominated from the medieval period through the early modern era, but in the 20th century, as women entered the workforce in greater numbers and fashion evolved, the modern bra became widespread.
The Spread of Bras in Japan
Bras became commonplace in Japan after the 1950s, as Western-style clothing spread in the postwar period. From the 1970s onward, designs diversified rapidly, with bras developed for specific purposes such as posture correction or sports.
The Purpose of Bra Day
- To raise awareness of the history and role of the bra.
- To encourage people to reconsider their bra size and how they wear it.
- To spread accurate knowledge about body and bust health.
- To encourage healthier, more comfortable habits through underwear choices.
