The name Wacoal comes from Wakō Shoji (和江商事), the original legal business name (which meant harmonizing (
wa, 和) with
Kōshu (江, short for
Ōmi Province where founder Tsukamoto spent his childhood). Adding "forever" (
aru, 留) in 1957, the brand was formed. In 1964, Wacoal established the Human Science Research Center to conduct
scientific research on women's beauty, health, and bodies for product development. In 1985, Wacoal launched in
America. To encourage potential customers to purchase the new brand despite the higher prices than its competitors, Wacoal's fit experts partnered with sales associates in
department stores across the country to educate consumers about the fit and quality of Wacoal products. In 2009, Wacoal launched b.tempt'd, an intimate apparel brand aimed toward younger consumers. In 2012, Wacoal acquired the Eveden Group, a UK-based lingerie manufacturer founded in 1920, bringing the full-figure brands Freya, Elomi, Fantasie, and Goddess under its corporate umbrella.
