A Yamaguchi-based company, Ogori Shōji (which, until then, had been operating men's clothing shops called "Men's Shop OS") was founded in March 1949 in Ube, Yamaguchi.
On 2 June 1984, it opened a unisex casual wear store in Fukuro-machi, Naka-ku, Hiroshima, under the name "Unique Clothing Warehouse". Initially, the brand was going to be registered as a shortened contraction of "unique clothing". However, in 1988, during administration work in Hong Kong for registering the brand, staff in charge of registration misread the "C" as "Q", and that is how the brand name was born. Tadashi Yanai then changed the store name to "uniqlo" across Japan. In September 1991, the name of the company was changed from "Ogori Shōji" to "Fast Retailing", and by April 1994, there were over 100 Uniqlo stores operating throughout Japan.
In 1997, Fast Retailing adopted a set of strategies from American retailer The Gap, known as "SPA" (for specialty-store/retailer of private-label apparel), meaning that they would produce their own clothing and sell it exclusively. They engaged the retail brand consultancy, CIA, Inc./The Brand Architect Group, to guide the company through the realization of this strategy, including consulting on merchandise, visual merchandising and display, store design and a new logo designed by Richard Seireeni and Sy Chen of The Brand Architect Group's Los Angeles office. Uniqlo had begun outsourcing their clothing manufacturing to factories in China where labour was cheap, a well-established corporate practice. Japan was in the depths of a recession at the time, and the low-cost goods proved popular. Their advertising campaigns, clothing quality and new retail layouts also proved fruitful.
In November 1998, it opened their first urban Uniqlo store in Tokyo's trendy Harajuku district, and outlets soon spread to major cities throughout Japan. In 2001, sales turnover and gross profit reached a new peak, with over 500 retail stores in Japan. When Uniqlo decided to expand overseas, it separated Uniqlo from the parent company, and established Fast Retailing (Jiangsu) Apparel Co., Ltd. in China. In 2002, their first Chinese Uniqlo outlet was opened in Shanghai along with four overseas outlets in London, England.
Uniqlo entered the Chinese mainland market in 2002. As of August 2021, there were 832 stores in China, including in Beijing, Guangzhou, Chongqing, Chengdu, Nanjing, Ningbo, Shanghai, Shenzhen, Shijia, Tianjin and Xi'an. "Given the population of 1.3 billion, I think we can go for about 3,000 stores," Fast Retailing chief Tadashi Yanai told The Nikkei in 2020, indicating plans to continue opening locations in the world's most populous country.
As of 2021, Uniqlo had 15 shops in England. Ambitious expansion plans in the early 2000s were reversed, with 16 shops being closed in 2003, including those in Manchester, Coventry, and Leicester. Uniqlo opened a brand new shop in Manchester on Market Street in April 2019.
In September 2005, Uniqlo opened its first United States store in the Menlo Park Mall located in Edison, New Jersey. In November 2006, Uniqlo opened its first global flagship store in the SoHo fashion district of Manhattan, New York City. New fashion designers joined the store's team to boost and rebirth fashion concepts catering to the US market.
On 1 November 2005, Fast Retailing transferred the business related to clothing manufacturing and retailing to Sun Road Co., Ltd., a wholly owned subsidiary that operated golf courses through a company split (absorption-type split), and became a holding company. On the same day, Sun Road changed its name to Uniqlo Co., Ltd.
2005 saw more overseas expansion, with stores opening in the United States (New York City), Hong Kong (Tsim Sha Tsui) and South Korea (Seoul), their South Korean expansion being part of a joint venture with Lotte. As of year-end 2005, in addition to its overseas holdings, Uniqlo had around 700 stores within Japan. By 2006, sales were $4 billion. By April 2007, the company had set a global sales goal of $10 billion and a ranking among the top five global retailers, joining what at the time was Gap, H&M, Inditex and Limited Brands.
The German fashion designer Jil Sander joined Uniqlo in 2009, and was appointed creative director of the brand's menswear and womenswear – as well as launching a new label, +J collection, which won the 2011 Brit Insurance Design Fashion Award.
Fast Retailing signed a design consulting contract for Uniqlo products with fashion designer Jil Sander in March 2009. Shiatzy Chen was approached by Uniqlo to produce a capsule collection of ready-to-wear pieces to launch in November 2010, while Asia's largest Uniqlo store outside Japan opened its doors in Kuala Lumpur in the same month.
As of 2022, Uniqlo had 27 stores in Singapore. Uniqlo opened its first store in Singapore on 9 April 2009 in Tampines 1, which has been closed down on 17 January 2021 and instead, a new store at Tampines Mall was opened on 5 February 2021 and has the similar format as Bugis+, ION Orchard, JEM, Orchard Central and Plaza Singapura which has two floors, one for men and one for women. The first Global Flagship Store opened on 2 September 2016 at Orchard Central replacing 313 @ Somerset. Numerous expansion plans were unveiled in 2020 and Uniqlo ION Orchard and Plaza Singapura, were also heavily expanded and is called "Uniqlotown" for Orchard Road.
On 2 September 2009, Fast Retailing announced that the company would target annual group sales of 5 trillion yen (approx. US$61.2 billion) and pretax profit from operations of 1 trillion yen (approx. US$12.2 billion) by 2020. This means that the company is aiming to become the world's biggest specialty retailer of private label apparel with a continuous growth rate of 20% per year. The figure breaks down as one trillion yen from Uniqlo's Japan business, three trillion yen from its international business, and one trillion yen from "Japan-related and global brand business." The company's international business target breaks down as one trillion yen in China, one trillion in other Asian countries and one trillion in Europe and the United States.
