The Korean joint venture between Yoon Deok-byeong and Yakult Honsha was established in 27 November 1969 under the name () The company created and started selling domestic yakult in 1971 to negative reception in the early days, due to the lack of knowledge regarding lactic acid bacteria. At the time, there  was speculation about the product, due to popular belief that Lactic Acid was harmful to the body. Despite this, Yoon carried on with the sales, starting with an aggressive marketing campaign, including a "free tasting campaign" for the public, a door-to-door sales campaign by hiring housewives (who came to be known as Yakult Lady/auntie), who knew the local neighborhood and knew the locals. This marketing campaign resulted in a major success, with sales increasing to a million bottles sold per day by 1977. In 1976, the company founded the Korea Yakult Research Institute, a research institute that  is notable for researching and inventing the Bifidobacterium HY8001 probiotics/lactobacillus, resulting in South Korea depending much less on imports from the United States, Europe, Japan, and multiple countries for lactic acid products.The research institute also has a library of over 4,000 types of bifidobacterium strains, with 139 patent registrations and 56 patented strains, and has developed 22 lactobacilli for product application since its founding. It is the birthplace of multiple products that are sold by Korea Yakult. In 1987 the company began distributing its products overseas, under the brand name Paldo. In 2012, Paldo Co. Ltd. was launched  as an independent subsidiary of Korea Yakult. In 2019, Korea Yakult changed the name of the "Yakult Lady" (), which is a symbol of the company, to "Fresh Manager" () to mark the 50th anniversary of its foundation. In 2021 March 29, Korea Yakult declared that they are renaming their business to hy, Ltd. due to their interest in expanding their portfolio in the distribution sector after a shareholder meeting the day before.
