On September 1, 1949, Kihachiro Onitsuka founded Asics in Kobe, Japan, marking the beginning of a footwear revolution that would eventually lead to the company's global success.

In 1950, Mr. Onitsuka is inspired by vinegared octopus to create suction cup basketball shoes, improving stopping and starting performance by deepening dimples on the sole to resemble octopus suction cups.

In 1952, Kazuma Usui founds Usui Meriyasu Works, which later becomes JELENK Co., Ltd., starting as a manufacturer of sportswear and baseball stockings under the KU UNION brand.

In 1953, a marathon shoe is released by the company, showcasing advancements in footwear technology for long-distance running.

Onitsuka Co., Ltd merged with GTO Co., Ltd., and Jelenk Co., Ltd. in 1977 to form ASICS Corporation. This merger marked a significant milestone in the history of the company, solidifying its position in the sportswear industry.

In 1993, shoe designer Toshikazu Kayano drew inspiration from the stag beetle's hard exoskeleton to create the Gel-Kayano running shoe, combining support and nimbleness.

By 2006, Asics had achieved significant growth with 171 billion yen in net sales and 13 billion yen in net income, expanding its product range to include sportswear and various sports shoes.

Asics purchased the Swedish outdoor brand Haglöfs for ¥11.4 billion. This acquisition expanded Asics' product range.

On October 4, 2011, Asics announced that it would be the new official kit manufacturer for the Australian Cricket Team, taking over from the previous manufacturer, Adidas. This sponsorship deal expanded Asics' presence in the sports industry.

Asics introduced the 'Asics Tiger' lifestyle brand, which drew inspiration from the company's designs from the 1970s to 1990s.

Asics acquired the fitness app Runkeeper, further diversifying its portfolio and entering the digital fitness market.

In March 2017, employees working at an Asics factory in Cambodia fainted due to thick smoke in the workplace. Asics responded by promising to improve workers' awareness, health and safety training, and enhance the air ventilation system in the factory.

In March 2021, amid concerns of forced Uyghur labor in Xinjiang cotton production, Asics announced that the Australian Olympic Team uniform would not contain cotton sourced from Xinjiang. This decision aligned with other Western clothing brands expressing similar concerns.

In fiscal year 2022, Asics achieved ¥484.6 billion in net sales and ¥19.9 billion in net income. The company's revenue was diversified across various product categories and regions.
