SHOWA Corporation headquarters in Gyoda, Japan.

The company was founded in 1938 as Showa Aircraft Precision Works.[3] In Japan's drive to develop its military capability in preparation for World War II, Showa supplied aircraft suspension and landing systems to various aircraft manufacturers.[citation needed] Banned from developing or manufacturing aircraft systems after the war, Showa entered the car components industry, using its aircraft knowledge to develop specialist suspension products for motorcycles made by the new company Honda. The relationship between Showa and Honda developed over the years, with Honda Racing Corporation accounting for more than 50% of Showa's business.[citation needed]

In 1950 Showa acquired Rikuo Motorcycle, which made licensed versions of Harley Davidson motorcycles in the 1930s and 1940s.[4] Rikuo brand lasted until 1962. Showa has since become OEM supplier to Harley Davidson.[5]

Showa has overseas facilities in Brazil, Canada, China, India, Indonesia, Mexico, Spain, Taiwan, Thailand, United Kingdom, United States and Vietnam.

Showa was an official IndyCar Series shock absorber supplier from 2007 to 2011. Showa remained IndyCar Series shock absorber supplier since 2012 but only for Honda-powered teams.

In October 2019, Showa began to be merged into Hitachi Automotive Systems as their supplier of steering and suspension components, along with Keihin and Nissin Kogyo, also partners of both Honda and Hitachi.[6] The merger was completed in January 2021,[7] with the resulting parts supplier known as Hitachi Astemo (Japanese). The Showa brand continues to be used within this structure.
