Kenwood was born in December 1946 in post-war Japan, the company’s founders are considered to be Kasuga Nakaichi, his brother Jiro, brother-in-law Hideo Nakano and uncle Hisao. Considering that all the founders are united by ties of kinship, they subsequently chose a name for their business – TRIO. During those years, the national economy was suffering from the terrible consequences of the Second World War and was in the process of industrial and economic recovery. Among the most popular electronics products of the time were AM tuners, as well as other national interest dissemination components and radio broadcasting and sound reproduction components.


Post-war Japan had little time for music. But everyone wanted to listen to the news, so the relatives decided to start building their business on radios. On December 21, 1946, in the city of Komagan, which is located near Nagano, they registered their first company – Kasuga Radio Co. Ltd – Kasuga Wireless Electronics Corporation. Initially, the company was engaged in technical research in the field of radio broadcasting and radio electronics.

The company’s founder, William “Bill” Kasuga, was the first of a generation of Japanese Americans. Being well versed in Japanese and English, Kasuga volunteered for the United States Army as a translator during World War II. After the war, Kasuga taught Japanese, but quickly realized that teaching was not his strong point. One of his friends offered him a job at a company called A&A Trading Co., which imported Japanese-made electronics for RadioShack and was looking for a manager who spoke both English and Japanese well. During his work, Kasuga established good connections with one of the suppliers of RadioShack, a Japanese manufacturer of high-quality audio.

At this time, Trio Corporation management is looking for a way to sell its products directly to American consumers. The entrepreneurial-minded Kasuga was convinced that he could do a substantially better job of selling Trio Corporation’s products than their established competitors in the United States. While seeking investment, a mutual friend connected Kasuga with George Aratani, a wealthy entrepreneur who founded Mikasa & Company, who agreed to provide financing for Kasuga’s venture. Along with Yoshi Nakase, they decided to start a new company that would be the exclusive importer of Trio Corporation products to all other countries.

At that time, Japanese industrial goods had a reputation for very low quality, much like we now have very low prices for Chinese-made goods. But Kasuga has strong faith in the products of Trio Corporation and decides to create a new American Name that will truly resonate. He described the origins of Kenwood as being a combination of the American name “Ken”, which has been tested and proven acceptable to American consumers from the well-known name “Kenmore Appliances” and “Wood”, referring to a well-known place also associated with to Hollywood. The company’s office was located in the area where the famous Hollywood vineyards grew.
