Suziki Nagoya Suzuki was established in 1887 by founder Masakichi suzuki ( died 1944 ). Nagoya Suzuki first started making stringed instruments like the violin , oud , lute etc. In approx 1911 Masakichi Suzuki made the first Japanese domestic guitar available to the public , the Masakichi Suzuki No.1.

When Masakichi Suzuki died in 1944 ( the end of occupied Japan ) Nagoya Suzuki was then inherited by Umeo suzuki ( eldest son ). Kikuo was made president of the brother company Kiso suzuki est1951 ( although i have found evidence of pre 1950 made Kiso Suzuki guitars ) and another son Shinichi Suzuki founded the Suzuki violin and guitar methods .

Kiso suzuki were tasked with making Suzuki OEM branded guitars ie. Kansas , Oakland , Takeharu , Hillbilly, Holly , Famous , Sonoro, Thomas , Tomson , Maxx , Sunrise , Jason ,Tthunder , J Watson and Co , and to fill orders by other well established brands like Fernandes, Ibanez , Calace , Shinano , Aria , Zen-on ,Bbluebell along with Tama and Bluebell factory ( Fujigen )
