Some Suzuki History
Suzuki Guitars have been around since the early 1900's. Instead of just one "Suzuki" guitar manufacturer, but there are actually three different Japanese companies that have manufactured guitars under the name of Suzuki to the present time - Kiso Suzuki and Nagoya Suzuki, which are related, and Suzuki Manufacturing Co (modern company, started by Manji) which has nothing to do with the original Masakichi Suzuki factories. But Kiso and Nagoya have a common ancestry.
Suzuki Manufacturing Company used to make guitars with the label M Suzuki (Manji Suzuki) but today is known as just 'Suzuki.'
Kiso Suzuki manufactured guitars in the region of Kiso-Fukushima, Nagano prefecture.
Nagoya Suzuki manufactured guitars in the region of Nagoya Japan.
They manufactured about the same number of models as Kiso, and many of their model numbers are the same. But each had different brands and labels, but both are well-liked by owners of their guitars
Masakichi Suzuki was the original founder of the 2-Suzuki companies (not Suzuki Instrument Mfr Company.). He started making violins in 1887 and became well-known in a short time - because of a combination of good timing and quality.
He made guitars starting in the early 1900's, and early models are pretty rare.
In the 1880s, he started to manually produce and sell violins. He founded the Suzuki Violin Factory in 1900. Nagoya became the manufacturing center of string musical instruments.
The Second World War
There was 'one' Suzuki company before the 2nd World War. After the war, a entity created by the US and allies called GHQ (for General Headquarters) dismantled some parts of 'Imperial' Japan and some companies were closed or restructured. In Suzuki's case, the company was separated into - the Suzuki Violin Company, changing to the Kiso Suzuki Violin Company (run by one of Masakichi's sons Kikuo) and the Suzuki Violin Manufacturing Company came to be called the Nagoya Suzuki Violin Company (run by another one of Masakichi's sons, Umeo).
Where Are They Now?
Masakichi's son Shinichi started the well-known Suzuki Method

Another contributing factor to the world-wide success of the Suzuki Violins is the famous Suzuki Method education system. Shinichi Suzuki, the younger son of Masakichi Suzuki, developed this method.
