- acoustic guitars
Yasuma Musical Instrument Company was established in 1950 in Nagoya by Kimihiko Yasuma. Yasuma made guitars, mandolins and ukuleles. The guitars most commonly seen are Martin style dreadnought acoustics and may be branded "K Yasuma & Co", Aanton or Angelica. In the 1970s Martin won a copyright infringment case against Yasuma and as a result many Yasuma guitars imported into the USA had to be destroyed. Yasuma carried on for a while after this lawsuit - but had to alter their dreadnought design.
