K.Yairi has a long history since 1935 and is still making guitars in Japan today. You can find historical details:
Like most Japanese constructed guitars, the build quality is exceptional. There is real care taken with the important details of bracing and set up. This guitar sounds amazing and the neck is as straight as the day it was made with no dipping to the top. It has a generous round sound with the low body pitch. The action and neck profile ensures comfort and easy playing. Of course, being half a century old there are marks to the top and dings to the back of the neck but no cracks.The guitar compares favourably with anything on the market priced £1750 upwards and as such will be a very reasonable purchase.
Includes hard case.
