Collecting vintage Japanese guitars is a hobby, my favorites are Greco but I also have Fernandes, Hohner, Tokai, and Epiphone guitars.
Here are some links to vintage Japanese guitar website.
Probably the best vintage Japanese guitar catalog source ever
Very cool MIJ website, lots of information on brand names used
Fernandes catalogs and other cool stuff
A side topic to the Les Paul forum, lots of cool guitars
Facebook group all makes and models
If it's not an Ibanez built in1972-75 it's not a true 'lawsuit' guitar
A HUGE list of 'badge' names used by Japanese guitar builders / factories
