I don't know if some of the listed guitars are indeed valuable.
This is one of the most frustrating questions from the MIJ collector.
As I've read many different guitar collector/enthusiast forums and spoken to local guitar dealers, it's clear that the layperson has little to no idea who made their badged guitar from the 1960-1980 period, also known as the MIJ golden age of guitar manufacturing.
People often make the mistake of citing the American or European importer as the 'maker' of the guitar, when in fact several Japanese manufacturers were producing badged guitars out of their plants and shipping them to America and Europe to sell.
Japanese manufacturers made multiple badges at the same plant, many of whom resemble each other closely.
Some manufacturers merged or changed hands over the years which added to the confusion, sometime merging with another maker, only to pick up their name later. Listed below are the major manufacturers, known badges and suspected badges to the best of my knowledge in written and list form to make it easy to find out !
In some cases a manufacturer would farm out production to various manufacturers, making it still more difficult to know who made the guitar in your hands. In some cases I won't know because the badge you have may be extremely rare and virtually unknown to even seasoned collectors.
Parts from other guitars would be used in the making of a particular badge for a period of time because it was all the manufacturer had to hand...which doesn't always help in identifying a maker. This page is a work in progress and as new information is revealed it will be added to the list. And just a quick note: I do not buy or sell guitars.
And sometimes, the guitar which is supposed to be an MIJ guitar is actually made elsewhere (Korea, Indonesia) because production was moved during this period in history. I have no idea what any given guitar from this period would sell for.
Since then, Atlansia has continued to produce cutting-edge guitar designs in Nagano, Japan.
The company did not make any other badged guitars other than namesake Atlansia.
Chushin is still in operation today in Nagano, Japan and does business with guitar giant Fender.
