When Fender first starting doing business in Japan, they partnered with FUJI-GEN. That's who made the early Squiers, and the early MIJ Fender from the 80's and 90's. When that partnership dissolved... Fender started using Tokai to build the guitars and the designation changed from MIJ to CIJ. Although Tokai put(s) out a brand of their own causing some confusion, but they are really just a guitar plant that builds guitars to spec for the company's that order them. A Japanese made guitar under ANY brand (Fender, Epiphone, Ibanez, PRS, etc... etc..) would be made in one of the "plants". Fuji-Gen and Tokai were/are two of the biggest and best. To answer your question directly... YES, Tokai Gakki certainly built great guitars in that era. TBH, I don't know an era where they didn't. They are one of the high end builders that produces guitars for ANY brand, to the specs they are given.
