Hi Mike,
Your first step should be to compare the headstock of your Tokai with the pictures at the bottom of this page:

Mainly your looking at headstock logo (spaghetti, block, script, etc), model (Springy sound, Goldstar sound, etc) and shape (exact Fender or pointed).
Also look on the back of the guitar's neck for a small oval numbered sticker and on the underside of the pickups for any markings.
Cheers
James
