Hi Mike, welcome ! Unfortunately I don't have an answer on yours. It looks vaguely similar to some Arias with that neck cutaway style, trapezoidal truss rod cover shape and long square neck tenon, but cavity routes differ slightly from any I've seen. The switch, pots, squarish nut profile and pickup cavity shape lean more towards Korean examples, but I can't dismiss earlier Japan builds outright. I haven't come across that headstock shape yet either , so hopefully someone who does recognize it will eventually chime in. Thanks for posting pics + best of luck identifying it.
