The label on the back of the grey Speak & Spell proofs clearly its origin.

The inside view of the Speak & Spell (Japan) shows the additional jacks for
an external power supply and the headphone.

The PCB of the Speak & Spell (Japan) is centered around a TMC0271 Microcontroller,
a TMC0281 Voice Synthesis Processor (VSP), two TMC0350/CD2321 and TMC0350/CD2322
Voice Synthesis Memories (VSMs), and a small power supply and 8 character VF-Display.
