The NEC PC-8001A was the first computer system to be mass marketed in Japan in 1979. In physical design it's almost a clone of the Radio Shack TRS-80 Model 1, introduced two years earlier; both have the CPU fully contained within the keyboard; both use the Z-80 microprocessor, and both use external expansion interfaces. The NEC is a more sturdily built machine than the Radio Shack; where the TRS-80 uses plastic, the NEC uses metal. The NEC is also much faster, at a full 4 MHz clock speed, and has color graphics.

Here's a shot of the complete PC-8001A system with I/O expansion chassis, dual floppy drive enclosure, and NEC monitor:
