Yashica (well-known for it's photocamera's) merged with Kyocera in 1983 and, to my knowledge, only manufactured one MSX computer.
Probably because Kyocera was too busy developing Philips' VG-8020 MSX computer! ;)
This Yashica YC-64 is a pretty standard MSX computer, 64 kB RAM, 16 kB VRAM and nothing fancy.
Here's another pic of the Yashica YC-64, this time in color.
I found it on the net.
