The keycaps look suspicious. Integrated LEDs and strange rectangular cutouts could point to a Fujitsu Peerless board. The ferrite core on the cable is a bit unusual, I've got one as well on my Fujitsu Peerless board (Epson). Also, kyocera are Japanese, so it might be a Fujitsu Peerless board after all. But!
It's flat. That's quite unusual for a Fujitsu Peerless board, they're usually curved. Get the model number. If it's a Fujitsu Peerless, you'll know instantly.
