A strangle suitcase instrument from Japan (all panel text is Japanese) and probably from the 80s. It was designed for Koto practice and has a few cool features.
I try to demo a few different sounds, and give a feel for the instrument.
A free Battery Kit containing the percussion sounds is available here: http://icebreaker-audio.com/freeware/battery-kits/
