I play and have both instruments but this looks like fun. 2 instruments in one Sanshin & Shamisen
Hey, that’s neat 
It looks so tiny, though, I’d be worried about going full force with a bachi haha
Pretty cool idea. I’d be the one gal who attempts to use it with a bow as a Kokyu though XD
Heeeey, that’s Hamatani-sensei from 3:26 ~ !
Neat.
