Inami's team is developing a series of technologies rooted in the idea of "jizai", an Japanese term that he says roughly denotes autonomy and the freedom to do as one pleases.
Inami says he was inspired by traditional Japanese puppetry and a quasi-horror short story by novelist Yasunari Kawabata about a man who borrows a young woman's arm and proceeds to spend the night with it. A promotional video for the "Jizai Arms" shows two ballet dancers performing a routine with robotic arms protruding from their backs and torsos - human and machine moving in concert. The dancers ultimately embrace, cyborg arms included.
