As a collaborative effort between a leading Japanese industrial robotics company, Kawasaki, and a medical manufacturer, Sysmex, Medicaroid was established in 2013 to develop a Japanese robotic surgical system ( Japan manufactures more than half of the world's market share of industrial robots; however, no surgical robot has come to market. Medicaroid has developed a surgical robot, Hinotori, with a stated goal 'to serve and assist humans, not to replace humans' (

Named after the well known Japanese manga novel of the same name, Hinotori has eight degrees of freedom, easy docking, and a 3D-HD viewer claiming, 'more than full HD resolution'. There are four robotic arms attached to the cart, and the surgeon wears polarized glasses using a semi-open console with a microscope-like ocular lens[4] (Supplementary Figure 2,

In August 2020, Medicaroid received regulatory approval from the Japanese Ministry of Health, Labor, and Welfare for the Hinotori Surgical Robotic System ( As of late 2020, Hinotori remains in the development stages with no published preclinical data and no human clinical data. Medicaroid has made it clear that they intend to enter the US market with their made-in-Japan surgical robot (;
