 All observations showed a classically shaped bimodal lightcurve with a high brightness amplitude between 0.52 and 0.75 magnitude, which is indicative of an elongated, non-spherical shape.According to the survey carried out by the Infrared Astronomical Satellite IRAS, "Furusho" measures 9.07 kilometers in diameter and its surface has an albedo of 0.37.In 2017, a study dedicated to Mars-crossing asteroids by the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer determined a diameter of 10.04 kilometers with an albedo of 0.21.
