|Nakamura developed the time of flight (TOF) experiment device which used ion beams for electric field measurement in space. His sounding rocket experiment on S-510-9 was the first TOF electric field measurement in the ionosphere/ magnetosphere in the world. Thus he is a pioneer of the digital electric field measurement method of the world. Later he designed the electric field detector system (EFD) on Geotail. Many scientists accomplished work to receive high acclaim with Nakamura's measurement device. He himself analyzed the electric field data and particle data from Geotail, and especially on the events of the Pc5 ULF waves, reconnection at the dayside magnetopause. He received NASA group achievement award on his contribution to the magnetospheric science in 1994, as well as ESA award in 2003 on his contribution to Cluster mission.
He designed the the eXtreme Ultra-Violet scanner (XUV) on Planet-B Mars orbiter which was launched in 1998. He succeeded in taking the first EUV snap shot of the terrestrial plasmasphere in the world, thus he is considered as a pioneer of EUV imaging of the planetary plasma.
He received Tanakadate medal from the Society of Geomagnetism and Earth, Planetary and Space Sciences on his work "The study of plasma transport in the terrestrial magnetosphere" in 2002.
He started teaching graduate school student since 1993. Seven graduate students of his school received doctor of science degree from the University of Tokyo, and more than 20 students received MS degree from the University of Tokyo.
