A Starfleet vice admiral played by Clyde Kusatsu who commands Starbase 173 at the time of Data's hearing and later sends Picard to the Devron system anomaly.
Admiral Nakamura is a Starfleet flag officer played by Clyde Kusatsu in three episodes of The Next Generation. In The Measure of a Man he commands the newly established Starbase 173 and brings Commander Bruce Maddox aboard the Enterprise-D with the proposal to dismantle Data.
In Phantasms he is in command of Starbase 219 and hosts the annual admirals' banquet, which Picard is relieved to miss when the ship's warp drive fails.
He returns in the finale All Good Things, placing the fleet on alert over Romulan movements near the Neutral Zone and ordering Picard to investigate the anomaly in the Devron system.
