Akira Hirota was a 23rd century Human male. By the late 2250s, Hirota was a command division commander serving in Starfleet, assigned as first officer aboard the USS Constitution. In 2257, Hirota joined the Constitution's senior staff in a small gathering in the ship's lounge as they welcomed aboard new helmsman and second officer, James T. Kirk. Hirota remained aboard the Constitution for some time after Lieutenant Kirk had departed from the ship. (TOS - My Brother's Keeper novel: Enterprise)
