Crewman Kamata was a member of the crew of the Enterprise NX-01 during its mission in the Delphic Expanse in 2154.

Kamata was killed during a Xindi attack, when the section in which Kamata was present on C-deck decompressed. As that section was inaccessible for a period of time after the attack, Kamata was officially considered unaccounted for, until the crew finally located Kamata's body, along with that of Crewman Jane Taylor.
