McDonnell battled back with a series of blows to Kameda to wrestle back the initiative and knock the 23-year-old out of his rhythm.
The Doncaster man finished the fight strongly with a couple jabs in the final round to give him confidence of victory at the bell.
The judges declared McDonnell the winner by a narrow margin as three recorded scores of 114-113 improved the 29-year-old's record to 26-2-1 and handed Kameda the first defeat of his career.
