The 18-year-old then built on the advantage in the next two rounds, stretching the lead to 10-4 against the Russian Youth Champion, who could score just one point in the second and third rounds.
Nanao went for an all-out assault in the final round, scoring five points against his opponent's one to round off his campaign with yet another dominating display.
Cuba topped the medal tally with four gold, a silver and a bronze.
The traditional boxing powerhouse finished the event with 40 points and a points-per-boxer average of 3.6.
