Joao Miyao leads Hiago George 5 wins to 2 across 7 recorded meetings, all of them in the gi except for the most recent one, where the attire is unknown. Every one of these matches came in a final, semi-final, or round robin, which tells you these two kept running into each other at the sharp end of the same light-featherweight brackets. Both compete at Peso Pluma (64,00 kg / 141.5 lbs), and both came up through Cícero Costha's Projeto Social Lutando Pelo Bem, though Miyao now lists Studio 1908.

The two George wins both came on advantages, in finals at the 2019 Abu Dhabi Grand Slam Abu Dhabi and the 2017 Abu Dhabi Grand Slam Rio de Janeiro. That fits a rivalry decided on the margins when it went George's way. Miyao's wins were more varied and more final: three by submission, one on an advantage, and one scored as other. Two of those submissions were the Toe Hold, including their 2015 meeting and again in 2023.

The broader records point the same direction. Miyao holds an 88% win rate on record over 254 matches with a 48% submission rate of wins, while George sits at 78% over 216 matches with a 38% submission rate of wins. Miyao's finishing edge shows up in the head to head, since George never submitted him in any recorded meeting.
