It represents the Tenketsu, something the Hyuuga can affect with their taijutsu But yeah could be a Hyuuga symbol used by the whole village as a sign of respect like the Uzumaki symbol.*sighs* yeah it is. I checked it. But the chakra symbol isn't that thing on his belt. It was even in the uchiha clan's hideout.
It's has something to do with Hyugas for sure.
