Orencio James Virgil "OJ" De los Santos (born February 7, 1990)[1] is a Filipino karate practitioner who competes in kata events.

He follows the shotokan style of karate and also participates in e-kata tournaments, or kata competitions held online since the beginning of the COVID-19 pandemic.

He was about to quit karate until he was inspired by the Philippine national team competing at the 2005 Southeast Asian Games which was hosted in the country.

[2] After taking part in the 2005 Southeast Asian Games as a spectator, De los Santos decided to continue his karate career.

In the domestic level, he competed for his hometown Cebu City at the Philippine National Games for at least six times[2] and won six gold medals.

[3] After his fallout with KPI, De los Santos transitioned to online kata or e-kata and competed in various international tournaments without KPI's endorsement, which meant that the government body Philippine Sports Commission could not give assistance to De los Santos in response to his e-kata feats.
