Uday Raj was named by his cousin who won a game to name him, and chose "Uday" meaning sunrise as it was a sunny day when he was born. He lives in Minotani, Japan with his parents, elder brother and sister, grandmother, and pet dog. Uday enjoys playing golf with his father, jumping off cliffs into the ocean, hiking, and exploring new things with his family and dog, who he likes more than his brother despite being bitten and hit by him.
