Jayden Daniels has a Japanese flag on his helmet to honor his heritage. Specifically, the flag pays tribute to his maternal great-grandmother, who was Japanese. Daniels began wearing the Japanese flag decal on his helmet during the 2025 NFL season to show love and respect for that part of his family background. This addition reflects a broader NFL policy allowing players to display country flags on their helmets to celebrate their heritage year-round starting in 2024. Daniels, who previously only had the American flag on his helmet, chose to add the Japanese flag to recognize this important cultural connection.
