Rinse the rice under cold water until the water runs clear. Combine rice and water in a rice cooker and cook according to the manufacturer's instructions.

In a skillet over medium-high heat, add the ground beef and cook until browned, breaking it apart with a spatula.

Drain excess fat if necessary. Add soy sauce, brown sugar, sesame oil, garlic, and ginger. Stir to combine and cook for another 3-4 minutes until heated through.

Serve the cooked rice in bowls, topped with the ground beef mixture. Garnish with sliced green onions and sesame seeds.
