Heat the oven to 375°F. Line a rimmed baking sheet with parchment paper.
In a large bowl, combine the ground turkey, cooked rice, egg, green onions, 1 teaspoon of the grated ginger, garlic, 1 tablespoon of the tamari, and the sesame oil. Mix gently until combined, taking care not to pack the mixture tightly.
Shape the mixture into a compact loaf on the prepared baking sheet. Bake for 25 minutes.
While the loaf bakes, stir together the honey, rice vinegar, remaining 1 tablespoon tamari, and remaining 1 teaspoon grated ginger in a small bowl.
Brush the glaze over the meatloaf. Return it to the oven and bake for 15 to 20 minutes more, until the center reaches 165°F.
Sprinkle the sesame seeds over the loaf and let it rest for 5 to 10 minutes before slicing.
