Preheat the oven to 400 degrees Fahrenheit. Place the chicken drumsticks in a deep baking pan.
Prepare the marinade by combining tamari, five-spice powder, honey, garlic, and toasted sesame oil. Pour the marinade all over the chicken drumsticks until they’re all nicely coated.
Once the oven is fully preheated, place the baking pan on the middle rack. Bake for 20 minutes.
Then flip the chicken, and bake for another 20 minutes.
Finally, flip the chicken again once more time, and finish cooking for 10 minutes (for a total of 50 minutes).
Garnish with green onions and serve immediately with rice, tomatoes, and cucumber.
