Poke holes in both sides of the chicken with a fork. Heat vegetable oil in a pan and place the chicken skin-side down. Cook until the skin is crispy.

Flip the chicken over, cover with a lid, and cook for 7–8 minutes until cooked through.

Mix the soy sauce, mirin, sugar, sake, and ginger together. Add to the pan and coat the chicken with the sauce.

To serve: Place rice in bowls, top with nori, sliced chicken, and sprinkle with sesame seeds. Add a soft-boiled egg and vegetables on the side.
