Mix the soy sauce, mirin, sake and sugar in a small bowl.
Pat the chicken dry, prick the skin a few times with a fork and sprinkle both sides with the salt.
Heat the oil in a large frying pan over medium heat and cook the chicken skin side down for 7 minutes, until the skin is golden and crisp.
Turn the chicken and cook for 5 minutes more, until the center reaches 74C.
Wipe the rendered fat out of the pan with paper towels.
Pour in the sauce and simmer for 3 minutes, turning the chicken, until the sauce is thick and glossy.
Slice the chicken, spoon the glaze over it and serve with rice.
