Trim excess fat from chicken legs. Sprinkle salt lightly over chicken, and leave for 10-15 minutes.

Remove any moisture with paper.

Heat oil in a heavy frying pan, add chicken skin side down, and cook until browned. Turn over and cook the other side until browned.

Remove any oil in the pan with a paper towel. Add water, sugar, Soy Sauce, and Sake and stir. Cover and cook for 15-20 minutes. Remove the cover, and add Mirin to the sauce. Reduce until the sauce is thick if not thickened already. Coat the chicken with the sauce well.
