Season both sides of the chicken with a pinch of salt. In a saucepan, combine all ingredients for the Teriyaki Sauce. Reduce heat to low and simmer for 10 minutes.
Heat a nonstick skillet over high heat while you wait. Cook the chicken thighs skin-side-down until they are well browned and cooked through. To get a crispy skin, pan fry the skin. Then turn off the heat and take the chicken out. Let cool.
Cut the chicken thighs in half and then drizzle the teriyaki glaze over it. If desired, garnish with sesame seeds. Serve immediately with warm, steam rice.
