Prepare the sweet potatoes
Wash and peel the sweet potatoes. Cut into 1-inch thick sticks or bite-sized pieces.
Fry the sweet potatoes
Heat oil in a deep pan over medium heat. Fry the sweet potato pieces until golden brown and tender. Remove and drain excess oil on paper towels.
Make the glaze
In a separate pan, combine sugar, soy sauce, mirin, and honey. Heat on low until the sugar melts and forms a sticky syrup.
Coat the sweet potatoes
Add the fried sweet potatoes to the glaze and toss gently to coat evenly.
Garnish
Sprinkle sesame seeds over the candied sweet potatoes.
Serve
Serve warm or at room temperature as a sweet, crunchy snack.
