Wash sweet rice, and set aside leaving it in a strainer.
Soak dried shiitake in water for 15 minutes. When softened, squeeze out water and slice thinly. Cut carrots into thin matchsticks. Thinly slice green onions diagonally. Cut pork into small strips.
Stir-fry all with sesame oil in a frying pan. Season with soy sauce, oyster sauce, sugar, and salt.
Put the rice in the bowl of the rice cooker and add enough water to reach the line for 2 cups of rice (or mixed rice). Then, take out 3 tablespoons of water. Top the rice with the cooked vegetables and pork.
Change the setting on the rice cooker to "sweet rice" or "mixed rice," then turn it on. When the rice is finished cooking, mix it with a spatula.
