Use your slow cooker to infuse the delicate taste of sweetened soy sauce to pork, making for a easy-to-prepare, delicious and economical dish.
Place the pork roast into the bottom of a slow cooker. Pour the tomato sauce, sugar, soy sauce, sake, and garlic into a bowl, and stir until the sugar has dissolved. Pour the mixture over the pork roast. Cover the slow cooker, and cook on Low for 8 to 10 hours.
