In a bowl, mix the cream and goat cheese with a fork until thoroughly combined. Mix in the wasabi sauce, soy sauce, ginger, garlic and sesame oil. Fold in a 1/2 cup of green onions.
Transfer the cheese mix to a sheet of plastic wrap. Form into a ball. Use more plastic wrap as needed. Refrigerate for at least 1 hour.
Remove the cheese ball from the plastic wrap and sprinkle with the remaining green onions as well as the nori and sesame seeds. You can also mix the green onion, nori and sesame seeds in a bowl and roll the ball in the mixture.
Place on a platter and serve with rice crackers.
