Combine cream cheese, sour cream and Kewpie mayonnaise with spices and lemon juice and whip until smooth. Add capers, crab, and ¾ cheese and mix by hand. Place in shallow baking dish, top with remaining ¾ cup cheese, and bake in 350 degree Fahrenheit oven for 25 minutes or until warm and bubbly. Serve with baguette slices, crackers, on top of steak, or just eat by the spoonful.
