Preheat the oven to 375˚F. Wrap a rimmed baking sheet tightly with aluminum foil. Place a wire cooling rack on top of the foil wrapped sheet tray.
In a large baking dish, mix the granulated sugar, brown sugar, black pepper, and togarashi spice with a whisk or your hands until well blended. Dip each slice of bacon in the sugar mixture, pressing to coat and then gently shake off excess sugar. Repeat with all bacon slices. Lay the bacon on the wire rack and bake for about 20 to 30 minutes until crisp.
