Stir the wasabi and soy sauce into the reduction in the pan. Over low heat, gradually whisk in butter one cube at a time allowing the mixture to emulsify. Be careful not to let the mixture boil. When all of the butter has been incorporated, stir in cilantro, and remove from heat. Pour into a small bowl, and set aside.
Heat a large skillet over medium-high heat. Brush tuna steaks with olive oil, and season with salt and pepper. Place in the hot skillet, and sear for 3 to 5 minutes on each side. Be careful not to overcook, this fish should be served still a little pink in the center. Serve with sauce.
