Is 10 minutes time enough to transit from Shinjuku station to Shinjuku Expressway Bus terminal?

Just rechecked my itinerary and realized that one of the transit time between train and bus is only 10 minutes. Is it enough? If it isn't, I plan to rearrange the itinerary

Train will arrive at around 10:55 and the expressway bus will depart at 11:05. I'm carrying a luggage at that time
