There is a toll for travelling depending on the distance. You take a ticket as you go on to the highway, then pay at the exit. The highway fee to Tokyo from Sakura is Y1300, from Yatabe Y1100 and from Yawara Y750 (see links below). When you enter the "kosokodoro" or the spaghetti-like network of routes that thread through and around Tokyo, there is a Y700 fee. You may exit anywhere in the Tokyo metro area for free after this point. The prices between one exchange and another are listed in many Japanese road maps.
