There are ken-ken shops near most large stations, and scattered around town, as well (see the map for locations in Fuji and Shizuoka). These tickets shops sell a wide variety of discount tickets, including Shinkansen tix, telephone cards, movie theater tix, beer coupons, and more. Just another reason not to pay full price!
