All you need to do is have the card and you can use “Smart EX” to make online reservations for the Tokaido and Sanyo Shinkansen, and “e5489” to use the Shinkansen in the JR West, JR Shikoku, and JR Kyushu areas, as well as some areas of JR Central and JR East, at a discount. You can earn up to 10 times the points when using J-WEST Card point preferential stores, and these can be exchanged for SMART ICOCA points.
