My son played Pokemon Stamp rally today. It is a game collecting series of stamps which are placed at certain stations. My son collected 6 stamps in downtown area. He used a one day unlimited ride pass to go around stations. The pass is called One day Tokunai pass, cost 360 yen ($3.71 €2.77). It is the kids price. The normal price is 720 yen ($7.42 €5.54). You can ride Japan Railway as many times as you want in the range of Tokyo 23 wards on the specific day.
