If your ticket's origin/destination says "City Zone," your Shinkansen tickets include local train rides within big cities before/after riding Shinkansen on the same date. These "City Zones" are valid for Sapporo, Sendai, Tokyo, Yokohama, Nagoya, Kyoto, Osaka, Kobe, Hiroshima, Kita-Kyusyu, and Fukuoka. For example, you can start using your Shinkansen ticket from any station like Shibuya or Shinjuku in the central Tokyo area, use the local JR train to Tokyo station, ride Shinkansen to Shin-Osaka station, then switch again to the local JR train to any station within central Osaka area.
