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