Nagoya is conveniently connected to Shinshu with the Limited Express Shinano which runs every hour.

Nagoya is also on the Shinkansen line, if you are coming from / going to Kyoto or Osaka, you are most likely to change at Nagoya.

If you are going beyond Nagoya to Kyoto or Osaka by Shinkansen, the limited express ticket for Shinano will be reduced. To receive this benefit, you need to buy tickets in advance. (Not available on board)

Direct highway bus services from Meitetsu Bus Terminal (adjacent to JR Nagoya station) are available to Nagano, Matsumoto or Iida-Ina areas. No bus to Suwa-Chino area.

Centrair is served by Meitetsu trains but not JR. Some Meitetsu trains go to Nagoya station while some terminate at Kanayama station.

If you are taking the JR Express Shinano for Matsumoto and Nagano, you need to change to the JR line either at Kanayama station or Nagoya station. However, Shinano does not stop at Kanayama, so you need to catch a local train to Chikusa and transfer to the Shinano.

Direct highway bus from Centrair goes to Matsumoto and Nagano, however the service is limited. Door to door shuttle is also available for Nagano and Suwa areas.
