best day for shinkansen round trip

Hi Chris Hill,

It will depend on how much you would want to spend on a ticket. Kobe is located in the Kansai Area, you can take the bullet train to Osaka in 20min, Kyoto 50min. Trips that take a bit longer and are also worth considering would be a visit to Himeji or Hiroshima. Train services are frequent and you could come early to the station to return later the same day.

Hope this helps,
Daniel
