Night train

Hi there,

You can use the JR Pass on the Sunrise express:

The Sunrise however does not stop at Osaka but you can get off at Himeji and take a Shinkansen from there to Osaka.

The Keisei Line and Hankyu-Takarazuka are private lines and not included in the JR Pass.

Hope this helps,
Daniel
