which train /company to travel with

Hi Noa,

In general, you can consider a 7-day JR Pass if you make a return trip Tokyo - Kyoto using the pass. You can use the Hikari Shinkansen for free, or pay a nominal fee to travel on the Nozomi. The pass is similar in cost as a return ticket (if you order before the new pricing) and when be especially useful if you cover any additional transport with it (think of the local JR network, day trips and travel to the airport).

Tickets can be purchased 1 month before travel, and we recommend doing so at any station.

Kind regards,
Daniel
