I just purchased the JRpass, and have a question regarding the "seat reservation" of Shinkansen.
I just checked the website of JR East, the Seat Reservation (Shitei Ken) cost about 5,500yen. My colleague told me that seat reservation cost just 1,500yen.
Could you tell me what is the cost for seat reservation of Shinkansen when you have a Japan Rail Pass?
Thank you for your time
