Shinkansen transfer station to Ueno

JapanBuff: You would just go down the escalator in the Tokyo Shinkansen Station then go back up the escalator to the correct track to Ueno.

That�fs not correct.
In Tokyo Station, JR-Central and JR-East have different Shinkansen zones.
In order to make a transfer smoothly between JR-Central Tokaido Shinkansen and a JR-East Shinkansen line, passengers should pass through a gate between the two Shinkansen zones.
So, it�fs not just going down and up escalators.

cf.
In Shin-Osaka Station, JR-West and JR-Central are using one Shinkansen zone, which is managed by JR-Central. There is no gate between the Shinkansen lines of JR-West and JR-Central. JR-West is managing the non-Shinkansen zone of Shin-Osaka Station.

omotenashi:
Thank you for the clarification on the Shinkansen gates between the two JR companies.

I am going to do this in reverse and would appreciate knowing which would be easier.

I have a JR Pass and will be going from Ueno to Kyoto. I have a large bag.

Which would be easier: Shinkansen from Ueno to Tokyo Station then transfer to Shinkansen for Kyoto.

or

JR Yamanote Line from Ueno to Tokyo Station or Shinagawa Station then transfer to Shinkansen to Kyoto.

We are staying first night in Kusutra Onsen, not sure to stay 1 night in Ikaho or Minikama? We are coming from Tokyo , please advise what is the nearest station to and back to shinagawa station? Plan to rent a car to travel around Gunma. Can you recommend which station to pick up n return the car. Thanks.

Please adv isn't correct to take train direct from Shin Osaka direct to Shinagawa station?
