I would add, that we used the trains extensively, including the Shinkansen.
If you report to the kiosk at the ticket barrier with your ticket / seat reservation. You will escorted to the right location on the platform. Put down a ramp (slope) for you. On the Shinkansen our travel agent booked seat reservations next to the vestibule. We collapsed the wheelchair and put it behind the seat.
Station stops will be less than a minute, so be ready in advance for getting off.
There will be station staff at your destination station with a ramp for you.
On other trains there will be a designated area for the wheelchair.
