Luggage rack in Gran Class car of Hayabusa

Is there a space to put luggage (not overhead) in the Gran Class car of the Hayabusa Shinkansen going to Aomori?

Similarly , there is no luggage storage for the E5 series Gran Class (car No. 10) . (Luggage shelf above the seats only) If you have large luggage that cannot fit in the luggage rack, please use the space between the rearmost seat and the wall or the luggage storage area on the deck of Car 9 .

Thank you very much.
