Japanese Geisha Dancing Panels

This humongous painting has been collecting dust in my garage for a couple of years.
I bought it at the same estate sale where I got the cinnabar vases. I just happened to see this exact same panel on 1st dibs for over a thousand dollars so thought it was time to dust it off and bring it inside.
I don't think it's an original painting, but looking at it under magnification, I don't see any print dots. So I'm wondering if it's a lithograph of some kind? Any help in identifying this would be most appreciated.
