When written top to bottom, the columns are read from right to left. This is the most common format for printed text, especially in Hokusai's time.

Also, when text was horizontal, it was frequently written right to left until the mid-1940s.[1]

Again, even in the scenario you are describing, it is right-to-left when it comes to organizing columns/page layout (just like it would be with manga), but the text is still not right-to-left. It is top-to-bottom text vertical columns going left-to-right horizontally.

There is not a single instance I can think of where the actual text in Japanese would be read/written horizontally right-to-left.
