Yu Yu Hakusho Volume 1 Japanese and English Covers. And also here's how all the Japanese volumes look side-by-side for the sake of it. I don't know what part Togashi has in his series' book release designs, if anything beyond the covers.
Here's the cover and the first couple pages of Oobo— Nu— Tochiibo— Nu—(おおぼーぬーとちぃぼーぬー), which is a children's book that Takeuchi came up with the story for and Togashi drew. It was published in 2005. You can see all of it here: https://t.co/nW6QJ12DJR
