Masashi Ishihama said he remembers drawing 「試験管をパチンコ玉で割る」

which is actually not in the movie, however this is the only scene with pachinko machines. I believe his work was scrapped due to storyboard/script/editing phase changes which makes it difficult to credit this part. He may have still drawn the layout of the game corner, with the cuts he specifically remembers removed, or it was completely redone.
