Daiei Film
"Giants and Toys" was a short story written by Takeshi Kaikō. After Kaikō won the Akutagawa Prize in 1957 for "The Naked King", Daiei Film bought the rights to "Giants and Toys." The story was an entry in the "business novel" (経済小説, "keizai shōsetsu") genre, which satirizes Japanese workers' devotion to their corporations.
