The opening credits sequence for the collection was directed by Hanada Daizaburo.
"Kijou no Kuron" or "Armchair Theory" is a satirical instructional film for how to woo a Japanese woman.
Kojima followed this concept with a series of short films under the title "The Japanese Tradition" (日本の形).
"Sushi", "Sumo", "Golf", "Geisha", "Apologizing", "Tea" and "Chopsticks" all follow the satirical plot of taking a Japanese custom and often twisting or exaggerating its components or meanings into something meaningless or comedic.
Both short film series feature Jin Katagiri (片桐 仁) and Kentarō Kobayashi (小林 賢太郎), a Japanese comedy duo collectively knows as Rahmens (ラーメンズ) who often are a part of scriptwriting and production.
