 Starting from a Proustian approach of food, Oshii tries to recreate 60-years of Japanese dietary history in his ""Documentary of Shōwa underground"".This work is actually a false documentary style animation movie, which borrows and develops some key elements from his 1987 debut live-action feature, "The Red Spectacles", e.g.the stand-and-eat ("tachigui"), the post-World War II retro background, the "avant-garde" visuals and screenplay, and even the "tachiguishi" theme with returning characters like Moongaze Ginji.
