THE TWENTIETH CENTURY: TYPHOON AT OKINAWA (1957)
The venerable Walter Cronkite: "This is the story of two winds: the brutal wind of the typhoon and what the Japanese call 'The Divine Wind' of the Kamikaze.". It is also the best short documentary there is on the subject of Kamikazes, with films of their attacks that rank among the best of all World War II combat footage.

G. I. DIARY: KAMIKAZE: FLOWER OF DEATH (1978)
Exquisite colorized films give a realistic view of what kamikaze attacks must have looked like in a physical as well as a cinematic sense. Lloyd Bridges narrates.

SURVIVAL!: KAMIKAZE (1964)
Well chosen footage complements a storied narration with emphasis on both the land operations of the Battle of Okinawa as well as the naval engagements on the land and in the air.
