1) This is the climactic finale of the 2007 Japanese war film "For Those We Love" (original title "Ore wa, kimi no tame ni koso shini ni iku," or "I will surely go to my death for you"), dramatizing the IJAAF Special Attack (kamikaze) pilots based at Chiran, from the POV of a famous innkeeper who was considered the "godmother" to the Tokkotai pilots:

2) The film itself is essentially 2 hours of drama followed by this high-budget searing climax, boasting some pretty impressive CGI and miniatures FX...

3a) Also of interest, two Japanese-only video clips from CGI animator Masaru Tochibayashi. While not familiar with his work, I presume he must be heavily involved with some of the CGI in recent Japanese movies. These are really impressive, and they're NOT from the History Channel's "Dogfight" series:
This dramatizes the combat sortie of IJNAF ace and Zuikaku fighter pilot Tetsuzo Iwamoto on May 8, 1942 during the Battle of the Coral Sea, as he flies CAP protecting the carriers Shokaku and Zuikaku from USN air attack:

3b) This one dramatizes the combat sortie of the IJNAF ace Saburo Sakai in the Tainan Kokutai's first and most famous sortie against USN F4F Wildcats off and over Guadalcanal, August 7, 1942, resulting in the famous duel between Sakai and USN LT James "Pug" Southerland (both survived the encounter).
