Well for those who cant view it its a 13 min piece, much of it appearing from propaganda rolls, showing the Japanese fighting back against the B29 raids. Theres a lot of clip showing downed B29s, very few of which happened due to enemy action, and some great shots of IJA fighters either taking off or trying to gain air on B29 formations. I wish I knew IJA aircraft better, maybe someone could comment which ones are in the piece. I thought there were some KI-100s in the short but again Im not sure.
Its all cobbled together to make the Japanese feel like they were fighting an effective defense against the B29s, which of course they werent. Theres so little of this kind of material that survived the war. They destroyed so much film, documents, records of any kind "war? what war?", blaming it on our bombs, that its always a treat to watch this kind of footage.
