There is an amazing movie from 2011 called The Admiral. It is a Japanese movie and tells the story from the Japanese perspective. The main character is, of course, Admiral Yamamoto. He was very much opposed to war with America for years but was overruled several times. It’s definitely worth a watch if you can find it.
New movie “Midway” is in theaters now. Starts with Pearl Harbor and ends after the victory at Midway. No “name” actors except the relatively small role of Woody Harrelson as Chester Nimitz. The film is visually stunning with no romantic backstories taking attention from the decision-making on both sides. Divine intervention imo caused Japanese intel to miss that the 6 U.S. aircraft carriers weren’t in port that day.
It’s an excellent film.
Admiral Yaamamoto had been posted as a naval attaché to the US. He knew there was a lot more to the US then the Japanese decision makers realized. That was true in general for many of the naval officers, their service gave them a better understanding of what Japan would be up against. The Army officers for the most part had hardly been out of the area. If they had been out of Japan, their foreign experience had been China & Manchuria, they looked at possible opponents through that lens. (The Soviet-Japan border clashes in the 1930s were a huge shock to the Japanese Army. Apparently the lesson didn’t stick.)
