I noticed something that was quite inaccurate to a Japanese royal salute of that timeframe towards the royals. Which is actually displayed properly in another ww2 movie depicting an actual event of the Japanese surrender and us arrival on Japanese soil at the end of ww2. When the Japanese present arms to the royal family they will do an about face away from them so that all weapons are presented outwardly and not towards the royals. The only noted time during/after ww2 timeline in which they did such to non royals was when the general landed at the airbase and was being taken to the location in which the signing of Japanese surrender was conducted. (Sorry just the way they conducted that salute was so weird)also a German aristocrat salute was conducted as a slamming of heels together as the utmost of respect, the whole raised hand all the time was a propaganda us and ussr created to make them look stupid; the hand thing was only for the Austrian boy; furthermore this was propaganda against them just as when they created the name nazi (meaning ignorant and foolish) for them. And before people think I support the nazis, I don’t just a huge ww2 nerd since that was the age of the greatest generations of all people when it comes to technology, manufacturing, and determination.
