The way the Japanese Spoke
I found it interesting, particularly if you're not reading the subtitles, what the sound and inflection is like when they talk. The women sound soft and musical, but the men sound very deep and guttural, particularly when talking among soldiers. Sometimes their words sound like darting bullets.
My dad found it funny when Lord Toranaga was doing a big pep-talk speech to his soldiers in one part of the series, the part where he's raising a fan and going "eee--EEEE--eeee!!!" Dad said Toranaga sounded like he was trying to take a dump instead, hehe.
