“Watashi wa” is actually not the subject of the sentence in Japanese. It’s what is called a theme, as in: this is what we are going to talk about, the topic. Example: “Watashi ha hamburger desu”: With regard to “Watashi” = me/I (i.e. concerning “me”), “it is” a hamburger, Which ends up translated to: I am a hamburger. Or: For me, it will be a hamburger. So the “wa” particule (actually “ha”) introduces the theme or topic in the sentence, rather than the subject. Very different from English. Reference: theme and rheme in Japanese.
