Well, you already said everything that I wanted to say on what I like about Japan itself, but let me just explain my side. :P
On Japanese tokusatsu live-action, it's practically obvious to me since I've watched more toku than anime. In fact, I've had my very first exposure to toku a few years BEFORE I've had my exposure to anime (if I can remember correctly, my very first anime is Chōdenji Machine Voltes V, while my very first toku is Chōdenshi Bioman).
On Japanese kaiju, well I really never remembered on why was I exposed to Godzilla or something, but I think it's around the same time as my exposure to Ultraman.
On J-music, well it depends. Most of the time, I only listen to OSTs of anime and others, but some are practically good, mostly from the J-rock genre.
On Japanese girls, well I might not be on the same intimacy level as you, Hantei, but still, their cute eyes make me fall for them.
