Do many of Americans know "Ultraman"?
I watched Ultraman all the time as a kid on TV. And of course Gojira and Mothra and Gamera. And any other kind of tokusatsu TV. And Astroboy (Mighty Atom). As well as Kimba the white lion (hence my nickname Leo and Lyre). Plus lots of other Japanese TV which I had to read the subtitles to watch.
That was all in the '70s and early '80s. Then in the '90s came the doramas. One of my favorite shows of all time was Ienakiko (with Yumi Adachi), which was subtitled and aired as "Angry Innocence". I have been searching for DVDs or CDs of that show for years and years.
